Subject: Mjpegtools problems
Can anyone offer advice?
I get this error which doesn't seem right:
**ERROR: [mpeg2enc] display_horizontal_size must be in range
0...16383
This doesn't seem right because the man page says the range can be to
38363.
I'm trying to convert video files from my Canon 7D, so they can be
edited in Cinelerra. Here is the code I'm using:
ffmpeg -i $ORIGINAL -vcodec ffvhuff -s 1920x1088 -threads 8 -f
yuv4mpegpipe - | mpeg2enc --multi-thread 8 --verbose 0 --aspect
3 --format 13 --frame-rate 5 --video-bitrate 24000
--nonvideo-bitrate 384 --interlace-mode 0 --force-b-b-p
--video-buffer 448 --video-norm n --keep-hf --no-constraints
--sequence-header-every-gop --min-gop-size 6 --max-gop-size 6 -o
$NEW.m2v
Here is the full output to that:

**ERROR: [mpeg2enc] display_horizontal_size must be in range

The Canon file is 1920x1080 and 30P ==29.97.
When I change the frame rate code from 5 (=30) to 4 = 29.97 the message
about frame rate changes to:
++ WARN: [mpeg2enc] Specified display frame-rate 29.97 will
over-ride
++ WARN: [mpeg2enc] (different!) frame-rate 59.94 of the input
stream
That doesn't make sense, since the input stream should still be 29.97,
as it was before.
Anyway --- if you can offer some suggestions that will be appreciated.
Otherwise I'll have to buy Adobe Premium and edit in Windows ---
alas!!!.
