Encode with FFMPEG with multiple input files...

[RogerTango]

This is what I was trying, but it only encoded the first video (part1.avi) to the output video (finished.avi).

ffmpeg -i "part1.avi" -i "part3.avi" -i "part4.avi" -i "part5.avi"  -b 12000k -s 1280x720 -r 30 -vcodec libxvid -vtag divx -aspect 16:9 -acodec libmp3lame -ar 44100 -ab 128k -y "finished.avi"

Im missing something, which I cannot figure out. I tried adding some MAPping, but Im pretty sure I messed that up too...

Any advice would be welcome,
thanks-

Unfortunately FFmpeg cannot concatinate input clips. Multiple inputs are stacked in the output file. Mapping is used to select which streams from within a single input clip are used. You could use a small Avisynth script and feed that into FFmpeg.

AVISource("part1.avi", "part2.avi", "part3.avi", "part4.avi")

All clips must have the same specs.

Ahh, I forgot about the mapping specs... how true.

I cant do the AVISynth, the AVIs are of varying FPS.

Id be happy using Mencoder, but I dont think I have the syntax right... It also complained it could not demux the input file because it didnt know what it was...

mencoder mf://part1.avi,part3.avi,part4.avi,part5.avi -mf type=avi -oac mp3lame -lameopts cbr:mode=2:br=128 -af resample=44100 -srate 44100 -ofps 30 -ovc lavc -lavcopts vcodec=mpeg4:mbd=2:cbp:trell:vbitrate=3500 -noskip  -ffourcc XVID -o "final.avi"

I am more familiar with FFMPEG than Mencoder... but have used both with very good results.

Thank you for your time Chris,
Andrew
