There are definately differences, especially over the 244M patch.
It's definately due to compression levels. I can also see that Quantum v2 appears to offer less compression especially looking at the back wall.

Thanks @FGCU for the excellent test!

thank you FGCU , do you also have playback on your gh2 with all those patches? or playback works only on lower bitrates hacks? i would like to buy gh2 as soon as i can and i would like to know if all those patches are playable or i must buy also an external monitor to check my footage.

Hi! can i ask somebody, do all those stunning gh2 patches allow in camera playback? (i´m gh1 user only) if not, which of them have problems with playback? would an external hdmi monitor solve the playback problem?

@FGCU, what differences are you seeing between in those screen shots between Quantum V2 and Seaquake v2? To be honest I can only spot some tiny differences, none of which I would necessarily attribute to compression.

I still need to do my own tests for Driftwood.

@FGCU doubt it but you never know its gonna be interesting to see how far we can push mjpeg.

No I already know seaquake is better at L. Test against H if you like for me :-)

Please understand, Quantum L setting ( a much lower bitrate but based on a high limiter) is like the AQuamotion/SpanMyGopUp patches' H bitrate setting - ie lower i frame quality (but still good quality) - we're trying to combine the best of both worlds - High quality setting (which won't span on most cards) because of the high bitrate / plus a decent quality L setting for spanning/long recording work.

Or possibly a 1920x810 patch for everyone who has a 1.33X anamorphic lens. I purchased a Century Optics adapter from LPowell a month ago and love it.

I'm sure a seaQuake MJPEG deviant would do the widescreen users justice (of course if those settings are possible outside of AVCHD)!

For now, in my opinion, GH2 Mjpeg codec -in HD size- is in a very preliminary phase ("MJPEG is in its infancy " Sir Driftwood said)

@Driftwood
Do you think that you'll be able to get similar clean images in Mjpeg than Avchd? I guess that MJPEG codec efficiency never will get avchd quality .

@pchristoph Hi mate, try 'Quantum' BETA 2 and test the L setting - should be very close to spanmygopup/AQuamotion2. I'm still fine tuning the setting and will probably tune it till it reaches slightly better quality than AQuamotion v2 and at AQ4!
The H setting should in theory be better than seAQuake but needs testing. Looks better to me on streameye macroblocks, but all situations need testing.
Hope youre well & good, Nick :-)

@jfro I'll try and answer both your thread comments:
1/ 1080p24 H and L are both INTRA GOP1 - sorry (better than GOP3).
2/ 56000000 should work without underflows / overflows on the L setting only. Keep the H setting high if you try a very low bitrate on the H it will fail / produce poor i frames.
3/ extended times: Yes, go ahead and try changing GOP1 to GOP3 but you'll get very high P frames - the saving will be neglible on H setting, but better on L setting. ;-)
4/ P frames predict to the next i frame, B frames can predict backwards and forwards and are lower than in size than P frames. To achieve B frames, turn encoder setting 1 = default (not 2). Driftwood Hi quality GOP3 patches have already been made in the past using P and B frames and can be found on one of the low gop threads (some time ago!) you could always adjust those!
5/ Test all settings and check graphs with Streamparser (look for cadence issues where the graph goes strange) and test on the various death charts like Pappas/sStray's colour chart discussed throughout these threads (use search)

Hope that helps you. :-)

Nick

@FGCU
1/ No - the 'L' Cinema 1080p24 setting is lowered bitrate GOP1 to around the quality of the AQuamotion/SpanMyGopUp - to enable spanning and long recording. This was confirmed as a working possibility by @balazer and so far it looks good without underruns / overflows. So thanks to him.
2/ The H setting is still the hi quality of seaquake adjusted (with new encoder settings) to run AQ4 (seaquake was AQ3). We need to see which one is best so report back your findings.
3/ To access MJPEG mode, goto 'Creative Mode' and 'OK' then go to REC MODE and 'OK' the bottom setting 'Motion JPEG'. Then goto 'REC QUALITY' where you'll find 4 modes. HD mode = Reference 2K (2048 x 1152) and VGA Mode = 2K container (2048 x 1080). The other two settings in 'REC MODE' can't be touched by ptools so are irrelevant.

Hope this helps. :-)

@driftwood, I'm a PC, but I looked at that software. It seems like it would only convert the container for AVCHD to Quicktime. How would this affect the clip frame rate (60i -> 30p)?
