How do I remove a bad frame from a video without VirtualDub or DivFix?

[teapot]

I've got a bad frame in a video I got, and I want to remove ONLY the bad frame. I can't do it in VirtualDub because it's between keyframes, and it happens during a moment of dialogue, so I don't want to cut that whole thing out. DivFix doesn't recognize it and trying to re-encode it in VDub causes it to crash. (It also crashes DivX Repair.) Here's the crash report:

I can't understand why, if it's able to crash programs and cause an error in encoding to DVD, DivFix doesn't even recognize it as a bad frame. Any idea what I can possibly do?

[jagabo]

I don't think DivFix decodes the frames. It just steps through the chunks of the AVI file looking for key frames and makes a new keyframe index.

Another thing to keep in mind: if you find a program that allows you to substitute something else for the bad frame the remainder of the GOP will still be messed up. Does VirtualDub crash when it gets to the bad frame? Try using a different decoder. You may find one that doesn't crash, just leaves you with a messed up picture.

[sambat]

How about select the first part (before the bad frame) and use Smart Rendering (selecting the same compressor as the source) and save it.
Delete that first selection and step forward past the bad frame, select the rest and save as before.
Load the new files and save Direct Stream Copy.

[teapot]

^ Tried that. First part saved ok, but it still crashes when trying to save the second part. :\

[jagabo]

That's because it has to (attempt to) decode the bad frame in order to decode the rest of the frames. A different decoder may not crash letting you get past the bad frame. The rest of the GOP probably won't render correctly but it's better than cutting out the rest of the GOP.

[teapot]

What other program can decode/remove bad frames so that I can create a DVD of this file without all but the first 25 minutes of video blacked out?

I'm also going to try to redownload the video, cause I asked about it at the place I got it from, and so far no one's had any problems.

[sambat]

Here's and old thread touching on this.

https://forum.videohelp.com/topic153907.html

[jagabo]

What other program can decode/remove bad frames

You can continue using VirtualDub. Just use a different decoder for the video. It appears you're using Divx to decode. Uninstall Divx and install Xvid. Xvid may not crash at the bad frame. Or try ffdshow. Or a different version of Divx.

If you find a decoder that doesn't crash you may be able to feed the video directly to your MPEG encoder, skipping VirtualDub entirely.
