Stable MJPEG and AVCHD settings

thanks a lot man.......i really appreciate the help.......one question though.......are those stable settings for my sandisk card @ 30mbs?.......I ask because i saw other settings at higher bitrates......I just want to make sure im maximizing my settings so i can start filming.......also....4:2:2 is critical because i am a vfx student and shoot alot of greenscreen
 
losing motivation

losing motivation

I pretty much get what I have to do now.......but I'll be honest.......I losing motivation due to all the different settings......lack of monitoring.....wack auto gain control......and just no real solid settings.......I love the idea.....but I'm starting to think I should have just spent the extra $$$$$ on a 7d and been done with it.....arrrrrrrrgh........back to bh the gh1 may go.......might not make it to the gh13......cause the footage is crappy without the mod........and stills blow @#$%$#

Back to the 7D with even worse auto gain control, color chroma aliasing, and lower resolution. Just saying, neither is a perfect solution.
 
I'm just frustrated........I understand what the camera is capable of.....I bought the fastest card available.....I just thought I would have a more concrete setup.....I love the idea.......but not so much the process.......Ive modded everything I've ever owned(xbox,xbox360,ps3linux,iphones,nexus one.....etc)....I dont expect it to be flawless.......just more card specific I guess.....one person say one thing.....then another says another.....all having different cards and brands........if testing is to be done with some accuracy then it should be card based with exception to lenses.........probablt why panny crippled the codec......which was lazy on their part.......and of course they didnt want to interfere with ag100 sales....lol

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.
 
Modifed setting.
Still stable. Shooting charts with no issue. I get around 29mbps in high detail and 19-20 in low detail.

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.

understand what you feel ...feel the same sometimes even get 15mbps way below the standard minimum then change settings and goes back up again.Its a long wait and can be addictive...often times time consuming...but I think it is the idea of the nirvana, like a treasure hunt.... its a kind of a rush....and that my friend you do not get with a 7D.The hack has gotten into our psyche...its not the settings or the bit rate, its defying and getting one over the system.We are all rebels in our mind and its the only time we feel empowered by managing an open platform given by this russian genius...or is he ukranian?

Try grass. I shot charts several times with no problem. Static grass 5 seconds and freeze. Static grass is the true test.
 
E1 to E4 Quality settings why 4 different ones?

E1 to E4 Quality settings why 4 different ones?

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...

scan difference between AVCHD and MJPEG

scan difference between AVCHD and MJPEG

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?

Mate you have way too many patches selected to even begin trying to analyze that. Try going back to just basic c settings and add the conversion patches one at a time for comparison.

I have seen that also. Please start another thread for this topic. Thanks.
 
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?

Use these settings- and you'll get excellent quality..

BTW- It's good to see people still using the MJPEG mode- it's very clean and if we can get 24fps in MJPEG- WOW!

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:

I used the setting and it runs fine but it stops recording at 3:40. Any clue why it's doing that?
