103GB no-content AVI File

[koberulz]

Used my BlackMagic Intensity Shuttle to capture an MJPEG AVI that should be in the ballpark of two hours. Windows lists it as zero seconds long, MediaInfo as 1 minute 47 seconds long. There's a thumbnail preview in Windows Explorer.

I can only assume I closed Media Express before it'd finished closing up the file or whatever it does. Can I recover it? It's still 103GB (Windows)/104GB (MediaInfo), so the content should all still be there.

EDIT: Previously failed to open it in Premiere Pro, VLC, and VirtualDub, at which point I gave up and posted, after which it occurred to me to try MPC-HC and it works. Can't skip ahead though, so I'm not sure how long it works for.

It's odd VirtualDub won't open it if MPC-HC can play it. You don't have any VirtualDub decoding plugins that might be opening instead of VirtualDub opening it directly (choose AVIFile Input Driver from the file types list at the bottom of the File/Open window to ensure it's not being opened by a plugin).

Other than that, all I can suggest is trying to remux it using a few different programs. VirtualDubMod, AVI-Mux GUI and MKVToolNixGUI. You could even try remuxing with ffmpeg.

What happens if you try and open it in an AviSynth script?

AviSource("Capture.avi")

If that works you could resave it in a lossless codec (Lagarith, UT Video Codec, etc.).

In VirtualDub? Same thing that happens if I just try to load the video.

If you please:
- Restart vdub.
- Try to open the file.
- View menu, Log.
- Right-click, Copy to clipboard.
- Paste in your next reply.

I'm running it through ffmpeg ("ffmpeg -i [file].avi -vcodec copy -acodec copy [file]2.avi") and it seems to be processing okay. It'll be a while before it finishes though.

In case FFmpeg doesn't work for you, try DivFix++. It's pretty good at rebuilding AVI indexes.

[koberulz]

The ffmpeg result works perfectly.
