-------------------------------------+-------------------------------------
Current colorbalance filter only works in RGB space.
This can have significant visual differences in the piping filters order.
For instance, on a
Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1920x1080, 17008 kb/s,
30.01 fps
- vf lut=y=gammaval(0.65),colorbalance=bh=-.1:bm=-.1:bs=-.1
Is very different in quality result from
- vf colorbalance=bh=-.1:bm=-.1:bs=-.1,lut=y=gammaval(0.65)
