QPEL questions

[chilledinsanity]

I'm wondering how safe it is to use QPEL. I still have the latest Xvid build before it went beta and I'm deciding I like the results better with it. I can't recall whether it was safe to use or not though without having occasional glitches.

As for the latest beta I downloaded from Koepi's site, it appears that QPEL isn't even an option. Is the new build that much better so that QPEL isn't needed or is not stable enough to be in the beta or what? I could just be missing the option somewhere, where I have to enter a numeric value as opposed to just a checkbox before.

Any help would be apprectiated, I'm no expert when it comes to tweaking the Xvid settings.

:p starting from xvid 1 beta 1 the vfw gui has changed a bit.
it has a lot of 'hidden' buttons:
try clicking on some of the square boxes with the three dots

if you just meant that Q-Pel was grayed out then that's probably because you've selected a profile that doesn't support it.
try 'Unrestricted' profile

better start reading the major beta release threads started by koepi (aloha, ciao, selam), there is some cathcing up to do ;)

wow, I'm an idiot, you'd think I would have noticed the ...

Thanks for the quick reply. Yeah, I should probably read those posts, but the 260 reply thing sort of discouraged me

:) you 're right, the threads are huge, i 've only fully read selam myself :rolleyes:

some quick cathing up then:
most of the settings in xvid 1 beta are similar to the dev api 3 builds (except now they actually work):
lumi masking is now known as adaptive quantization
b-frames are called B-VOPs
b-frames ratio & offset use a different scale, ie where you used 100 in dev api 3 you now use 1.00

new stuff:
reduced resolution --> useful for video streaming
cartoon mode
turbo (read syskin's sig)
trellis quantization
aspect ratio: see these two threads :

zones: grayscale, b-frame sensitivity (threshold) & chroma optimizer reside there now, it's also the new way to compress credits more

be sure to take a look at this guide to catch up on the new settings as well:

In the last koepi alpha from june, Q-Pel was fixed and works fine. I havent had any problems with it. The alpha from may had that q-pel smearing that weve all heard so much about haha.
