No settings for this apart from the resolution / size change as was default in PTools for MJPEG.

Today I am testing new MJPEG encoder settings for improved image quality.

I have started off with these settings by CRFilms and LPowell as a basis http://www.personal-view.com/talks/discussion/comment/1762#Comment_1762

The purpose of these settings is for those with 2x stretch anamorphic lenses to get true 2.35:1 cinemascope from the GH2, rather than the more extreme 3.55:1 aspect ratio generated the lenses when used in 1080p 16:9 mode. I much prefer the less extreme cinema standard of 2.35:1 or 2.39:1, since that is what these anamorphic lenses were intended to make with 4:3 35mm film.

Today I have found MJPEG settings that seem to work well for recording quality and so sharing them here. I'll also share my further tests here. There is always room for improvement and new discoveries. The GH2 is good hardware, faster than the GH1 so who knows how high we can push it?

Rather than use 1440x1080, 1280x960 is necessary to avoid corruption, unexpected clip curtailment and enable the much higher bitrates.

Bitrate with my settings is approx. 80Mbit (variable). VLC Player reports a stream between 65,000kb and 85,000kb per second. 80,000kb is 78Mbit (http://www.google.co.uk/search?hl=en&safe=off&biw=1504&bih=877&q=80000+kb+in+megabits&aq=f&aqi=&aql=&oq=). Please correct me if I am wrong on anything technical. The footage looks great so far in this mode.

I need to do more reliability testing and see how far we can push it. Yet to find the final 'sweet-spot' but these settings are a good starting point for fellow testers.

480p Width: 1280
480p Height: 960
F1 Quality=280
F1 Table=4
F2 Quality=250
F2 Table=10
F3 Quality=225
F3 Table=24
F4 Quality=200
F4 Table=48

Lens was a LOMO 35mm 2x anamorphic in OCT18 mount.

I did not change any other settings.

A big thanks to Vitaliy and every tester, giving up valuable time for the good of the community. I salute you! - Andrew]]> http://personal-view.com/talks/discussion/1027/random-musings-shot-on-gh2-44m Sun, 25 Sep 2011 22:09:39 +0000 Greek_m43 1027@/talks/discussions

As all Pro topics it is intended to testers who want to help and understand that they are doing.
If you do not understand, either ask or just read and wait.

Active points:
* Try to format SD card using exFAT file system
* Check how it works in GH2
* Combine two large MOV files making them >2Gb, and >4Gb. Check if they can be played back in camera.]]> http://personal-view.com/talks/discussion/995/gh2-ninja Tue, 20 Sep 2011 14:53:17 +0000 djhessler 995@/talks/discussions
1. record in 24p in your gh2, connected to ninja recording
2. move your footage to your HD
3. open Adobe Media Encoder CS5 and drag a clip to it
4. VERY IMPORTANT... select clip in AMB cs5 and go to FILE, INTERPRET FOOTAGE,
5. select "Use Frame Rate from file 30.0000 (30p) Pixel Aspect stays the same
6. Field Order select "Conform to: Upper Field First" IMPORTANT
7. CLICK OK
8. now ur footage is interpreted as 30 interlaced, click on SETTINGS
9. AND render to preferred format to 23.98, I used Apple Pro Res HQ and my footage looks good.

can some of you confirm if this actually works? I know transcoding is an extra step, but doing it like this is pretty simple, specially if your on a mac like me and dont wanna go the PC route to transcode and fix the crippled HDMI footage.

Cant wait for you guys to try this out.

On a second note, I'm working on a cage specifically for the GH2, with lots of mounting options, good access to battery, hdmi, and audio input, I'll keep you guys posted as soon as I get it milled.

At the moment I'm very pleased with the Powell settings on Vitaliys awesome hack along with a 14-45 lumix and a 0.8x adaptor on a Glidecam HD-1000, and while I haven't had much low-light work it is a possibility. But I'm also keen to know whether the GH2 is as good as the GH13 (excellent!) for running shots with detailed background?

Some early samples: GH13 with 50mm Nikon 1.4 manual and 17mm 2.8 Olympus pancake http://www.youtube.com/user/BRANZmedia#p/u/1/znFMbC43GvM

and GH13 with Samyang 8mm 2.8/Olympus 17mm 2.8, plus Olympus FT-1 for shots in rain http://www.youtube.com/user/NZOrienteering#p/a/u/1/opsrj7-HoTQ

Cheers, and thanks Vitaliy for the great hack/forum!]]> http://personal-view.com/talks/discussion/290/gh2-burst-mode-tweaking-for-silent-still-shooting- Sun, 26 Jun 2011 06:01:01 +0000 lenuisible 290@/talks/discussions
Electronic shutter has some limitations, but I was wondering if having just one shot to process and a lower maximum shutter speed could help improve still quality for a "spy shooting mode".]]> http://personal-view.com/talks/discussion/954/gh2-tried-and-true-hack-settings-only Thu, 15 Sep 2011 15:38:48 +0000 mbowen84 954@/talks/discussions we can put into ptools then into our camera and have work for us.

i had this shoot last week and it consisted of 3 canon's PAL (5D and 2 7D's) ..they all shot in 1080p 25 but my GH2 was hacked and using the 44mb 24p. Because i got a card write error on 1080i and 720p 50 when using the Sandisk 45mb 16GB my only option was 24p SH, is there anyway to change the clips to 25p with cinema tools and not have a 4% speed up in audio ? or just drop it in a 25p timeline and render out ? this final will be out on DVD

http://www.dpreview.com/previews/sonyslta77/page8.asp

I downloaded the files from the link above and pulled them into streamparser. They appear to be 28 mb/sec but I noticed that their I, P, B frames were a lot lower than what I have seen for even the 32 mb/sec GH2 footage. Maybe @Cbrandin can comment on whether stream parser would be accurate for the A77 files.

The other interesting thing is that the 1080p @ 60 FPS files don't really look any better than the 1080i files. They are not of the same scene but if I didn't know which one was which I don't think I could tell them apart. Panasonic has already stated that they intend to give the GH2 25 FPS with a firmware update and they have a history of giving older cameras new features(ie: LX3 and LX5 more recently).

I think Panasonic should just enable 1080p @ 60 FPS for the GH2. They have stated that the GH3 is not coming out anytime soon. So why not give the GH2 the same features as the new A77. Panasonic has said that the GH2 is still selling well even though its price is roughly unchanged for the body only. They could charge $100 for a firmware update and give us 1080p @ 60 FPS and PAL users 25p and I guarantee it would keep the GH2 selling well into next year.

1080p @ 60 FPS is probably not as useful as we had hoped it would be. However, I wouldn't mind paying $100 to try it out.

Mr Uetmasu product developer:

A firmware update may be coming for the GH2 to add support for 25p, and additional improvements in video abilities. If there are features you want adding, contact Panasonic and let them know. They are aware of the work the “hackers” are doing and are impressed with their work, but that they (Panasonic) need to test everything / confirm there are no problems before rolling out updates. The GH3 is not due imminently, as the GH2 is still extremely popular, but that there is a high end GF series camera in the works.

Will be interesting to see what the ‘other’ video improvements are! Hopefully AF tracking and 60p.

In the meanwhile, has anyone already collected experience, what settings work well to match the look of both cameras?
Any help much apreciated.

Thanks.


P.S. Will there be a hack for the AF100 in the near future, or does it make sense to order an Atomos Samaurai for higher Bitrates?
