Unofficial VirtualDub Support Forums > Newbie Questions > Ran Out Of Memory During Video Capture Mode


Posted by: cornflakes Apr 10 2014, 08:42 AM
I've been using Vdub for years now and the video capture mode has been very useful.
However, sometimes I'm forgetful of how much memory I had left available on my hdd and kept
the recording too long. As a result, I never STOPPED the video capture (by pressing hotkey ESC), but
it just stopped on its own due to lack of memory space.

This happens once every dozen times or so (i'm forgetful or there was less memory than I thought, etc).
When I go to check my recorded file, I see that the size of the file indicates a full recording as been made (ie,
20 gb or 40 gb file). But when I go to play it, it won't start or open...usually just a black screen. So then I try to
open it in Vdub and it tells me it is reconstructing missing index blocks. This usually takes a few minutes.

Once it is done, I can play the video and its viewable, but only a few minutes are viewable. For example, I can
only see 4 minutes of a 30 minute video capture.

Due to the size being large, I know that the information must all still be there and have been recorded, but I'm not
able to see it all.

Does anyone know how to make the file fully viewable? Or is my recorded footage irrecoverable and lost??

Basically, if I had just pressed ESC during capture before I ran out of memory, the file would have been 100% fine.
But since the capture went too long and beyond the available memory on my hdd, it just stops on its own but the files
always seem to end up unwatchable or "damaged"??

Please help! thanks

If you would please, after you open the file in VirtualDub, hit the File menu, File Information. Now hit Copy; start a reply message here and right-click, Paste.

thanks for the reply, actually it worked thankfully somehow.

The file was originally on my netbook and whenever it tried to rebuild missing index blocks in vdub, it only ended up with about 40 seconds of viewable video of the 40 minute clip.

I decided to transfer the 42 gb file to my main comptuer (desktop) where it's much faster cpu. I also used vdub 1.10 stable version and when I opened the file there, it was doing the same rebuidling missing index blocks procedure but this time upon completion, i was able to view all 40 minutes of the video capture file! Thank god. So then I saved the file as an xvid compressed file and everything is fine.

I'm not sure if it was because a faster cpu computer can rebuild missing index blocks better or if it was because I used the new vdub 1.10 version (i was previously using the 1.7 to 1.9 versions).
