    Join 2 asf files

    Hello,

    I got 2 videos in ASF format. One has 122,6Mb and the other 29,1Mb. I'm trying to join them in a single file. Yet, when I try to do this using ffmpeg or mencoder the resultant size is FAR greater than the original file.
    I tried like this:
    mencoder -oac copy -ovc copy -idx -o output.avi video1.avi video2.avi video3.avi
    like this:
    mencoder -oac copy -ovc copy -o output.avi video1.avi video2.avi video3.avi
    like this:
    ffmpeg -i ./video1.asf -i ./video2.asf -vcodec copy -acodec copy ./video.asf
    I tried with cat as in:
    http://ffmpeg.org/faq.html#SEC27
    tried to join both with cat vid1.asf vid2.asf > vid.asf and then convert with ffmpeg to .mpg.
    No deal. I can create the joined video but the least I get is 300Mb.

    Somebody knows how I can do this keeping the original size ? i.e. the resultant file should have aprox. 151,7Mb.

    Thnx
    -Nelson

    Perhaps you have made a typo, the technique is to convert both files to mpg first, then cat them together and then finally to convert the concatenated file to the format and container of your choice.
    You think that's air you're breathing now?
