[x264-devel] x264 quality improvements?

[Marc Schulz]

Well if that's the attitude you want to take you'll have to re-encode every
time there is a commit to git.  Additionally you never mentioned it being
for mobile platform. On a mobile platform I couldn't see any improvement
that doesn't allow for the same quality at approximately 30% less size being
of any great importance that justifies a re-encode considering that even the
quicktime moves I got when purchasing various blu-ray titles show artifacts
on my computer monitor but you can't even hope to see on my iphone. 

 

Either way you're not likely going to see any improvements that will make it
necessary to waste your life away re-encoding all your mobile movies several
times per year. I would recommend going outside and getting some fresh air.

Seems a bit silly to ask considering they are always improving something.

Why don't you just encode lossless instead of reencodong everytime there is
an improvement in quality. That way no more time wasted needing to reencode.

Besides the weight-p patch, are there any other features that'll improve
compression efficiency coming this year? I'll be re-encoding my large
collection of videos soon for the last time. I've done it 3 times, and
they're not fun. I don't want to do it again (at least for a long time)
because the x264 developers did some black magic :) making x264 a lot more
efficient compression wise right after I finish, which happened 2 times.

Encoding lossless defeats the point of reencoding wouldn't you say?

 

I'm encoding for a portable media player. Efficiency is key.
