I can do that :)
Do you have standard way to generate these figures? (Video, options ?)
Or shall I just generate a couple of figures to put in the commit?

with further downscaling of the lookahead pictures.
The lowres motion vectors are used in weight analysis as well, so that
file would need to be updated.
I'll have a look at it. It

it is slightly more complicated; you'll want to scale up the block sizes
used for motion-compensated weight analysis -
Hi,
We recently profiled x265 pre-analysis to estimate what performance we could
reach using our accelerator and I was quite disappointed by the performance.
When running on a Core-i7 with AVX at roughly 2.7GHz, we barely reached the
30fps mark using ultrafast preset on a 4K video.
After a
Thanks, this is certainly an enhancement to x265 lookahead. We would be
interested in this - especially if you can also include some efficiency
(bitrate vs SSIM) metrics that describe the penalty moving from
X265_LOWRES_SCALE of 4 to higher scales.
