Hi
I'm editing an MPEG2 (from a DVD) in TMPGENC Mastering Works 5 and about every other cut I make, I've been hearing a loud pop/clicking noise. They're at the end of all my cuts.
I can get around this using Sony Vegas and the crossfade transition...only thing is I lose quality in Vegas and the de-interlace method in TMPEG is second to none. Never mind the fact the hard cuts in TMPGENC look very professional.
Any ideas?

There is a description on the problem and remedy here.
However, it is not for TMPG Master Works. I don't use it, so I cannot advise.

Vegas pro smart renders mpeg2, if you set it up properly so there is no quality loss with simple cuts (only the few frames around a GOP cutsite if you are not cutting on keyframes). Only filtered sections, overlays, and transitions are re-encoded.
But if you are deinterlacing for whatever reason, the entire thing will be re-encoded. Avisynth offers some better deinterlacers than TMPGEnc -

Thanks trasporterfan (just tried this in Vegas, works nice), but I don't have a waveform in TMPG where I can detect the zero crossing points.
Well, I'm encoding the MPEG's to a HQ Divx file and eventually want to upload them to Youtube. I assume I will lose some quality. I've worked with Avisynth (restoration scripts), but I still like the results in TMPG better. -

I want to edit said MPEG and re-encode to a HQ DIVX file. -
Strange that it shows as both progressive and top field first interlace. Is this camcorder video?

No, it's an NBA game from a recorded VHS tape. I bought the DVD's from a friend - and yeah that is weird. Most of them are Top Field / Interlaced.
I'm really not sure why I lose a considerable amount of quality in Vegas though. My project and media properties are set to that of the MPEG's. Absolutely identical. If I could just find out what is causing those loud pops/crackles in TMPG...
