GF2 Stable Settings

    @pdlumina I too like to use the settings for anamorphic. I got a 2x anamorphic adapter and would like to try it out. Is there a way that you can share your settings?

    Also, is there a way to combine the settings or should it just one setting to choose?

  • stoneystoney

    @pvdog your setting deserves its own thread if you can maintain the settings like... stabilizing 720p playback :)

    I know it works on GF3. It might work on G3 and GX1, too.

  • fehafeha

    @pvdog

    Great, it is very smooth in panning and motion ... For my self I removed all except for PAL 1080 ... here is ini, @pvdog let me know if I did correct or ? Also i removed all related to 720 and mjpg for now ...

    I don't have a GH2; so I cannot test it but my patch should work straight on GH2, at least for 1080i and 720p. You only need to add 24p settings, should be easy.

    My patch is similar to Cake, without narrow bitrate limits and with good B frames. I can understand why Cake does not use B, but I cannot understand why it uses very narrow bitrate limits and fallback, I think those are much worse than using (good) B.

    As Adobe explained well in its Flash development guide, B is important for motion details. The stock B is coarser, that's why we did not want to use it. Thanking to LPowell, now we know how to make P, B and fallback good, then why not use all them including B? Plus Balazer's discovery about GOP tables, these two are the most revolutions in this video hack game, other patches are more for fun not for serious work. My patch combines the virtues of these two plus my own tweaks.

    As my patch uses same GOP size (6), it should work for GF3 too.

    I'll make 720p play in camera in another version, should be fairly easy. I thought quality was the most important; so I made it the most optimal as long as it was absolutely stable.

    Although I'm new to this game, I knew GH13 since its first day but GH1 was too big to my like and GF1 lacks of ETC, so I waited to join this hacking game till GF2 available recently. But I know how to do such things right (I'm a top audio guy, for example). I think my patch deserves its own thread like Cake, Flow Motion etc.

  • fehafeha

    @pvdog , tested Cake 2.0 , but your settings gives more smooth motion. It would be great to make a stable play in camera for 720p ...

  • stoneystoney

    As @rambo pointed it out, 720p mode supports ETC 3.9x where 1080i doesn't. It would be nice to have stable 720p in-camera playback.

  • pdluminapdlumina

    @pvdog your 1080i NTSC settings are pretty stable and healthy-looking. I will use them as template and erase-discard the 720 AVC settings since I never use them anyway. Also I will change the Motion JPEG size to anamorphic for higher quality (same bitrate in less area, similar to DVCHD Pro)

    @pvdog any plan to make 66Mbps GOP6 settings for GH2?

  • fehafeha

    I tested even with Cake 2.0 and works great ... (same i use on GH2) ... if used Film mode Standard -2,-2,-2,-2 on GH2 the footage contrast/colors is similar (if used GF2 as B camera ...)

    @pvdog , playback in camera is important, if you could reduce a bit rate in 720 it might get stable. I like the colors and contrast of your settings, similar to Vibrant in GH2 :-)

  • RamboRambo

    Credit were credits due, pvdog, looks like you have sorted the issues with PAL, both 720p and 1080i look very nice quality, very clean, and are stable on my class 6 Transcend 16gb card even with 720p in ETC. 1080i plays back in cam, but not 720.

    Actually i find the colors muted a little more but very well balanced, this is good, an easy bump in post without having to try juggling colors. Bitrates varied from 29mbps to 45mbps, motion looked smooth. These settings are now staying on my GF2 till the manual control is available in the next ptools. Thank you.

  • AndySAndyS

    OK - thx. I hope to give it another try with the new version. Great that Stonebat likes it. Well done.

  • pvdogpvdog

    I don't care about the shadows, the first thing about GF2 is to get the video look good enough. My patch looks more contrasty, or darker might look even darker. Also, what I care mostly is 1080i not 720p; that said, 720p is not bad at all, I just did not test them as much as I did with 1080i.

    Although I frames are not very very tall, but keep in mind: P and B frames are no longer coarser than I.

  • AndySAndyS

    Stonebat, anyone? Does the detail in the shadows seem to be a clear improvement over Stock?

  • AndySAndyS

    PVDOG - what about detail in the shadows? Is it a clear improvement over Stock?

  • stoneystoney

    @pvdog your settings gave almost 48Mbps on death chart stressing test. 672KB ave I-frame size. Good good!!

    Not sure if it's just a coincidence. Yes it gave more contrast and saturation, too. Yes I like that way better. Finally I'm switching from the 32Mbps to this new settings. Kudos to @pvdog and everyone.

  • AndySAndyS

    Thanks. Could be worth a try.

  • pvdogpvdog

    Both NTSC and PAL work fine here, smooth and no failure yet.

  • JayB38JayB38

    Thanks @pvdog. I'll check it out.

  • AndySAndyS

    I was testing PVDOG's on PAL yesterday and it almost froze my new camera. Was pretty worried. Don't know whether to try the new .INI or not. Is it fixed on PAL now?

  • EbachervilleEbacherville

    Just applied pvdogs patch "setf", looks good.. even recorded on a 3-4 year old slow 1gb SD card just fine.. filled it up quick as heck, but worked great :) Details looked good, surprised me when I shot a old computer monitor and could see dust particles on the screen.. Have to wait for some daylight to test this outside. Have to add NTSC here , didn't test PAL

  • pvdogpvdog

    Although 720p and 1080i generate the same file size, about 5MB per second, the former is reported with a double bitrate (90mbps vs. 45mbps) by GH13 Stream Parser, I guess too high to play in the camera. 1080i plays fine in camera.

  • fehafeha

    OK, i got read error in camera play 720p ... I went for Cluster v.1 and it works ok on GF2, got over 40 mbit/s ... Will check in day light ...

  • pvdogpvdog

    I use the default P mode, not any those color modes because they all look childish.

    44mbps is the actual average bitrate, it varies from 41m to 45m (maybe 50m). This is the best I can get for absolutely stability and 4GB spanning, after playing numerous times with GOP tables. I just tested that 4GB spanning is fine with a class-4 card on 1080i50. For 1080i60 at least class-6 is required for 4GB spanning.

  • stoneystoney

    @pvdog why not 48Mbps? :)

    I like a simple multiplier. 16 * 3 = 48

  • fehafeha

    @pvdog thank you very much. I'm testing it now ... What color mode to use or it does not matter ?
