Editing large AVI files in VirtualDub

[steveh01]

I capture video using my ATI All-in-Wonder Radeon 7500 and VirtualDUB at 640x480 resolution (PicVideo's MJPEG codec). The resulting AVI files are 6 to 12 gig. I then encode these down to VCD MPEG1 using TMPGEnc. The results are wonderful. But there is a problem.

Some of the videos I do require editing (just simple cuts). I edit the AVI files in VirtualDub. But the resulting AVI files don't properly read in other programs. This is either a bug in VirtualDub or something I'm doing wrong.

I know I can work around this problem using compressed codecs to get the filesize down under 2 gig but I don't want waste the time or lose the quality if I can help it. I also have found that the latest TMPGEnc can do simple edits (cuts) so there is that option. But I'd like to have edited, high quality AVI files.

Is there a way to edit in VirtualDub (I'd prefer using direct stream copy mode) and save the resulting AVI files to large files that read in other software?

After you do your editing using Virtual Dub (using Direct Stream Copy as you said). Use Virtual Dubs Save as Segmented Avi Option you can have the segments to be as small as you like them to be.

Then Virtual Dub cab framserve the resulting Video to a Encoder.

Thanks for the quick response!

I'll try that. I haven't done frameserving before but I know that TMPGEnc supports it.

But I'm still wondering VirtualDub should do what I'm asking. I can capture huge OpenDML AVI files in Virtualdub (to an NTFS partition). Why can't it save them after an edit?

If your going to frameserve the video to TMPGEnc anyway, why bother re-saving the entire thing? Direct Stream Copy will discard filters, but will not discard cuts (ie: if you delete frames 1000-2000, then they will not be included in the frameserver), and TMPGEnc will open VDub's frameserver files (the .vdr) without problem.

"Save Processing Settings" and start the frameserver. Don't bother re-saving the entire file(s) as avi's, its a complete waste of time.

I see what you're saying. Frameserving without even creating a REAL avi file would be the fastest approach of all.

I still wonder if my original issue is a bug in VirtualDub (OpenDML indexes) but doesn't matter since I can bypass (or segment) my way past the problem entirely.

I also discovered today that the latest TMPGEnc (v2.57) has a new cut feature under the Source Range option that also will accomplish what I'm trying to achieve.

So in one day I've gotten three no-quality-loss solutions to my problem. I'm having a great day!

Thanks for all your help guys! I'll definitely come back here often.
