I've been using yuvkineco/mpeg2enc for pulldown. It stays perfectly in sync until it
reaches around 100 minutes into the video. Then it gets WAY out of sync. It isn't
slowly getting out of sync at 100, it just suddenly gets out of sync.
Any ideas?
If I use shorter videos that are less than 100 minutes I don't ever seem to see the
problem. Certainly that could be coincidence...
Here's the scripts I use to encode. BTW, if I do not use pulldown and pass yuvkineco
-F 4 rather than F1 and don't pass -p to mpeg2enc it does play in sync, and it doesn't
matter if I use mplex, tcmplex, or ifoedit to merge the audio/video - they all get out
of sync at the exact same point.
Convert nuv to m2v w/pulldown script:
echo Converting NUV to M2V with pulldown
nice exportvideo -D 0 -Y 2 ${aName}.nuv 2>/dev/null | \
nice yuvscaler -I ACTIVE_$Border -O INTERLACED_TOP_FIRST -v 0 | \
nice yuvkineco -F 1 | \
nice mpeg2enc -f 8 -b ${aRate} -V 230 -n n -s -a 2 -g 6 -G 18 -I 0 -Q 0.00 -r 24 -4
3 -2 1 -N -v 0 -p -F 1 -o ${aName}.m2v
Audio:
mkfifo ${aName}_441.raw
mkfifo ${aName}.wav
nuvplay -e $aName.nuv > ${aName}_441.raw | \
sox -t raw -r 44100 -s -w -c 2 ${aName}_441.raw -r 48000 -t wav ${aName}.wav | \
ffmpeg -i ${aName}.wav -ab 224 -ac 2 -ar 48000 -f ac3 ${aName}.ac3
rm -f ${aName}_441.raw
rm -f ${aName}.wav
Any ideas on what is going on here? It is as if yuvkineco suddenly starts dropping
too many frames or something. It is really weird!
Thanks!
