DivX to mpeg2 motion quality issues.

[canuck94]

Greetings all.

This isn't a noob question, but it seemed to be the best place to post this question based on it's content.

I'm converting avi files to DVD compatable mpeg2 files. I'm using TMPGenc 3.0 Xpress to do the conversions. Most times this programs is a great one click conversion tool but I found a passage that had a lot of motion (picture your typical earthquake scene with a very shaky camera) and the converted image was terrible. It was very pixelated, blocky, and had many horiszontal lines running throug it. I bumped up TMPGEnc's setting for maximum quality (DC component precision: 10bit, Motion search precision: highest, 2 pass vbr with the bitrates of min, avg, max at 300, 2050, 8000 respectively) and this helped but I'm still not happy. I could pump up the average bit reate which would improve the image, but if I do that it will take more DVD as I'll be able to fit fewer videos on each disk.

Can someone suggest a different tool that may do a better job of converting the high motion scenes or suggest some alternative method of doing the conversion?

many thanks,
C4

The simple answer is you aint got any bitrate.

Lets take 300 minimum (thats 1/3rd of the allocated to 1/4 res VCD!).

Lets take average 2050 (thats around the same a SVCD...about 60% DVD) BUT this setting is the AVERAGE for your movie!

Lets take max 8000 (thats nearly 4X higher than your average) and not sustainable throughout your entire movie.

Monzies verdict: Go back to school.

You would be far better of using CBR.

Whats the length of the movie?

PS. Is it an earthquake or a home porno?

I am converting to DVD at 3400 average and feel bad about it (at least I do 1+3 CCE passes on them).

If your video is full frame (720x480/576) then 2MBps is by far inadequate.
