I've found that the MPEG-4 profile produces good results and I would like to use it to encode multiple small clips.
I do not want to add every clip to the timeline and render it.
How can I convert the rendering parameters
f=mp4 acodec=libmp3lame ab=128k ar=44100 vcodec=mpeg4 minrate=0 b=12000k aspect=%dar mbd=2 trellis=1 mv4=1
to arguments to ffmpeg or another command line conversion tool?

Thank you!

-f mp4 -acodec libmp3lame -ab 128k -ar 44100 -vcodec mpeg4 -minrate 0 -b 12000k -mbd 2 -trellis 1 -flags +mv4

You helped me a lot, thank you!
