Strange request, might not be feasible

Psyk · 22 Oct 2006 at 00:28

Ok I'm trying to fix an avi file with a corrupt header. I know a way to do this but I need another avi file with an identical resolution and at least as many frames. Now my request is either:

1) If someone could somehow create a blank video (ie each frame is just black) with a resolution of 524x212 and length of about 3 hours at 25fps. And then somehow get that file to me. Not sure if that will be possible. If every frame is just empty will it have a small filesize regardless of length?

or

2) Tell me how to make one myself, using freely available software (I don't have any proper video editing software).

Thanks for the help.

tried searching for tools to fix the header?

Have you tried to open the file in Virtual dub and getting it to fix the header automatically? Sometimes works for me.

Is virtualDub freeware?

I have found a tool that fixes the header but it needs a source file with a working header that has the same res and at least as many frames.

Ok got virtualdub, how do I fix the header? When I first open it, it seems to fix it but then when I try to save it, it tries to re-encode the whole thing which I don't want to do.

If you set the audio and video processing modes to Direct Stream Copy, that should just write out the existing data into a new file.

Hmm didn't seem to fix it properly. I'd like to try the other method to see if that helps. Is there a way I can use virtual dub to make a blank video to my specifications? Is there a codec I can use that will encode quickly considering every frame will just be black?
