1 first pass
2 second pass
(only need to specify if two-pass encoding is used)
Tip: u can try to use constant quantizer mode for pass1 (vqscale=<quantizer>)
vbitrate (kbits per second) for pass1/2
800 is default

lumi_mask (0.0-1.0) luminance masking
0.0 disabled (default)
0.0-0.5 should be a sane range
warning: be carefull, too large values can cause disasterous things
warning2: large values might look good on some monitors but may look horrible
on other monitors
dark_mask (0.0-1.0) darkness masking
0.0 disabled (default)
0.0-0.3 should be a sane range
warning: be carefull, too large values can cause disasterous things
warning2: large values might look good on some monitors but may look horrible
on other monitors / TV / TFT
tcplx_mask (0.0-1.0) temporal complexity masking
0.0 disabled (default)
scplx_mask (0.0-1.0) spatial complexity masking
0.0 disabled (default)
0.0-0.5 should be a sane range
larger values help against blockiness, if no deblocking filter is used
for decoding
Tip: crop any black borders completly away as they will reduce the quality
of the MBs there, this is true if scplx_mask isnt used at all too
naq normalize adaptive quantization
experimental
