Only expirienced testers are allowed to post here.
All good settings will be accumulated to first post, and deleted later.

1) PappasArts settings (see his thread for more details)

Settings for achieving 1440X1080-30P Finale V.1 [ CLASS 10 HIGH QUALITY CARD NEEDED ]
MJPEG 1280p width - input 1440
MJPEG 1280p height - input 1080
MJPEG Encoder 1280m-1920m - checked
QUALITY SETTINGS [ 384, 330, 300, 276 ] TABLE SETTINGS [ 24, 24, 24, 24 ]

HOW TO SHOOT 720P/30 IN 80Mbits MODE

QUALITY SETTINGS [ 384, 330, 300, 276 ]
TABLE SETTINGS [ 24, 24, 24, 24 ]
This mode give you a glorious 720P at a very high bit rate.

2) Paul Shields Settings, 1280x720

I did also find settings that were giving me over 70Mbit/sec without issues.
E1 256, E1 table 8, E2 256, E2 table 8, E3 256, E3 table 8, E4 256, E4 table 8.
If you set the table values to 5,5,5,5 then as well as recording ok it also plays back nicely in camera. The footage I've shot shows bitrate around 34Mbit/sec.


P.S. Note lens used can affect maximum usable bitrate because camera perform geometric, CA and vingetting correction for many Panasonic lenses.
Best is to use manual lenses for tests.

AVCHD STABLE SETTINGS FOR 1080P

C Settings:

-Video bitrate adjustment - c)50000000
-Overall bitrate adjustment - c)52000000
-Limiting bitrate adjustment - c)60000000

AVCHD STABLE SETTINGS FOR 720P


If you shoot in 720 60p mode, D settings probably won’t work with high detailed scenes and camera will interrupt recording after few seconds. For 720 MODE use the following settings that will work without problems:

Video bitrate adjustment - 38000000
Overall bitrate adjustment - 40000000
Limiting bitrate adjustment - 42000000

For these settings avg. bitrate in 1080 MODE is 34.4 Mbps and for 720 34.5 Mbps.
There are no problems with recording of any kind either with 1080 or 720.
No MUD with this setting also.
I should say that these are stable settings and I would recommend them for normal users that want to shoot with 1080 and 720.Jobless's thread on AVCHD Settings: http://www.dvxuser.com/V6/showthread.php?p=2012634#post2012634

***WARNING***
Your results might be different and these settings might yield card errors.
The two cards yielding the fewest card errors seem to be the
Sandisk Class 10 and Panasonic Gold Class 10 cards.

The best, and most stable, AVCHD settings I have found so far are 50,52,60 (the "c" suggestions) with Native 24p not checked. I am using Transcend 16GB class 10 cards. With the Sandisk Ultra MCXXLV Sooper Dooper Card you probably could get away with the 60,62,70 settings.

The Transcend class 6 cards fail occassionally with a write error with the 50,52,60 settings. The 60,62,70 settings fail occassionaly with the Transcend class 10 cards.

Native 24p checked produces rogue frames (spikes) with all settings, even factory default settings.

Fast shutter speeds (e.g. 1/500) increase I frame size considerably, but not the overall data rate, so I assume the IQ suffers somewhat. High sharpening (which is a complete waste because it can be better done in post) and low noise reduction (setting the NR a little higher might actually be a good thing) settings do too, although not as much. OIS and autofocus appear to degrade the camera's ability to write to memory somewhat - probably because they stress the CPU.

So for me optimum settings are 50,52,60 - Native 24p not checked. These settings work no matter the subject, or how much I zoom the lens in and out, when OIS is on, autofocus is on, auto exposure is on, shutter speeds are high (1/500), NR -2, and Sharpening +2. That's as close to a worse case scenario as I can come up with.

I can film normal real world stuff with 60,62,70- however the star chart causes the write error. 50-52-60 are good. In another thread moments ago it was posted that they did 50-52-60 settings with a GOP4 and preliminary results showed a jump in Mbs. I havn't tried it out yet.

By the way, I did not change GOP settings - I left the 1080 GOP at 15, which corresponds to the standard 1/2 seconds between I frames when using the wrapped (Native 24p not checked) mode. I haven't noticed that changing the GOP makes much difference in quality one way or another.

