lost details in x264 at high bitrate?

[cjei]

Is this a known issue of x264 ?


These are captured from a 30s 720p clips encodes at 8Mbps.
source xvid x264

And what settings did you use? I'm just guessing, but for instance the default in-loop filter settings seem a bit strong for such a high bitrate.

A friend in other forum just told me x264 v32* - v384D has a simple AQ patch, with which could solve this at the cost of higher Quan.

[Japhsoncross]

that patch by Haali will reduce Quan for flat areas. it's for the blue sky blocks problem.
and that's not the finesolution for the loss of details at flat areas, i think.

haali's aq strongly reduced details in my tests, together with only being meant as a fix for the blueblock issue (that was fixed otherwise now), its surely not a solution for "lost details at high bitrate"

Would any of the mods mind approving the JPG. I'd like to see for myself.

How about switching the in-loop filter completely off (--nf)?

[Sharktooth]

at 8mbps you cuould use -6,-6 or either switch the loop filter off.

The source frame is different than from xvid's and x264's

Deblocking might not change a thing. What you call details, I call it noise. Ok, the dress is slightly less textured. But the source is mpeg2, and mpeg4 asp does look like mpeg2, while avc doesn't. In that case, I don't mind it because x264's frame has less ringing.

What was the source bitrate, btw ?
