Sorry, you’ve written “With a more recent version”.

Do you mean it’s better to install ffmpeg from other source to get a newer version, so that I can use your command?

[Peter Zebke]

I’ve installed ffmpeg from the default debian squeeze repository.
If I try your command it fails:

>ffmpeg -i test.mp4 -s 960×720 -vcodec libx264 -preset slow -vprofile baseline -crf 20 -pix_fmt yuv420p -acodec libaacplus -ar 44.1k -ab 32k -ac 1 -f mp4 -y target.mp4

[NULL @ 0x98aca60] [Eval @ 0xbf9de63c] Undefined constant or missing ‘(‘ in ‘baseline’
[NULL @ 0x98aca60] Unable to parse option value “baseline”
Invalid value ‘baseline’ for option ‘vprofile’

The complete output from my first command:

>ffmpeg -i test.mp4 -s 960×720 -vb 2000k -vcodec libx264 -vpre normal -y target.mp4
