Motion quality search precision (TMPGEnc)

[deejay_silva]

What is difference in quality between Highest Quality and high Quality converting from a divx movie file to an SVCD..??? I was also wondering what is difference in encoding time.

thx..

So far not one person has been able to see a visible difference between "high quality - slow" and "highest quality - very slow" settings in the motion precision setting in TMPGEnc. What everyone has noticed though, is that the duration almost doubled.

I'll dispute the statement that nobody has been able to see a difference. However, the difference seldom is worth the double duration.

On a high speed action sequence, Highest Quality will reduce blocking. There is another question somewhere in the forums where some kind person has provided a technical explanation of the differences between the two modes but I'm afraid I don't know exactly where.

From my own experience, I'd say that if it is something you can't replace with lots of fast motion, do it at Highest. If it's just another TV show that'll be repeated in a couple of months or that you will watch once every couple of years ( like most of my stuff ) just stick to High Quality. You'll get twice as many done that way.

Have Fun,

I have a pet eagle, and he said he can't see a difference either

Fair Enough......But what's his guide dog say?

( Sorry....couldn't resist it. )

The other way to reduce blockiness is to make a SIMPLE XVCD - namely, to crank up the bitrate - no need to play with sizes and other advanced stuff - just take the movie or show and cut it where you want and then fill the rest of the CD by upping the bitrate, just enuf to fill the disc. For example, I have a 50 min movie that i cranked the bitrate on to fill the 80 mins cd. I used High Quality with 35 35 block softening @ 1860 kbps ZERO blockiness and, since i used normal dimensions (PAL) it will likely not go flakey in most DVD players.

I find this a better solution than Highest Quality because upping the bit rate will not double the encoding time and as long as you dont mess with the dimensions or raise the bit rate to silly levels then compatibility will not LIKELY be compromised
