Yep.... I prefer this way too!

Good point!

Off to download now!

I personally don't have any "mobile" device, nor do I have a "standalone" player. So I don't care about profiles, I use MPlayer or MPC+ffdshow. I want to archive captured video clips on my HDD and hence I need some "constant quality" mode. My clips are usually between 3 and 10 minutes, mostly live music. Some clips have a LOT of motion, some are more static. I want to have the "same" quality (more or less) in all my clips and I don't care if some clips are MUCH bigger than others. At the moment x264 + Psy-RD does a great job with it's "CRF" mode. So I use CRF=22 for most of my encodes, I rarely use 2-Pass. If you ever want me to consider DivX H.264 as an serious alternative to x264, you'll have to provide some mode like CRF...

LoRd_MuldeR: Ah Yes! I think there has been some misunderstanding. A CRF-like mode is absolutely something we are considering! I read "constant quality" as fixed qp, although it sounds like Stax still needs a qp mode for compression check.

Sorry to disappoint you:

I won't work much further on my GUI as long as there is only an "Alpha version 1".

Means: I may consider more efforts with a next encoder version... Patience. I have less life than ever before.

Nice going with this BTW! It had to come whilst I was at Greenbelt! How's speed with the same settings as x264 comparable?

Speed can still use a lot of work--in my test DivX goes significantly slower in its fastest mode than x264 goes with psy RD and psy trellis (--subme 6 --trellis 1 --bframes 3 etc). This presents a serious problem, for obvious reasons. DivX has a huge amount of room for improvement here, so one can hope that they'll cover some ground in the next release.

Greets,

Really enjoying testing out the new codec. Quality looks great. Encode times seem reasonable.

@LigH, thanks for the GUI. Very handy.

Cheers,
Rick

You may want to update a shortcut. Under Start Menu > Programs > DivX > DivX H.264 Codec CLI > Learn about DivX H2.64 Codec CLI, I think it should be "Learn about DivX H.264 Codec CLI"

Technically that's not completely wrong, Hertz is used as a measure of frequency, in this case frames per second.

Hz is generic unit of frequency. It doesn't matter what. Frames per second, samples per second, apples per second, bananas per second - Hz.
Something per second.
