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?

Hello, anyone out there?
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?
