Hello,
I wanted to ask for some additional options, that I'd find useful.
1. Actually for the closing credits of a film I use the following:
--zones 123456,999999,b=0.5,deblock=1:1,psy-rd=0.4:,aq-strength=0.6
This is just a copy'n'paste of --tune animation, but nothing easy to memorize.
I know, that it's not possible to change all options in the zones (e.g. refs), but how about just taking just the possible ones from the tune-settings.
Could you make it possible that we just type this:
--zones 123456,,b=0.5,tune=animation
Or perhaps even this:
--credits 123456,0.5 including some b/w-optimizations, optimized motion-search with --merange values of horizontal:4 and vertical:256 :devil:
Additionally, because we have got "animation", I wanted to increase b-frames, what doesn't seem to be possible. Is there any technical reason for this?
2. I recognize that using the above zone-line also decreases bitrate _before_ frame 123456, and at some other test reduced bitrate was also also _after_ the zone ended.
Is this intended? To fix this, I also must use the start point of the closing credits + actual key-frame length. So it seems changing the bitrate-factor (b=0.5) is somehow bounded to the "GOP"?
3. Could you please save (and reuse) the index file when e.g. a .mkv is opened?
[info]: indexing input file [27.4%]
x264 is actually indexing again and again, when you use it on the same file, what's very annoying on big files.
Regards,