Here are the following stable AVCHD settings I have found for my Transcend Class 6 16GB card. I am testing with the 14mm-140mm lens kit.

(The first column denotes max Mbps, as shown on Windows, found on one of my clips)
26mbps -> 28,30,34 Native 24p/25 ON
29mbps -> 30,32,36 Native 24p/25 ON
31mbps -> 32,34,40 Native 24p/25 OFF
33mbps -> 38,40,42 Native 24p/25 OFF (720P fails while zooming with AutoFocus but zooming is OK with Manual Focus, 1080P solid so far)
35mbps -> 40,46,50 Native 24p/25 OFF (720P fails while zooming/panning with AutoFocus and Manual Focus, 1080P solid so far)

My film mode settings are: Smooth settings, -2 Contrast, -1 Sharp, -2 Noise Reduction, OIS always on. I have informally tested these settings by performing my daffodils of death test and, more importantly, using my camera on field trips.

I'm going to try and squeeze some more mbps out of my card; will report back soon! And, last but not least, thank you Vitaliy and other testers!

Anyone have New, Stable 720p 30 MJPEG settings
the kind that are beautiful like "PappasArts settings", and "Paul Shields Settings"
that can run all day long on a Scandisk Extreme class 10.
On Pauls I got about 3Gigs in and had Write failure and on PappasArts I went alittle longer
but fail as well. Just as a note I also notice when I change from my 75mm to 22mm
I also get write error wt Avchd (C) settings. In same light, same scene, same Stops (I'm guessing 22mm

Q: 256, 220, 200, 184
T: 5, 5, 5, 5

I have 4:2:2 checked and get around 70 mbps.
Camera records fine. AFC, live histogram, 1/125 or 1/30 shutter speed are no problem.

What card are you using? If you want to go with the higher bitrates like the 70Mbps + range you'll need either the 32gig Scandisk Extreme Class 10 card or the Panasonic 32gig Gold Class 10 card. I myself have the Patriot 32gig Class 10 card and it seems to fail around 53-54Mbps. I spent a good chunk of the day today trying to find stable setting around that range. I'm very close with the AVCHD modes, but not so much with the MJPEG mode.

You can see my progress along with others here.

Thank you Martin, Brian,

I just got back in town from a shoot, Martin I'll try those MPEG setting, I got my camera back
around 45mbps and shot some Commercial stuff (in controlled light conditions)
and no freeze/write problems.

Brian, I am using 16gig Scandisk extreme II class 10... I'll pick up some 32's ASAP...
also thank for the chart link a can relate to I've been keeping my note pad.

Thanks guys !

What are the best C values for?

Video Bitrate Adjustment H
Video Bitrate Adjustment L

?

cbrandin
07-01-2010, 08:36 AM
The best settings would be the same as what you put in video bitrate - but that would be silly. It's entirely up to you. There are there so you can enter lower values and get more time at the expense of quality. I like the "C" settings, so I put the video bitrate settings from "A" and "B" in them. Not sure I'll ever actually use them, though.

One thing comes to mind. Sometimes the "C" video bitrate works fine in FHD mode bit is too much for SH mode (which actually produces more data). Putting a somewhat lower number in H might make 720p usable. The video bitrate setting is a combined setting for FHD and SH modes. If you use the highest value that still works in FHD mode chances are SH mode will produce write errors. Using H mode might be a good way to get around this.

Chris

Thanks Chris.

So any are the numbers for H & L for C settings, for FHD only, and for FHD and SH?
And is it better to leave them unchecked?

I don't get this fields...

cbrandin
07-01-2010, 09:56 AM
The video bitrate setting is for FHD and SH - it applies to both. The H video setting is just for H and L just for L. I'm guessing (although I haven't tested this) that if you put the same settings in all three the H and L modes will become the same as the SH mode.

The "C" settings are utterly reliable for me in FHD mode but fail in SH mode. I'm going to try putting just a slightly lower number in H and see if I can stabilize 720p mode. That way I can have my cake and eat it too as long as I ignore the SH option.

@cbranding That sounds like a great idea, let us know your findings!

