Compress AviSynth / VirtualDub Output

Sometimes I output from VirtualDub in an uncompressed format.

Works with pdfpc:

F="file.avi"; avconv -i $F -acodec pcm_s16le -ac 2 -b 100000k -ab 100000 ${F/.avi/}-c.avi

Better audio compression:

F="file.avi"; avconv -i $F -acodec libmp3lame -ac 2 -b 100000k -ab 100000 ${F/.avi/}-c.avi

If Unknown encoder ‘libmp3lame’:

sudo apt-get install libavcodec-extra-53
