TMPGEnc Glitches on MPEG2 encode

[ntrprs]

Recently I have been experienceing random glitches in the encode of AVI->MPEG2 files using TMPGEnc. These glitches appear as digital noise (sometimes a group of 20 pixels or so and other times half the screen!) The AVIs do not have the problem.

I am capturing PAL VHS via an ADVC-100 and loading these into Virtual Dub , (where I add a few cleanup filters) and then frameserve to TMPGEnc where I convert to MPEG2 and WAV (via separate streams). I then convert the audio to AC3 (Softencode) and then MUX with TMPGEnc tools before I edit out the commercials in VideoRedo.

The glitches I have been finding are in the original MPEG2 encode (ie before I do the audio conversion and edit the file in Video redo).

I have checked the PC for viruses (there were none) and even run AdAware and Spybot to remove any potential anomalies that may cause this behaour in another programme. I have unstalled TMPGEnc (completely) and reinstalled it, and so far the system is working. I will have to check my next few encodes (by viewing the entire files) to confirm that the problem has disappeared.

Has anyone else come accross similar glitches in TMPGEnc and how did they diagnose and solve it?

I would suggest you not do editing after encoding. But edit your file before you encode. It just makes more sense.

Also, have you defragged your hard drive? That is the best thing to smooth out any rough or bumpy areas of the process.

Defrag after emptying out useless files. And it is a faster proicess if you have no video files on the system when you do it.