I am trying to find out how high can I push te bitrates using the cards I have for my GH1, Transcend 8GB Class 6. I tried cbranding a jobless idea of using H and L setting to have other 720 60p alternatives in case SH failed.

I tried with this settings
VBA FHD/SH 40000000
VBA H 36000000
VBA L 16000000
OVA 50000000
LBA 60000000

No native 24p enabled.

My idea was to push FHD/SH as far as some people had reported would work on Class 6 Cards. 40/50/60. Since 720 60p has been reported to fail at settings that FHD held up well the L and H settings would allow me to try to make 720p when SH failed.

Took my GH1 to a place full of grass, leaves and trees and did several tests.

FHD was pretty robust, almost mud free and wouldn't fail recording under any circumstances.

SH failed when I moved around quickly or if I tried to zoom.

H held up better moving around and zooming but also failed sometimes.

L held up well all the time.

cbrandin
07-07-2010, 09:49 AM
My theory about using the H and L settings to stabilize 720p didn't work out. It seems that the Limiting Bitrate plays a dominant role for stability. I can use the "C" settings reliably for AVCHD 1080 mode, but write failures occur in 720 mode. Even if I set "H" to a very low value (20), I can still get failures. This actually does make sense because the Limiting Bitrate is still high (60). I suspect the H and L (and SH, for that matter) settings will be of limited utility unless the Limiting Bitrate can be lowered without affecting 1080 mode.

Is there a way that Limiting Bitrate can be set separately for each AVCHD mode? Or, alternatively, can there be one setting for 1080 mode and another for all 720 modes?

Chris

dmoreno
07-09-2010, 11:11 AM
I was able to stabilize 720p using your theory.
This were the settings I used: FHD/SD bitrate: 40, H bitrate: 22, L bitrate: 18, overall: 44, limiting: 50.
Wasn't able to make the card fail using the camera in FHD and in L. It did fail in H, that has that low 22 mpbs bitrate. I even tried 20 mbps and it would fail if I zoomed in and out like crazy (shooting trees and grass).
I wil use H as my "normal" 720p mode as it rarely fails. L will be kept as a 100% robust setting in case H fails.

cbrandin
07-09-2010, 11:33 AM
Actually, you got close to what I found. If you reduce the limiting bitrate from 60 to 50 and the video from 50 to 40 the 720p works (at least for me). Having to reduce the video bitrate from 50 to 22 is a lot bigger change. I was hoping a small change would suffice, as it does when you also reduce the limiting bitrate.

My stabil settings for 1080p 24 or 25p not native are 40-46-50 with transcend class 10 card. I also tested C settings, working fine but stops recording some times at long time shots.
With both settings there is still mud in dark areas if you stress the codec for example with leaves in wind. But it's a big difference to the ammount of mud you can see with standard settings.

Is the picture mudfree with much higher settings with a faster card or is there still mud? Any experiences?

Preset Bitrate2 - not ticked
Mpeg Settings are the ipowell 35mbps reliable ones with 422 checked

The absolute lowest the bitrate dropped to was 21mbps, the highest was 43mbps, Average was 27 - 34Mbps.

I shot grass, trees, pinebark, rocks, sand, tripod lock off shots, whip pans waterfalls, nothing gave an error.

I could not even get Pappas Star Chart to fail , so these are what i have settled on for now and given up completely on 25pN

In SH 720p mode the bitrates were overall lower by about 3-5 mbps

I don't believe a faster card will make any difference, 24/25pN is flawed in my opinion on any card.

My findings for extremely cheap Verbatim class 6 16gig SD cards in a GH1 -

Up to 28mbit works and seems to be stable (28m, 30m, 34m). The recommended settings for 32mbit (32m, 34m, 40m) cause the card write speed / crash error on demanding subjects.

I've found a good test subject for stability testing is a full frame of leaves at the top of a tree on a breezy day (the 10x zoom lens comes in handy for this). The encoder has a hard time with all the random motion of individual leaves (panning by contrast is much easier) and checking the files afterwards it seems to be using the absolute maximum bitrate for the entire clip.

It's probably why the mud problem on lower bitrates affects foliage so much, and gives a good indication of the quality improvement of higher bitrates too.

