omzetten van een MOV in MPG

Probleem: ffmpeg zet wel een in Kino gecapturde mov om in een ander formaat (mpg) maar geen Mov die vanuit cinelerra gerenderd is

ffmpeg fuse van audio en video

-video MPEG-4 -audio MP3 naar mpg

 ffmpeg -i (videofile) -i (audiofile) (outputfile.mpg)

resultaat: speelt in VLC

16/1/2005 ' probleem: CINELERRA crasht op videorender DV settings niet opgelost

Transcode MOV to Theora

1.You have a somehow acquired QuickTime MOV file: "example.mov". 2.Dump YUV and WAV from MOV:

 "mplayer -ao pcm -vo yuv4mpeg example.mov"

=> audiodump.wav, stream.yuv

3.Transcode to theora:

 "encoder_example -o example.ogg audiodump.wav stream.yuv"

=> example.ogg

Create Annodex files

1.Write CMML file: "example.cmml" 2.Encode Annodex:

 "anxenc example.cmml -o example.anx"

=> example.anx
