How can I convert to Mpeg2 with Perfect quality?

[grimreaper]

I've been practicing for a long time with Tmpgenc in converting my .avi to mpeg2(DVD). No matter how much I practice I don't really get a perfect quality picture. The quality of the .avi is perfect but when it get to T.V. it looks like crap. Is there anyway I can make the picture more clearer with the color more brighter. And my last question, Half way through the movie the sound gets out of sync. I use virtualdub for the sound. Any suggestions would be great cause I know I didn't get a DVD burner for the quality of picture I'm getting. Thanx...

dude,

not enough info.
* your source? ie, capture or dvd
* your settings, vcd or svcd?
* viewing on a TV or PC?
* resolution
* what R U'r quality issues, ie, blocks, etc.

sounds like you're capturing, and if so, you wont get DVD quality or
did you say, "perfect quality" ??

No such thing as "perfect quality"
...but good or great quality

I'm using .avi movie I downloaded. I'm using the Tmpgenc template of DVD NTSC to encode it to MPEG-2. I've tried it once but the picture quality wasn't the greatest in the world. Which setting should I check mark to increase the quality. What about the GOP Structure? If I mess with that can I change the quality of the picture. The .avi movie that I'm encoding is perfect but I want to be able to watch it much clearer when I burn it to DVD to watch on a NTSC T.V. If anyone has anymore suggestions it would be greatly appreciated.

I'm having the same issue and just posted to the newbie forum since I'm new. My problem - any motion in the resulting output is severely pixelated and appears as streaks.

My information: original image captured on Sony Mini-DV camera(TRV17), transfered via firewire through MediaStudio Pro 6.5 capture to .avi file. Edited in MSP and output to .avi. output looks tremendous. Tried to create SVCD using Nero (default settings) and saw that I had to create .mpg first.

Downloaded TMPGEnc and encoded .mpg2 using default settings (NTSC). .mpg output has the problems so it's definitely in the mpg conversion. Don't know if I need to play with sharpening, edge enhancement, or anything else.

Any other information would be appreciated

Try setting the motion search percision to "high quality (slow)". Don't bother with the "best (slowest)" setting. Not much difference and takes a lot longer.

I am going to try this again. I have lost my post twice before sending it. Check the resolution of the Download file sometimes downloaded files have reduced resolution. They will play fine in a small box on screen but look bad full screen on PC or TV.

You may want to try to deinterlace. I know with movies I capture from my DV camera I always have to deinterlace. If you have the problem of jagged edges around high motion areas that can be caused by interlace problems. Using deinterlace will slow down your encoding alot. I have an ATI all-in-wonder and it captures in real time to deinterlaced mpeg 1 and 2. I have gotten better results with tmpge but that takes hours and hours. I get VHS quality in real time with ATI and I would rather watch the movie than watch the PC encode the movie. I use the highest bit rates my DVD player can handle. This limits me to about 30 min. per CD, but who wants to watch a home movie any longer than that?

What do you do with input source defination ?
The DV is 720 x 480 and TMPGenc think 704 x 480.

Since DV is interlaced and TV is also interlace. In theory, if we can leave source and output interlace and make a SVCD that play on TV.

How is it the de-interlace version look better ?
I read somewhere de-interlace reduce resolution, is it through ?

grim,

Sorry I didn't catch this question ta ask ya, I had to re-read your
post. Finally dawned on me. You said movies you D/L!!!
No wonder why you can't get that "perfect dvd quality" It's a DIVx
AVI!!!
Yes, it will look fine when you play it!! ...why????
cause whatever artifcats you can't see, is proably so minute during
play that you are lead to believe it's a perfect play every time!
BUT, when you bring this DIVx into your encoder. Guess what? Your
encoder (in short) sees these artifacts!!
So, when tmpg/cce encodes this perfect DIVx, it's showing or including
the flows or artifacts of that DIVx encode. No, i'm not bad-mouthing
DIVx. Really. I'm just telling you why you're not getting that perfect
mpeg2 quality, using the "DVD ntsc" template that you stated earlier in
your post (the one I had to re-read, and understood after all) that you
used for encoding to MPEG-2!!
Really! ! ...that's why!!

I'm assumning, that by "DVD ntsc" template you used, you didn't make
any changes to it, ie, resolution (720x480), etc.

What was the resolution of the DIVx clip???
640x272? ? ? (figures) or, maybe even less.

Welp, that's basically it, in so many words, what you problem is, with
the MPEG-2 quality delima. There's you answer. You post just wasn't
clear enough.

Please tell me I'm wrong! ...if I truely am!!

Had you encoded a DVD movie, using the "DVD ntsc" template, you'd
get that "perfect MPEG-2 quality" he, he.... ...wel close anyways.

AVI downloaded from the Web will not give good quality after encoding.
vhelp is right, those AVI are really Divx (which means they are already compressed to VCD quality level).