I use Class 6 Cards and the SH mode (720p) wukk make the card fail on even lower settings than the the C settings if I tried zooming in and out with the kit lens (pointing to a tree full of leaves and grass) even if i set everything on manual (aperture, shutter, iso, focus, everything). Haven't tried zooming with a full manual lens, I have an old Vivitar 70-200 mm with Canon FD mount, will try on the weekend and see what happens.

Even using FHD/SH bitrate at 40 (limiting 44, overall 50) my class 6 card would fail in SH. Wouldn't fail in FHD.

My Class 6 Card is a Transcend, and is slower than a Class 6 rated Sandisk. I am also on NTSC land so the 60 fps could require faster cards than the 50 fps, just guessing.

Yes i'm aware of the majority of people reporting SH failing before FHD, that was a surprise to me as any time i had a failure testing higher bitrates it was always FHD that failed, so was the opposite. As you can see even my reported SH data rate is 4-5 mbps under FHD. Even with 25pN enabled SH failed much less just FHD. I almost settled on SH as my preferred mode because of it.

I have been studying the AVCHD from my HMC 152e in Steameye and it has relatively speaking the same large I Frames compared to P frames, so no clues there as to what is going on but the B Frames appear to smooth out the P Frames or keep them under control somehow. I'm not knowledgeable enough to analyze encoders but a keen eye can sometimes pick irregularities.

I'm hoping someone can come up with the solution but we seem to be depleted of testers helping now, as someone said like a Ghost town in here.

Ok ignore that, I forgot I had 25p enabled which causes it's own problems. I've just done a speed test with HD Tune on my sd card and it reports 13-14 MB/sec (not bad for the cheapest 16gig class 6 card on amazon). In theory that should be capable of 100mbps, I'm going to do some more test on my original test subject once the wind picks up (annoyingly it's perfectly still today)

When filming Pappas' "screan of death" you should use the full screen image, the one you're testing against covers about 55% of the screen area which is not kind of "torture" test.

Yes i know, that was one of many shot at different FOV's 50% - 100% and others were shot with 720p SH mode also.

I'll post the 100% coverage shot if you like tomorrow , same deal, i turned it off after 2 mins.

Has anyone tried dumping the bitrate of the audio, in order to squeeze out more image bps? I usually use separate audio recording gear, so the audio from the camera is redundant... the audio must use some bandwidth and cpu, and I was curious what image the gh1 could record if it wasn't working to record audio at the same time.

There is no way to go lower on audio with the current pTool, but I like your idea and it will be interesting to see if it will allow CPU to perform better on video processing.


Has anyone tried dumping the bitrate of the audio, in order to squeeze out more image bps? I usually use separate audio recording gear, so the audio from the camera is redundant... the audio must use some bandwidth and cpu, and I was curious what image the gh1 could record if it wasn't working to record audio at the same time.

Here is the setting I have recently started using. So far it has not failed me once. Not even when testing on charts. It is not the patch to achieve highest bitrate footages, but it is stable, it is native 24P, and I get around 16mbps for not so detailed scenes and 24-25mbps for high detailed scenes.

I usually pretty good at following mod instructions.....that said....I am getting really confused with all the different posts and settings.....its seems to me that posts for stable settings should be organized my what type of card you are using......I have the sandisk extreme 32gb 30mbs card and would like to install optimal settings.....my cam is brand new and un-modded.......I would also like the ability to return to original firmware including version number.......I am a film student and require optimal stable settings while getting the most out of this new card........someone please help!!!!!

if you have the sandisk 30mbs card you can use any settings really...I feel the modulr settings (you can download the setting in these very same forums) is the most optimal...especially for mjpeg

Back to the 7D with even worse auto gain control, color chroma aliasing, and lower resolution. Just saying, neither is a perfect solution.

First up you need to relax...go on this thread read through and download the the mods that suits your needs and install them in ptool.

If youve hacked things before then it should be very simple.

When you see modulrs 70+mbps 100% mjpeg or the "c" setting avchd theyre are a lot better than the 7D.

Most importantly you wont know what youre missing unless you TRY IT.

You currently have the most stable SDHC card for ANY of the settings.

Just not have 24/25p patch ticked as its buggy.

