[squadjot]

Hi, found and older thread with follwing commandlines for FFMPEG

http://forum.videohelp.com/topic251008.html

ffmpeg -i %~n1.mpg -pass 1 -passlogfile %~n1 -b 3000 -minrate 0 -maxrate 8000 -bufsize 224 -vcodec mpeg2video -s 720x480 -r 29.97 -aspect 4:3 -hq -an foo.mpg
del foo.mpg
ffmpeg -i %~n1.mpg -pass 2 -passlogfile %~n1 -b 3000 -minrate 0 -maxrate 8000 -bufsize 224 -vcodec mpeg2video -s 720x480 -r 29.97 -aspect 4:3 -hq -an %~n1(720x480).mpg


It works for me, atleast i get a output file, but the script seems wrong to me.. Shouldnt 2nd pass have the output from1st pass as inputfile??

Also, I highly doubt you actually want a bufsize that small.
