"I think you can probably shut down lens correction by going to "SHOOT W/O LENS" and setting this to "ON". Panasonic lenses will still work."

Does nothing to stop these errors. Shoot wo lens doesn't stop any of the panasonic lens's functionality as far as I've experienced. I've always had it set to on. I don't know if it turns on and off lens correction. Or if that has anything whatsoever to do with the errors.

That first test was around 1min ~1GB.

Now I've tried the same torture on 720p60 and gave up at around 5:30s (because I believed it should have already spanned) but the file ended up short of 3.5GB. Not only that but my shaking abilities have been seriously challenged because the report shows much less bitrate:

File: A:\PRIVATE\AVCHD\BDMV\STREAM\00002.MTS

Size = 3.553.880.064 Bytes (18.509.792 Packets)

Stream: Max Speed = 85.509.280 bps

Mode = 720/50p

PCR Timing Interval = 0,095 seconds

Clip Time = 0:05:45,72

Average Total Bitrate = 82.237.187

Average Video Bitrate = -19.813.054

Average Audio Bitrate = 235.005

Average Other Bitrate = 2.429.206

Max GOP Size = 721.152 Bytes (5.769.216 bits)

I don't know if this is due to the nature of 720p or if the use of P-frames is helping (still I'm not buying it because they are very marginally smaller than the I-frames)

Thanks again.

@cinepaint, ISO 1250 may be problematic if you don't know about the discussion here:

Otherwise, please post a frame and someone may have some feedback that may assist you. Regards, WR

Hey everybody! Id like to show you what I was able to do with the Aquamotion patch. The driving scenes were shot with 24L toned down to 66mbps. The rest are shot with the 24H 100mbps mode. I know its a little behind but I just wanted you guys to check it out and if possible pass me some tips on how to utilize the hacks better. Now I am trying the Terraquake patch with 24H toned down to 132mbps and 24L down to 100mbps just because my card can handle those bitrates better. Thanks again and I hope that you guys can give me any type of criticism to help me out.

@driftwood : You're probably right, the video bitrate was stable and well above 80Mbps.

@artiswar And the lenses i used were the Lumix 14mm 2.5 and the Sigma 24-70 Canon mount with the kipon adapter.

Can you try the file that produced the integer error with the newest version of StreamParser (available in the StreamParser thread near the end)? If there is an overflow problem then I would like to fix it, but I may have already.

Sorry @cbrandin, I binned the files shortly after the test. :( I can't even remember the disk they were in to try an undelete)...

@driftwood: I'm on a timelapse AVCHD vs MJPEG quest now and I've got some unusual findings:

The MJPEG 2048x864 resolution is much superior to 2160x810 (this one looks like garbage, I even thought that AVIDEMUX didn'tunderstand it, but then I tried 1920x1080 and even though its also skewed, it's also much better)

MJPEG 2048x864 even beats AVCHD FHD 1920p1080 in horizontal resolution by a whisker. Check it out.

I'll be exploring it for timelapses but it eats bitrate like the devil, so I'll have to short it to 2fps and tone the bitrate down because I'm not very found of the idea of sacrificing one of the AVCHD modes instead... :(

is Quantum 100 the replacement for Aquamotion2?

Well, I though it might be a good idea to test MJPEG for 2304x1152 (it's a 2:1 horizontal bin and a 3:1 vertical) but besides having speed problems (it bails out at 5s) the output is as bad as was 1080p or 2160x810... Back to 2048x864... @driftwood How did you get to that magical resolution? I mean I know 2048 is magical but 864???

@duartix On the GH2, 2048x864 is a 1.33x anamorphic aspect ratio, and will produce 2.37:1 widescreen videos with square pixels when used with a 1.33x anamorphic adapter. This is the widest anamorphic frame that fits within the 2K DCI standard, which defines a 2048x1080 frame. It can also be cropped down to a 1920-wide frame for Blu-ray compatibility.
