@ -7637,7 +7637,7 @@ This isn't recommended and wastes bitrate as scenecuts encoded as P-frames
are just as big as I-frames, but don't reset the "keyint counter".
.
.TP
.B frameref=<1\-15>
.B frameref=<1\-16>
Number of previous frames used as predictors in a P-frame (default: 1).
This is effective in Anime, but seems to make little difference in
live-action source material.
@ -7871,6 +7871,17 @@ In the above, "all candidates" doesn't exactly mean all enabled types:
4x4, 4x8, 8x4 are tried only if 8x8 is better than 16x16.
.
.TP
.B (no)chroma_me
Takes into account chroma information during subpixel motion search
(default: enabled).
Requires subq=5.
.
.TP
.B chroma_qp_offset=<-12\-12>
Use a different quantizer for chroma as compared to luma.
Useful values are in the range <-2\-2>. (default: 0)
.
.TP
.B level_idc=<10\-51>
Set the bitstream's Level as defined by Annex A of the H.264 standard
(default: 40 - Level 4.0).
