High Quality XviD to DVD settings?

[Robert Simandl]

I have a very high quality XviD file, (960x528, 1913kbps, 23.976fps) and I'm having difficulty reencoding it to mpeg-2 for DVD authoring.

I'm using the current version of TMPGEnc Plus. First I tried 7000kbps average, 9000kbps peak, and got horrible stuttering on the final disc.

Did some searching here and found that can be caused by bit rates that are too high. Tried again at 6000kbps average, 8000kbps peak. Stuttering was greatly reduced, but not eliminated.

Other settings are:

Video only (ES).
720x480
23.976fps with 3:2 pulldown enabled.
DC Component Precision: 10.
Closed GOPs.

Before I reencode this thing dozens of times can someone with more experience suggest some settings they've known to work?

BTW, for grins I tried the trial version of the newer TMPGEnc XPress with as many of the same settings as I could (a few settings were unfamiliar). Didn't help the stuttering issue but got the encoding done in barely over a third of the time TMPGEnc Plus took, with no discernable loss in quality. Is TMPGEnc XPress really that much faster than TMPGEnc Plus all the time?

Thanks...

Frameserve AND resize the video first to your encoder..try virtualdub or AVISynth.....do you know its source? Is it 16:9 PAL or one of those NTSC HDTV jobbies?.

Download one of the HD files from Divx.com and do a comparison. That will tell you if it is your source or the encode.

Your field order could be wrong. Run your m2v file through restream (will only take a couple of minutes) and reverse the field order. then multiplex and author.

Monzie, It's one of those NTSC HDTV jobbies -- 23.976fps progressive.

Freebird, I thought if the source was progressive then field order should be irrelevant?

Soopafresh, you mean reencode one of those DivX Hd files and see if that stutters on the DVD player? Hmm, makes sense since it's probably safe to assume there's no jitter on the DivXes in the first place.

Thanks all, I'll put some of these to the test and see what I come up with...

Not really sure on that. I only know that on xvids and divx avis that I have had stuttering problems it usually was fixed by running restream and reversing the field order.

It might be worth a try since restream only takes a maximum of like 5 minutes. Then your authoring and burning time.

I seem to recall that someone else once had this problem and the answer was to encode to PAL 16:9...(maybe its because the source size is larger than 852 X 480 and the frameserver or encoder doesnt associate NTSC with that size?)
