Editing w/ Virtualdub problem

[RodNichols5]

I hope this is the right forum. I have been capturing and editing video to convert to SVCD for some time now, no problems. This is usually TV shows and I edit out the commercials. I capture at 352x480. Now that I have a DVD burner, I have tried some DVD captures. But, if I capture at 720x480 to an AVI file, I have trouble playing back the file in Virtualdub. It will play for about one second and then it seems that the audio is interrupted every second or so. I need to play the file as I am taking out commercials and I want to make sure the audio and video are synched up properly. Could it be that I need a faster processor ? My full system specs are in my profile but here are the important ones:

Win ME
ASUS A7V333 Via KT333
1.4 Ghz AMD Athlon XP 1600+
256Mb DDR SDRAM PC2100
120 Gig WD 7200rpm ATA-100 + 160 Gig WD 7200rpm AT
ATI AIW 7500 Radeon

Any help or words of wisdom would be appreciated !!!

Thanks !!

Playing back in VirtualDub? I don't think there's a play option - are you sure you're using the right software?

[RodNichols5]

Well I guess I mean using Virtualdub's frameserver to send the file to Tmpgenc. There is a play option that you click on and the file plays. I check to make sure that I did get the commercials out and also to see if the audio is synched correctly. Sometimes in my catures the audio gets out-of-synch with the video and I don't know how to check it except to play the file in Virtualdub before I frameserve it to Tmpgenc.

I'd check the original avi file first - out of sync can easily happen with dropped frames during capture. There should be a box to tick when setting up capture to allow for dropped frames.

If the avi is fine then I'd cut each segment of the avi into a separate file and let TMPGEnc encode them separately.

There is nothing wrong. My system specs are almost identical to yours and I get the exact same effect. It's just due to the large datarate, try WinDVD for playback, I find it gives the most accurate results.

I agree that it is probably a high datarate issue. That happens to me when I capture uncompressed but NOT when I capture Huffy

This same thing happens to me when I edit with virtualdub after capping via my ADVC-100 into DV. Luckily the ADVC-100 has the audio synch lock feature. I just edit out the commercials by sight and it hasn't affected the sync on any of my caps though.

Thank you Nelson37, NickSaunders, and jimmalenko, I feel better now. I suspected that it was the high datarate. Nelson37 I will try WinDVD. I actually thought about changing my screen resolution but I don't think that will have any effect. I might try to upgrade the processor, I have been thinking about doing that for awhile.

Thanks again !!
