GH2 Settings for 720p50
  • BotvinicBotvinic
    I'm starting a new topic to individually test the 720 50p.

    Their settings, I wrote here: http://www.personal-view.com/talks/discussion/comment/16419#Comment_16419

    44M settings were such: http://www.personal-view.com/talks/discussion/comment/14632#Comment_14632
    They do not work, but work on GOP24, 32M, AQ2

    720 60p stably works on driftwood "Beautiful buffers" to 55M GOP12 AQ2-4. But not working at 50p.

    There is a want to test 50p? Ptool 3.62D long time ago, but nobody tested it?

    Here is the new answer from @driftwood:

    so guys, did anyone manage to make driftwood's "Beautiful buffers" work in 720p50? Thank you!
  • PavezerPavezer
    Yes, compressor works ok in terms of pixel quality. But.. It's color shift from MTS to mov is absolutely ridiculous :) Skin jumps from natural into piggy red. I found out that there's no solution inside Compressor, but if you rewrap first to mov using Clipwrap and then convert the wrapped mov to true 25fps ProRes inside Compressor (automatic gamma off and preserve source color) colors are fine.

    This seems a bit "handicapped" workflow, but that's the only way I got acceptable 25p720 ProRes clips using ticked 25p patch (this is using a Mac). Clipwrap is pretty fast, so I don't think this extra wrapping is much of a problem.

    Still, I really really really would like to have a 25p solution from you Panny, thank you. ;)
  • RRRRRRRR
    Pavezer: I tried around with a lot of different software, Handbrake was the only converter that allowed for reasonable quality conversion (although several converters managed to understand the footage correctly), yet when pixel-peeping there was a clear loss in quality (I just had to get a working clip at the time). Good to know that compressor can handle it! (propably better than Handbrake!) I didn't have it installed at the time, and suffice to say that I don't use the patch any more! Downconverting "true" 50 fps to normal 25fps is easier - imo.
  • PavezerPavezer
    After some further testing, I found out that "false" 25fps is convertable to true 25fps ProRes with perfect audio sync in Apple Compressor. You just have to go to Inspector -> Frame Control tag -> check the Frame Controls on and change Retiming Control's 'Set Duration' to '50%'.
  • PavezerPavezer
    @RRRR Well, yes I do understand that it doesn't make true 25fps, but the fact that most converters do funny tricks with slomo makes me wonder.. Are you saying that you are not able to make it work with converters as 25fps even if it was 50fps in the beginning? I have played around only with "false" 25fps.
  • RRRRRRRR
    Pavezer: it doesn't make it a true 25fps clip. Hence the trouble converting it. I had the same issues when I tried it and had to look all over for software that could convert the mts files so that I could import them in proper speed to premiere.. If you want 25fps you might as well record 50 and make it 25 in post.

    Is there anyone who have been working on getting the most out of 720p50?
    I find this setting quite strange.. is there some kind of interlacing going on when recording it?
    On some anamorphic footage using 720p50 it looks kind of interlaced..
    It would be really nice if an effort was made to make 720p50 more useful!
    Maybe there already is some good settings for this that I've overlooked?
  • PavezerPavezer
    @alcompomposer
    Yes, mac+fcp. Haven't tried fcp conversion yet. I will test that and I'll make other test too, I'm interested in why this happens and if there is general solution. Not willing (or possible) to do fcp conversion every time.
  • alcomposeralcomposer
    @Pavezer
    Have you tried using the conversion inside of FCP? (if you are a Mac+FCP user that is)
  • PavezerPavezer
    I shot clips 720p50 using checked Ptools 25fps tickbox to get 25fps material. Looks great, but...

    MTS clips are recognized as 25fps (VideoSpec, VLC, and Quicktime) and they look fine with Quicktime and VLC players, but when I try to convert them to 25fps ProRes, the video is slowed down to double and audio stays at normal speed. Tried 5DtoRGB, MPEGstreamclip and Clipwrap with all the possible settings available. Same situation: video is handled as slowmo and audio is fine. Only software which worked as expected (output video and audio is fine) is Aunsoft MTS converter. Unfortunately, quality of Aunsoft isn't as good as the other converters..

    It looks like converters can't handle the footage as 25fps. How come and any solutions?
  • BotvinicBotvinic
    Variable, how it is? On a static scene? Show report StreamParser.
  • actact
    @botvinic
    Your last posted setting makes variable bitrate. Just now checked it.
    I would like to find similar stable settings but with maximum constant bitrate for sure long recordings on not too fast SDXC card like Transcend 64Gb (25MB/s)
  • PavezerPavezer
    Hey guys, a long time follwer here. First post.
    First of all, I have to say that the work for GH2 hacking is unbelievable. Thank you everyone, especially Vitaly.

    I'm shooting a 25fps project during the weekend and I'm willing to find the best stable hack settings or .ini for 720p50 at the moment. I'm using 16GB trancend class 10 card and have to shoot clips around 20-30 mins duration, audio required.

    OR is there any great 1080i50 settings i should consider?

    I tried to find the best info from the topics, but the amount of posts is sooooo massive that.. I just have to ask. :)

    Thanks a lot in advance!
  • driftwooddriftwood
    @Botvinic Ill take a look.
  • BotvinicBotvinic
    @driftwood
    You can do two firmware?

    1. 720p 50 Mb 24 Gop, AQ2.
    2. 720p 50 Mb 12 Gop, AQ2

    Specially for me. If the first will be with artifacts, then my card was not guilty. My Settings 50Mb Gop 24, AQ2 work fine!
  • BotvinicBotvinic
    Okay, so I have a bad memory card ...
  • paglezpaglez
    I have Sandisk Extreme 45 Mbits an I'm not getting artifacts
  • BotvinicBotvinic
    You have SanDisk Extreme? What speed?
  • driftwooddriftwood
    I'm not getting atrefacts with my GOP1 stuff!
  • BotvinicBotvinic
    I wrote that it is setting my friend. I have not changed them, I do not understand them ... but with them no artifacts!

    September 26 - 50p 40 Mbps, 1080p AQ3
    September 27 - 50p 50 Mbps, 1080p AQ2 (more stability)

    No more differences

    Again, I do not understand you? :)
  • driftwooddriftwood
    @Botvinic re: your 50M setting. I dont think you need to use Video bitrate 24ADD at all. What made you mess with the muxer buffers? I messed with them but found little difference.
  • driftwooddriftwood
    @Botvinic your setj file, is this the same as the 26th sep posting?
  • BotvinicBotvinic
    No, this is what I use now. And they work on my card without artifacts at 50p.
  • driftwooddriftwood
    @Botvinic what do you mean? Youre sending me a setting to adjust?
  • BotvinicBotvinic
    @jackcklam
    Read all the messages. There are some stable firmware for 720 50p. Here's my latest setup. Test!

    @driftwood
    Setting the buffers did not help. Has helped GOP24 :((( But now you can set the bitrate to 50Mb.
