MJPEG 70mbits+ 1080p settings

I've read the whole thread but i'm still not sure whats the best mode.. :P
so pappas are you recommending 1280x1080 DVCPROHD mode or the 720p/30 mode? also i'd like to know if you can change the box 'MJPEG Encoder 30fps->Xfps' to 50fps (pal version) or would this couse writing errors ?
sorry for my bad english ;)
 
BTW, what is going on when choosing H or L AVCHD in the camera? (the steps are FHD, SH, H, L)

From my tests its a little different from SH now, after the patch, so I guess they are also using the values of the AVCHD with some multiply values...

It will be good idea to find this multiply values and patch them so one can have option to have "low quality" setting to simple stuff that don't need top quality.
 
I done some tests tonight, with the settings of this thread for MPEG, when panning fast there are jumps in the video, same condition with C setting AVCHD native off, smooth panning.
 
I'm a big fan of the MJPEG codec and I've been working to get it to perform reliably on my GH1. I'm now upgrading cards to a Sandisk Class 10, hoping that will allow me to get 1440 X 1080 to work-- I really like that size and codec because it seems to both soften things (like grid noise) but also give a very rich image. I think I like it best with film mode: Nostalgic -2 contrast -2 shardpening and -2 NR, because it looks the most like s16mm. I haven't yet been able to get it to perform reliably-- especially when using a Panasonic auto lens (the 7mm-14mm which is great by the way). I'm hoping the new card makes the difference.

It seems like this thread has been abandoned, and not many people talking about MJPEG anymore... anyone still working with these settings?

I see that Pappas hasn't updated the first page yet for the new version.

I believe now there are only two boxes to check-- the width and heighth of the MJPEG-- and no longer the third box: MJPEG SIZE 1280m - SELECT--- unless I'm wrong and the field labeled 720p30 -> 1080p30 still needs to be checked?

At 720p I have had fairly good success with these other settings posted:

Q1=400, T1 = 4
Q2=300, T2 = 4
Q3=250, T3 = 4
Q4=188, T3 = 4

Although again, when the camera is especially taxed with auto functions it can fail (on a class 6 card anyway).

Anyone else still working with MJPEG out there?
 
If only we could get 25p out of MJPEG - 30FPS is killer in PAL countries.

Ryan, use TMPGenc 4.0 to convert to 25fps, it does a fantastic conversion that cuts into my other 25p footage flawlessly.

What specific issues are you having??

I do...heck I even convert my 1080P avchds to 44mbps mjpeg to improve editing stability (Xilisoft converter ultimate 6...very good for this).
I have used modulr's settings and Pappasarts settings and blown away by the image quality (suck it 7d lol)...however sometimes even with my class 10 sandisk gave me one or two write errors recently while shooting a wedding (NOT GOOD!).
After a bit of searching Ive found these settings give me 50mb 100% stable mjpeg and in all honesty the image quality is pretty much the same as the 70mb (maybe a bit overkill with 70mb)

Quality settings (E1 to E4) - 352, 220, 200, 184
Table settings (E1 to E4) - 24, 24, 24, 24

1080 mjpeg give me write errors even with lowbitrate...so I use the 1440 which is super stable and looks great!
I do not use 4.2.2 colour..it makes things worse in my opinion!
Now only of there was progress on it to at least make it 25p (as im a brit)
 
Thank you for that. I'll try these out. It would certainly be nice to get a few more minutes of 2gb recording with similar quality. When setting the 1440 X 1080 size up with the new Ptools, do you leave the mjpeg size box "1280=>1920" blank? And then put your size changes in the other two boxes width and heigth? I only ask because I remember in the older versions you first had to check "1280=>" and then also the other two boxes.
 
Hi
i just tried method #3
it is amazing!!!
thanks a lot Pappas and of course Vitally (tester13)

i could only record 3.5min then checked the file size. it was 1.9GB

my question:
is there a limit on recording time because of FAT32?
no spanning?
 
