I use the same settings voor the Quicktime format, so with the MPEG4-Video codec.
As said, the HDX100 network media tank does not handle it well. Playing the mov file back with a video player like vlc on my PC goes flawless.
Now the footage files in my timeline (m2t, derived from MTS which is JVC AVCHD format) are different from the kind I used in previous projects (mpg, derived from tod, which is JVC MPEG-2 TS format), using the command:
ffmepg -i name.tod -acodec copy -vcodec copy name.mpg
So I tried to render a previous project as UYV4MPEG Stream with:
mpeg2enc --multi-thread 8 --verbose 0 --aspect 3 --format 3 --frame-rate 3 --video-bitrate 28000 --nonvideo-bitrate 384 --interlace-mode 0 --force-b-b-p --video-buffer 448 --video-norm p --keep-hf --no-constraints --sequence-header-every-gop --min-gop-size 6 --max-gop-size 6 -o %
This had worked in the past. But now, the same problems arises!
++ WARN: [mpeg2enc] Progressive encoding selected with interlaced input!
++ WARN: [mpeg2enc] (This will damage the chroma channels.)
**ERROR: [mpeg2enc] Rate control can't cope with a video buffer smaller 4 frame intervals
The problem does not seem to arise from the footage.
Could it be that cinelerra has been upgraded to 2.1.5CV or something has changed with the mpeg2enc?

for HD final rendering I use MPEG-4 codec with quicktime (.mov) format. But I should add that I work in 1280x720p for HD.
I assume that the original capture video OK?

I am trying to render a movie with lots of m2t HD footage, converted from MTS (from a JVC Everio GZ-HD30E camcorder) by this command:
ffmpeg -i name.MTS -r 25 -acodec mp2 -vcodec mpeg2video -ab 384k -b 34000k -f mpegts -y name.m2t
I can render to quicktime format (*.mov) but my HDX100 media network tank, trying to play it, will start to behave strangely after some time, loosing sync or even audio, going into some slow motion mode. In other word: useless.
So I tried to render to a UYV4MPEG Stream with pipe mpeng2enc:
trying popen(mpeg2enc --multi-thread 8 --verbose 0 --aspect 3 --format 3 --frame-rate 3 --video-bitrate 28000 --nonvideo-bitrate 384 --interlace-mode 0 --force-b-b-p --video-buffer 448 --video-norm p --keep-hf --no-constraints --sequence-header-every-gop --min-gop-size 6 --max-gop-size 6 -o /data2//Madeira/test1.m2v)
The rendering aborts directly giving this errors:
++ WARN: [mpeg2enc] Progressive encoding selected with interlaced input!
++ WARN: [mpeg2enc] (This will damage the chroma channels.)
**ERROR: [mpeg2enc] Rate control can't cope with a video buffer smaller 4 frame intervals
Anyone knows what's going on here?
