[mythtv-users] OT: ffmpeg - help with poor output quality

[Michelle Dupuis]

I have a job setup to convert myth recordings to a format I can use on my blackberry.  I built this based on snippets I found around, and it seems to work other than the output quality is very poor (but nice and small).  The output is grainy/blocky; can anyone suggest which parameters to tweak to improve quality?  Thanks

ffmpeg -i "/mythstorage/recordings/1201_20120626233400.mpg" -acodec aac -strict experimental -ab 128k -ac 2 -vol 2560 -s 800x600 -vcodec mpeg4 -flags +aic+mv4 -trellis 2 -cmp 2 -subcmp 2 -bufsize 20M -g 300 -metadata title="The Colbert Report-Richard Ford" "/tmp/The_Colbert_Report-Richard_Ford.mp4"
