Andrew, I am in the process of testing many variations now. I hope to be able to create an AppImage later today for user to test also. Thanks, Phyllis On Mon, Jun 14, 2021 at 11:41 AM Andrew Randrianasulu via Cin < [email protected]> wrote:
See updated patch.
I tried few more fps choices - some work, but say 72/144 fps still do not work with mpeg2 .. :/

Ah, no - 23.97 and 59.94 fps/mpeg2 were broken!
But with attached patch the seems to work again, as well as 100 fps mp4/x264 encoding (also tried mov)
Can you test as much as possible various (long!) films / videos for desync problem?
I also can try and add few more fps choices in this menu...

Hello,
I cannot seem to figure out how to render video over 60FPS.
Yes, i can confirm this bug.. Just set project/timeline to 100 fps and got this.. After inspecting cinelerram/ffmpeg.C I tried few things, but working one was just replacing this check_framerate function with std. function from libavcodec:
https://ffmpeg.org/doxygen/3.2/group__lavu__math__rational.html#ga7dfd5ba1eb...
AVRational FFMPEG::to_sample_aspect_ratio(Asset *asset) @@ -2917,7 +2919,8 @@ int FFMPEG::open_encoder(const char *type, const char *spec) int mask_h = (1<<desc->log2_chroma_h)-1; ctx->height = (vid->height+mask_h) & ~mask_h; ctx->sample_aspect_ratio = to_sample_aspect_ratio(asset); - AVRational frame_rate = check_frame_rate(codec->supported_framerates, vid->frame_rate); + //AVRational frame_rate = check_frame_rate(codec->supported_framerates, vid->frame_rate); + AVRational frame_rate = av_d2q(vid->frame_rate, 1000); if( !frame_rate.num || !frame_rate.den ) { eprintf(_("check_frame_rate failed %s\n"), filename); ret = 1; I tested 29.97 encoding and 100 and 1000 fps encoding - they come out correctly, according to ffprobe/mediainfo.
Not sure why such strange convolved method of checking framerate was choosen... Only mpeg1/2 in ffmpeg-4.4 set those .supported->framerates arrays.. (grep supported_framerates libavcodec/*.c)
$ grep supported_framerates thirdparty/ffmpeg-4.4/libavcodec/*.c thirdparty/ffmpeg-4.4/libavcodec/mpeg12enc.c: .supported_framerates = ff_mpeg12_frame_rate_tab + 1, thirdparty/ffmpeg-4.4/libavcodec/mpeg12enc.c: .supported_framerates = ff_mpeg2_frame_rate_tab, $
In theory this fix should also 'fix' high-fps proxies with mpeg2 (non-standart stream, but only ffmpeg supposed to read it..) Just checked ffmpeg/mpeg type and it works....
I can do 60 FPS and below with no issue. Everything is rock solid stable and very performant.
I am using Cin gg latest on Ubuntu.
My source video is 2560x1440 at 90FPS.
What I've been doing: - start new project - Settings -> Format, manually type 90.000 in "Frame Rate". Ensure that 2560 and 1440 are in Width and Height accordingly. Then I click apply, then click OK. - load my file through resources. right click on thumb of my video in resources, and choose "match all".
Then when I render my project with "File Format" of "FFMPEG" and "type" of "mp4" I get these error message windows/errors:
One error window with: ------------ "Couldn't open /path/to/outfile.mp4" ------------
and another window titled "Cinelerra: Messages" with this in it: -------------- int FFMPEG:open_encoder(const char*, const char*): check_frame_rate failed /path/to/outfile.mp4 ---------
Am I doing something wrong?
Thank you in advance.
