Noise reduction in TMPGEnc

[[GSV]Benny]

Hello,

When i am trying to covert my divx files to MPEG2 to be bruned to DVD is it recommend to turn ON "Noise reduction" and run the "motion search precision" setting in highest quality

Am i gonna notice a big differance

I want to get the best quality out of my files after they have been encoded and dont care about how long it takes

Cheers

The noise reduction will blur the image. How much depends on how high of a setting you use. A little noise reduction can sometimes be good. This will blur (blend) in some of the blocks from the DiVx video, and allows for a slight smoothing. Too much will blend in the sharp edges and details, making it look just awfull. I tend to use a setting of 5,2,5 with high quality checked.

Setting the precision to highest will give a better result, but if it's worth the time it takes is upto your eyes. Most swear they don't see a difference between high and highest.

No.

I think you've answered your own question. If you don't care about the time factor, DO IT. Go with "highest quality" and "2-pass VBR" etc. Otherwise go with "motion estimate search" and "CQ" or "CBR".

I personally would go with the highest settings if I was mastering one of my blockbuster epic motion pictures (filmed on DV minicam, ha!). Otherwise (for VHS archiving, say) I would go the shorter route.

I use TMPGEnc noise reduction (NOT "high quality" setting!!!) at default settings, but am lately wondering why I bother... considering that DVD players "smooth" the picture anyway...maybe tame the settings down to 5/1/16...!?

Good luck!

I use motion search estimate and can't tell the difference between that and highest. Be aware that noise reduction greatly increases the conversion time.

yeh,dont bother with it.
after you convert it to dvd,you wont really notice any degradation in quality from the original files,as tvs arent as high res as monitors.
i had "hero" divx,pretty blocky on the pc,but on dvd,looks much better.

Going to set "motion search precision" back to motion search estimate

Not tried "Noise Reduction" yet.
