Problems with abcAVI and VirtualDub

I'm on the last step of my newest video, and I've run into a road block. I've followed AD & ErMaC's guides, I'm editing in 24 fps and all, and I've exported my project in Huffyuv without audio, with plans to add it in VirtualDub.

Now, after exporting the finished project, I opened it in VirtualDub, and everything worked fine. It was still in 24 fps, so I proceeded to open up abcAVI and force 23.976 fps. After doing so, I open the file in VirtualDub again, but it gives me this error:

This AVI file doesn't have a movie data block (movi)!

Obviously, I don't know what this means, or what to do for that matter. Has anyone else come across this? Better yet, how do I overcome this? Just for reference, I'm using VirtualDub 1.4.11

That's really odd.

I'm guessing abcAVI must be changing something in the avi that vdub doesnt like... but that kinda sucks, I'll have to look into it.

What I recommend doing is making an avisynth script to import your 24fps avi into vdub as 23.976 like this:

AVIsource("c:/yourvid.avi")
AssumeFPS(23.976)

That should work fine.

I wouldn't recommend forcing the framerate in vdub as it doesn't always work. I'll have a look at abcAVI and see if I can get the same error.

Thanks, I'll try that tonight after I get back from the movies.

Just out of curiousity, how horrible would it be if I exported my project so it's 29.97 fps? I know it won't look quite as perfect, but will it look noticibly bad?

DO NOT DO IT O_O!

Premiere would interpolate your frames and it has horrible frame interpolation. You'd be better off just slapping the audio into Premiere in it's original form and exporting @ 23.98fps, but just don't do that. Just try assumeFPS, that should work.

Heh heh, on "Heroes", I forgot to make my intro 23.976fps, so VDub wouldn't read it.

I have a 29.97fps video stream and a 23.976fps video stream inside of one 29.97fps stream.
