resultaat: mov speelt niet in VLC/ cinelerra / kino na hernoemen in DV: speelt in VLC gepixelde kwaliteit A+V niet in cinelerra / kino

omzetten van een MOV in MPG[edit]

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[edit]

-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

21/1/2006 CINELERRA export: fileformat Quicktime for linux audio Mp3/ bitrate 256000 video= DV -> speelt in VLC -> probleem: kopieert niet naar schijf

samengevoegde mpeg, bestaande uit MPEG-2 audio en MPEG-1 video[edit]

 cinelerra / render / MPEG Video, yuv 4:2:0, Generic MPEG2, Derivate MPEG1 (filename  ot-portretTESTvideo)
 cinelerra / render / MPEG Audio, layer II, 320 kbs (filename  ot-portretTESTaudio.mp2) 

daarna in ffmpeg samengevoegd

Transcode MOV to Theora[edit]

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[edit]

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

 "anxenc example.cmml -o example.anx"

=> example.anx
