BTW, what codec was used for that AVI-video? DIVX? Ever tried AVIDEMUX(2) for cutting it? > I just tried that and DVBCut > didn't like it too much.

For what it's worth, here's the line I used to shrink the file > (it was 640x480 and this command cut it down to 320x240): > > ffmpeg -i input_file_640x480.avi -ar 22050 -b 500 -s 320x240 > output_file_320x240.mpg OK, with a bitrate of only 500 bits/sec it's no wonder that you ended up with just 6 MB. Could you really see a proper video...? :) You have to specifiy "-b 500k" if you want KILObits/sec!!! But with MPEG2 this also would give a rather bad quality... are you really sure that it's a MPEG2 video in an AVI container? I never saw that... and with your command line you didn't changed the codec.... > Would welcome any other ideas!!! For cutting with DVBcut I would convert the video to a rather large bitrate MPEG2 stream to preserve the quality as much as possible (without changing the resolution!)... maybe with "-target DVD -s 640x480"... and additionally a "-acodec copy", if the audio is already coded in MP2/AC3 48kHz. But if not, you have to specify "-acodec mp2 -ab196k -ar 48000", otherwise DVBcut probabely does not recognize the Audio channel. After cutting you can shrink it down again to a AVI/DIVX with [EMAIL PROTECTED] and [EMAIL PROTECTED]/22kHz or whatever... I usually use: ffmpeg -i INFILE -f avi -vcodec mpeg4 -b 800k -g 250 -bf 2 -s 640x480 -aspect 4:3 -acodec mp3 -ab 128k -ar 44100 OUTFILE ciao, Ralph > > On 7/30/07, Michael Riepe <[EMAIL PROTECTED]> wrote: > > Hi! > > > > Footer wrote: > > > Well ... both? > > > > I doubt that will ever happen.
