Problems appending avis


I have a season of videos that I would like to append to fit onto a DVD. I tried to used a program called avidemux to append the vids but it screws up the aud/vid sych. All the avis are the same BR and fps.

This is what I did:

Open an avi with avidemux, append 2 more avis-->convert to mpeg 2 format using ffmpeg lava codec first then save audio as an AC3 file (this is the only way to keep the audio/vid sych). I made sure to build a VBR map. Then I used mplex to combine the files and produce a final mpeg with audio (avidemux screws up multiplexing xvids).

For a single file avi-->DVD file this works awesome. The problem is when I append an additional avi to the first. The audio/vid sych is perfect until when the second avi begins playing. Then it goes to hell.

Someone mentioned mencoder to appends avis but I can't figure it out. The code on the mplayer site is this:

cat 1.avi 2.avi > 3.avi
mencoder -noidx -ovc copy -oac copy -o output.avi 3.avi

For the life of me I can't figure out how to use this code. Can anyone give me any examples using real file names?

If you have anymore suggestions I would love the help. I really don't want to use 1DVD per avi if I can help it.

I just tried it with one of my avi files... maybe this helps...

cat "Ray part1.avi" "Ray part2.avi" > RAY.cat.avi; mencoder -noidx -ovc copy -oac copy -o RAY.avi RAY.cat.avi

Basically, its just ...

cat movie1.avi movie2.avi movie3.avi > allmovies_concatenated.avi
mencoder -noidx -ovc copy -oac copy -o allmovies_final.avi allmovies_concatenated.avi

...and you end up with a file allmovies_final.avi that should be all synched up and ready to go.


If you're looking to put your avi's onto a dvd to watch in your DVD player. You should take a look at this:

Good Luck
