Tune for animation
Many encoders, including aomenc, x264, and x265 have a --tune=animation
or similar option for 2D animation. This would be a nice feature in SVT-AV1. Letting it be a number would be fine, I guess, but a more human-friendly interface would have string possibilities for the --tune
parameter: psnr
, vq
(or psy
), and animation
. That would allow for future tuning possibilities (such as VMAF
).
I have heard from a number of different people that --tune=0
does not play well with 2D animation. If that is the case, perhaps the documentation should reflect this as well. Or if there are other parameters that should be used, it would be nice to have them in the documentation...at present the section describing encoding animation is not all that helpful. I would be happy to do the writing if someone can tell me what should be said.
