0 SAD (sum of absolute differences) (default)

1 SSE (sum of squared errors)

3 DCT (sum of absolute dct transformed differences)

4 PSNR (sum of the squared quantization errors)

4 PSNR (sum of the squared quantization errors) (dont use, low quality)
|

5 BIT (number of bits needed for the block)
|

6 RD (rate distoration optimal, slow)

7 ZERO (0)

+256 (use chroma too, doesnt work with b frames currently)
|
||||
Tip: SAD is fast, SATD is good
|
||||
Tip2: when using SATD for full pel search u should use a larger diamond
|
||||
something like dia=2 or dia=4

+256 (use chroma too, doesnt work (correctly) with b frames currently)
|
||||
Tip: SAD is fast, SATD is good, SSE is something in between
|
||||
Tip2: when using SATD/DCT/BIT/RD for full pel search then a
|
||||
larger diamond something like dia=2 or dia=4 might improve
|
||||
quality, but only for some videos
|

Note: mbcmp is only used if hq mode is disabled
