Need to append one video to multiple videos

[woodface]

I have doubts that I will be able to find a program that does this, but I need to add a 15 second video to the beginning of a ton of other videos(both avi and wmv). I'd like to to be able to just do it in one step, rather than opening all the videos and joining each of them to the 15 second clip one by one. Is there any program that can do this, even in command-line--preferably without re-compressing the files? Thanks a ton

You won't have to recompress the original files, but the new video has to have the same properties as the video to which it's being joined. Since you have 2 different kinds of videos (AVI and WMV), already that means a minimum of 2 different intro videos for them. And if the larger files have differing resolutions, audio types, audio bitrates, AVI codecs (DivX and XviD, for example), then you'll need a different intro video for each. This isn't an easy task. You seem to be asking for a program that will automatically create or modify the intro to match the video to which it's being joined, and I don't think such a program exists. Maybe a playlist will do. Good luck.

I don't need to join different formats, but there are two types of files I will need to add the 15 sec clip to. In other words, I have a 15 sec avi that I need to append to the beginning of a ton of avi files, and a 15 sec wmv clip I need to append to the start of a ton of wmv files.

No mixing of formats, resolutions, or anything. Very simple in terms of the files involved, but I can't find a program that will append one file to many. Only joining multiple files into one big one.

Thanks for the link but that was one of the first things I tried. The resulting files were corrupt or had playback issues(maybe it doesn't like the MJPEG codec I'm using). It looks like I'll be doing this the hard way.

It's just kind of frustrating that there are hundreds of joining programs out there that could easily do this, but they just don't have this particular implementation of appending. Oh well. Thanks