Why am I always bringing bad news?!? :embarasse
So, Pappas's chart (printed) failed after about 30s under artificial light. FHD, 1/30s shutter, 25p (PAL), ISO 640, fully opened lens, tripod, 14-140mm, Transcend 16G class 10. I suppose that it would fail sooner outside. Will try without 25p and let you know.

As expected, still under artificial lighting and all other conditions the same except in 50i mode and with added bulb, it stopped recording after about 1s without displaying any warning. The file was not stored.

I may sound dumb with my question? Why do we need to enter values for E1 to E4, as opposed to just one overall? And do I really need to follow a downward numerical sequence as it i suggested in the displayed formula in Ptool, yet some of the testers propose the same numerical value to be the same in E1 to E4?

I'm playing with the GF1 not GH1, and just managed to squeeze MJPEG to a more 4:3 image as opposed to 16:9, by entering 1440 x 1080, will revert back to 720 p,
after reading that my chip cannot deliver Full HD 1080.

Also I will try to mod the AVC settings, as for GOP, I can only suggest from my past
video knowledge to really lower the rate, if you ever intend to edit your footage.
Its just better to have more I frames as opposed to lots of B and P frames.

Keep the great work going...! And thank you for help with the E1 to E4 question...

Playing around with settings (I am doing comparisons between AVCHD 720p and MJPEG 720p) I noticed that the codecs interlace scanlines differently-- could someone double these tests and confirm them?

I was shooting images off the television (old cathode ray tv, PAL) because I have found this a good way to crash a codec. The mjpeg, when shooting at 1/50th sec shutter speed showed the rescan lines you would expect, a static band not really rolling (actually very minor and nice looking for this type of shooting. The AVCHD, both in 1080 25p and also in 720 25p (I had dropped the framerate in firmware), showed totally different scanlines both in the viewfinder preview and in the final file-- a sort of double-banded rolling rescan line. This makes me think that the process of capture to compression is different for AVCHD-- not a truly progressive capture data flow-- maybe related to 'rolling shutter' artifacts?

Anyone else seen this difference?

HOW TO SHOOT 720P/30 IN 80Mbits MODE

QUALITY SETTINGS [ 384, 330, 300, 276 ]
TABLE SETTINGS [ 24, 24, 24, 24 ]
This mode give you a glorious 720P at a very high bit rate.

2) Paul Shields Settings, 1280x720

I did also find settings that were giving me over 70Mbit/sec without issues.
E1 256, E1 table 8, E2 256, E2 table 8, E3 256, E3 table 8, E4 256, E4 table 8.
If you set the table values to 5,5,5,5 then as well as recording ok it also plays back nicely in camera. The footage I've shot shows bitrate around 34Mbit/sec.


.


Used both settings but have time limit issues on my Class 10 32GB Sandisk. Any idea why? 2:40 and 4:50 respectively between the two settings and the second setting with the 5555 table has writing speed issues?

Yes, it is clean, but unfortunately we can't get true a 24fps out of the camera. I did a frame timing test and my results showed that 24fps in MJPEG mode is produced simply by dropping every fifth frame from the hard-wired 30fps video stream. Here's a link to my original post:

Hi Martin,

I tried all the settings suggested in this thread and kept getting write errors. Then I tried your suggestions (above) and haven't gotten a write error yet (but haven't tested much), but also cannot view the video in camera.

Does anyone have any MPEG settings that will work for a SanDisk 8 Gig Class 10 card that will not have write errors and also let me play it in camera? I don't need super high bitrate. Anything decent is fine (maybe between 30-50Mbps?).

I usually shoot AVCHD 720p SH mode, but I often find myself in dark situations without extra lighting and since 720p SH footage dies under 60 fps, I am trying to have a decent MPEG setup to do 30 fps shots when in darker conditions.

Thanks for any help. By the way, I am using PTool 3.50d

I actually found some stable MPEG settings provided by LPowell in a different post. I tried them out for a day and although the footage played in camera and was considerably smaller, I was not happy with the quality. I have now decided to deal with the "not playable in camera" issue so that I can have higher quality footage.