Hello Pappas,

How do you quick convert 1440 to 1920 either in QT or better yet in the GH1 itself? Is there a setting in QT that you can check? I tried messing with visual settings under properties in QT but couldn't make it work. Thanks for giving me options. Bill
 
Hello Pappas,

BTW...I can't get the GH1 to play anything but:
E1 Quality=150
E1 Table=86
E2 Quality=130
E2 Table=56
E3 Quality=115
E3 Table=26
E4 Quality=100
E4 Table=4

It won't play your standard:
Quality settings (E1 to E4) - 352, 220, 200, 184
Table settings (E1 to E4) - 24, 24, 24, 24

I am using an ADATA class 10 card.
I've used my ADATA class 6 perfectly for un-hacked GH1.

To be clear, the files play fine in QT just not the cam.

Do you have any other lower-end settings besides the above set listed that work on playback within the camera?

Thanks for your input.

Bill
 
Are we no longer able to change to a 1440x1080 frame size? I can't find options in the Ptool v3.5 to pull this off. Also, the only 1080p settings are to upscale 720p...I feel like I am completely missing something.
 
You can set MJPEG to 1440 width and 1080 height in the MJPEG settings, just as my Anamorphic Patch set 1920 width and 810 height.

However, I think a frame with 1920 horizontal resolution produces better looking results than a frame with 1080 vertical resolution. Our eyes are designed with binocular vision to be more sensitive in horizontal discrimination, and relatively less sensitive to vertical resolution. That's why interlaced video doesn't usually look as terrible as it actually is.
 
Thanks for the tip lpowell...idk why I didn't just assume that right away. Vertical vs horizontal huh? I hear a shootout in the near future :-)
 
I just tried the QUALITY SETTINGS [ 384, 330, 300, 276 ] TABLE SETTINGS [ 24, 24, 24, 24 ] for 720/30p and the results were very good. I was shooting trees and bushes at 1/60 on a windy day and getting a phenomenal average bitrate of 74 according to my bitrate viewer with no recording failures on my 8gb scandisk class 10. The colors and saturation on my nikon 50mm 1.8 have never looked better. I just may be an mjpeg convert. The depth of color looks really, really good and reminds me of my old kodachrome days.

Hey Robert, I haven't looked at this thread in while, and missed these posts. Yeah the mpeg mode is awesome. Nikon 50mm is always a nice lens...

Implementation of Pappas Settings - Help Needed

Implementation of Pappas Settings - Help Needed

I have read each and every page of this thread but I admit to being at a loss as to how to apply page 1 settings. There are versions of Ptool no longer available, there are settings mentioned that no longer exist in Ptool 3.51d (MJPEG 1280p width,MJPEG 1280p height,MJPEG SIZE 1280m) and there are settings mentioned by some appliers that seem to be part of this patch but aren't on page one (buffer sizes, etc.).
I've attached a .ini (as the required .txt) that represents my translation of all this into Ptool 3.51d and firmware 1.32. I used the parms from Method 3 (unnamed, last method). I would greatly appreciate corrections in order to achieve the great results of this patch. (The .ini uses 4:2:2 as its "default"). Thanks.
P.S. Although posted in its own thread, no action. So, is it possible to combine Pappas #3 with lpowell 75 Mbps Hi performance patch, i.e. essentially replace the quality/table values of it with the Pappas values? Note this question is a logical follow on to the above, i.e. are there values (e.g. bitrate, GOPs) that could conflict taking this approach?

Hi Jordell,

I can understand your frustration. Ptool has changed many times - causing this issue with old directions not current anymore. Obviously bit rate settings/gop don't relate to the Mpeg mode like they do with AVCHD. Later I will try to look at the new Ptool and see if there is a way to update the settings.

As to the #3 settings- I assume your referring to the 720P 80mbit setting. This is one of the best of the Mpeg. It's very stable.
This was a blowup test from this setting http://www.dvxuser.com/V6/showthrea...stills-amp-comparisons.&p=2009705#post2009705
