Although I don't know which way it works -- from full to low resolution or the other way around.

This description, http://homepages.inf.ed.ac.uk/rbf/CV...stimation.html , shows level 0 as one with the full resolution.



Then the description of the patch has this information:



This patch does the following:

1) Perform level-0 ME

2) Use the MVs as predictor for next level ME

3) Restrict full-search within a range when HME is enabled




In these cases, it would be really nice to have a clear explanation in the docs
Yeah, there is not enough info in docs about it.
I'm worried about this http://forum.doom9.org/showthread.php?p=1881016
Is it relevant to the option --refine-mv which is changed to 1 by default for now?

I've done some tests:

--merange 57 --no-hme 2.21fps
--merange 57 --hme umh, umh, star 1.74 fps
--merange 40 --hme umh, umh, star 1.90 fps
--merange 32 --hme umh, umh, star 1.96 fps
--merange 26 --hme umh, umh, star 2.04 fps

So, 27% between HME off and HME on with same merange.
Well, the question is what is better, --merange 57 --no-hme or --merange 26 --hme, cuz defference in speed between them not so much