I am relatively happy with my current settings. I am using Martin's MPEG settings and Jobless' stable 720 AVCHD settings. So far no major issues (other than some strobing in flat/underexposed areas with AVCHD) and in general I am happy with the results. I am using AVCHD 720p for general purpose shooting and MPEG 720p for tricky scenes that break the AVCHD (but sparingly since the files sizes are HUGE and eat up my disk space very quickly).

Here is a recap of my current settings:

MJPEG:

OK - I love the ability to shoot in low light and have a relatively inexpensive way to shoot with film lenses - Previously I have been using a movietube SLT with PL and Nikon mount with a HVX 200 - but loose so much light - and HVX small chips - that I have to use a lot of light to get the effect I want - I used probably three 2Ks and three 1ks for backlight (mostly aimed towards camera) and two 2ks and a one 1k for front light to get the cool club looking effect in a music video for example -
it is worse then shooting on film - which I would have been able to use half the light -

this is why I have been playing with HDSLR - but no matter how much I try (although greatly improved) - I still get this banding in the shadows that makes it unusable - the workaround has been to use more light and then in post use mattes - but it is the ability to shoot shadows and areas of dark that I am interested in - I have linked a photo (from a test mpeg movie) using available light shooting wide open at 1/30 sec - with the pancake lens the settings are basically the I stable settings I got from somewhere on this board - modified for 24 p = link to picture -<a href="http://ampfilmstudios.com/gh1">frame grab here </a>

So my question is about the compression in the frame grab both the shadows (upper right) and the worse part - the graduation from shadow to light (in the lower left) - does anyone have settings they can share with me that has been tested to work already - AND why not publicize and make available for down load the actual firmware? ALSO understand that they way many of you express your settings makes no sense to me - in some respects - I want compression that will give me great color - great image in low light - no noise and no banding - and no MUD - as u can see from the frame grab - I want better image -

Finally - there has been much mention of the A B C D E F etc = settings - yet I was only able to find downloads for I and J - where can I get the presets? or do I have to keep making them up (long process) - ??

version of ptool (3.50) patch using - lpowell - reliable in camera play back patch - 35 mbs mpeg - modified to use 24p =
BTW the MPEG is better at 35 mbs then the 40mbs AVCHD in this tyoe of shooting.

FYI - You should be able to edit your posts to update info, so your three posts really only needed to be one (note that I edited this reply 2 times). :)

Regarding your desire for perfect footage, I am right there with you - however my time in this forum and doing personal experimentation has convinced me that the GH1 simply has limits and you have to learn to work with those limits. It is possible to get amazing footage with certain conditions and a good understanding of how to achieve the best results, but that can be quite the process.

Since I can't afford a better camera (like a RED or whatever), I am trying to stretch the limits of my GH1, but it can drive you crazy (as it has done to me). I will echo what other people in this forum have said before:
* Figure out the camera's strengths and weaknesses - then find various settings that work for what you are trying to accomplish (hack settings and otherwise).
* Avoid situations that cause known quality issues.
* Remember that Image Quality isn't everything. A well made video makes up for minor artifacts, a bit of mud, etc. Not many people are actually scrutinizing the pixels of your footage, most people are focused on the content instead. I am always amazed that the majority of people viewing my videos can't even see the IQ glitches unless I pause the video and point it out to them. It is just us quality freaks who are obsessed with maximum IQ that really notice. :)

And with all that said, I do wish I could find the perfect hack settings that give maximum IQ, minimal banding/mud, and won't freeze up my camera or suddenly stop in the middle of filming with read/write errors. The quest continues . . .

MJPEG should solve the banding, but then it's not possible to shoot full 1080p.

I know it's a pain : i hope to shoot MJPEG 4:3 anamorphic anytime soon, and leave the Pana AVCHD encoder altogether.

I know it's a pain : i hope to shoot MJPEG 4:3 anamorphic anytime soon, and leave the Pana AVCHD encoder altogether.

I have been loving the 80mbps MJPEG footage, but there are a few things that challenge me about it:

1> It sucks up my 8 gig SD card like nobody's business. The file sizes are simply massive. If I had more income I would buy a handful of 16 gig cards and resolve this issue, but I guess that is for down the road. :)

2> Can't view the footage in camera. I have actually gotten kind of used to this so its not a huge deal.. but it is sometimes a bit of an annoyance. :) I suppose the solution is to have a portable device that will play the footage and that has an SD card slot. I am sure something like this must exist? It might also be the solution to #1 above because then I don't need tons of SD cards (assuming I can use that same device to download the footage while reviewing it).

