When video bitrate is set, 2-pass encoding is used for MPEG-4 output.
Hints:
- * Use max. 640x480 pixel size for widest compatibility
- (ie. square-pixel 640x360 or anamorphic svcd_ntsc_wide for 16:9)
+ * Use square-pixel max. 480 width (vga 480p) for widest compatibility.
* Use a modulus 16 profile (qvga vga 480p 720p) for best compression.
- * Append these for single-mic speech: ac=1 ar=32000 ab=64k
* Set bitrate for optimal MPEG-4/WebM bits-per-pixel ratio:
+ talking head: 0.1
+ high-motion or detailed content: 0.15
