Can Editing my movie reduce it's quality?

[warlock110]

the situation is this, after struggling for the past 2 days i've found a good way of capturing that would leave me with good result, and what i've done is capture in AVI with the huffyuv at max setting, 1 hour of VHS cost me 40GB, but that's ok space is not a problem. I then convert that to DVD using TMPGEnc with the "noise reduction" filter, using VBR and highest setting, result was pretty good, although it was rather slow.

But the main problem is that i want to add animation text to the clips as well as narriation to it. The way that i've know to do this is to use Ulead VideoStudio 7 SE DVD software, but at the end i have to render the clip again. will this some how reduce my quality? i've sorry if this is such a stupid question, but if i were to test this myself it would take hours and i really need to get this project done. I'm gonna relies on the experts in here

to sum it up, i'm going with this route
AVI to DVD using TMPGEnc
Edit with Ulead
Render out to file
Author with TMPGEnc

will this reduce quality comparing to the product that i've done before? what i've done before is this

AVI to DVD using TMPGEnc
Author with TMPGEnc

Yes. AFAIK, Ulead reencodes the whole mpeg again when it outputs, even if the source material is compliant.
Even if TMPGEnc produces better mpegs than UVS (IMHO), I'd drop that step, and use the AVI as video source in UVS, edit, and render. That way, you'll at least not encode twice.

i'm willing to rencode twice, but the problem is I need TMPGEnc for the "noise reduction" filter, this filter really help improve the quality on my capture VHS, from various experiement with many encoder, it seems that with this feature turn on, the picture was very clear, or else the movie will get real messy, that's why i wanted TMPGEnc to go through the source 1st before crappy ulead step in does ulead have this type of filter? and is there anyway to intergrade TMPGenc encoding system in ulead?

does ulead have this type of filter? and is there anyway to intergrade TMPGenc encoding system in ulead?

"Don't know, but seriously doubt it!" and "No".
The filters I've seen in UVS seems more aimed at "Cool Effects"...
But maybe you should try filtering with VirtualDub instead, AVI to AVI...
But then again - why not try your new route? None but yourself can tell if you're satisfied with the outcome!

In my opinion, TMPGenc's noise reduction filter produces great results, but it's so slow as to be almost completely unusable - and a have a 3.2 ghz machine.
I would suggest capturing with Virtualdub using it's built-in noise reduction algorithm, or post-processing with Virtualdub using SNR - static noise-reduction filter >

Or, filter with VirtualDUB while frameserving into TMPGenc, ie. AVI to MPG. Good if you can't afford to store the intermediate AVI...

I don't quite follow.

I have a 1.8Ghz machine, and I just got done with a project that used 4-5 TMPGENC filters, including this one, and 6 hours of footage only took 40 hours to encode. Did it in two 20-hour shifts.

Ulead Doesn't support frameserving ???

If yes, load your avi (40gb) in Ulead, apply your effects and then frameserve your video to Tmpg and apply your Noise reduction.

That avoid reencoding all all is done in one step.