3> It is 30fps as opposed to 29.97fps and since I assume I should stick to 29.97 for consistency, it seems like there are some slight conversion issues? Is this rational? Probably not.. I am assuming it ends up meaning that a frame gets dropped about every 33 frames? Does this do anything noticeable?

4> Movement has a very different feel to it, and I am not sure I like it. Or maybe I do? The jury is still out, but it is noticeably different than the AVCHD footage.

5> The colors and brightness are quite different. Perhaps it uses a different gamma than AVCHD? I notice that MJPEG footage is usually brighter - not sure if that is the actual raw footage or the way FCP is displaying it?

6> No 60 fps option (which I use a lot for slow mo)

7> Only 720p (which I am actually happy with.. I haven't even used 1080p on my camera yet).


Things I love about MJPEG:

1> Crisp and beautiful footage that looks much nicer to me than AVCHD.

2> No log and transfer necessary! Although I should probably transcode it to AIC or ProRes for editing since dropping the footage directly into FCP means having to re-render all the time.

3> No mud (that I have ever seen).


Sooo... I think I am starting to convince myself that I should ditch AVCHD and really focus on MJPEG. In fact, I might re-hack my camera such that AVCHD is left as unhacked, and start pushing up the bitrate for MJPEG to its max. Then I can use AVCHD when I need long takes that don't need high image quality and use the MJPEG in tandem with an external transfer/viewing device (please tell me it exists) and go to town. :)

The other day I had to reset my firmware to remove the hack because I was doing a project that involved 10-20 minute takes (I was filming a lecture) and I kept getting card write errors (first time for the past few months). I realized that the AVCHD quality level really isn't THAT different (at least with my current 44mbps settings) to the average person and its NOT worth the possibility that an error will happen right in the middle of an important take!

Whether AVCHD is really better depends on what you're shooting. But there should be AVCHD settings that will give you an error-free experience imo. I've never had an issue with the reliable settings by lpowell. But caution is always needed as i've read stories here that definitely prove anything can go wrong at anytime :)

[QUOTE=Shawn Storm;2158662]FYI - You should be able to edit your posts to update info, so your three posts really only needed to be one (note that I edited this reply 2 times). :)

* Figure out the camera's strengths and weaknesses - then find various settings that work for what you are trying to accomplish (hack settings and otherwise).
* Avoid situations that cause known quality issues.
* Remember that Image Quality isn't everything. A well made video makes up for minor artifacts, a bit of mud, etc.

Yes - I understand - that is exactly what I was saying in my post I believe is understanding - however - what I am attracted to is the ability to shoot in low light situations with shadows and shafts of light - strangely enough the settings you shared about in mpeg - approximately 55 mbs - works much better - almost where I want to be -

additionally - using this camera for me has nothing to do with budget - it is soley the ability to have a small low light camera as a second camera that I can use all my nikon and pl mount lenses -

I will continue and get some tests up - for example some how I shot some incredible footage with one small candle as light source - it was great -

but when there are graduated areas to light and dark I get banding - and that means I have to light everything - and do the graduations in post -

that is OK too - but just trying to get the best settings for low light and high shadow shooting -

I was wondering if I could make a direct request - (GH1 - NTSC - shooting low light - areas of high shadow)
has anyone figured out settings for AVCHD 24 p - what is the highest quality - best compression - settings for AVCHD 24p
and what is the same for Mjpeg 60 p? and does anyone just have these settings as a set.ini file -

and why doesn't every just share the final firmware file?

I have found that my current MJPEG settings work good in situations with lots of shadow - BUT only if you make sure that the exposure is set properly (right at zero or slightly above). Here are the settings:

MJPEG:
E1 Quality 256
E1 Table 5
E2 Quality 220
E2 Table 5
E3 Quality 200
E3 Table 5
E4 Quality 184
E4 Table 5

NOTE: With above settings, your footage will NOT play in the camera - but you can view a still image and the final histogram (which is handy).
