I have several raw (uncompressed) AVI files, each is several GB (max 5 GB)
I run the command line below from windows cmd shell,
c:\>ffmpeg -y -i input.avi -s 800x600 -aspect 4:3 -vcodec mpeg4
-vtag xvid -r 25 -b 1000k -g 250 -me_method epzs -qmin 2
-qmax 15 -acodec libmp3lame -ac 2 -ar 44100 -ab 80k out.avi
ffmpeg encodes maximum 35 seconds, even if the movie is longer, without any error message.
i tried to add time limits to longer than that, in various ways, but the longest encoding output was 35 seconds.
here's the commandline and output
