DivX 5.1ｷﾀ━━━━━━(ﾟ∀ﾟ)━━━━━━ !!!!!4
ところで、これは既出？

Q: Why does DivX 5.1 encode slower?
A: There's a simple explanation for this
Slowest mode in 5.05 = Standard mode in 5.1 (roughly).
In 5.1, Slow/Slowest modes implement a new algorithm, known as the rate distortion algorithm.
Essentially, the RD algorithm squeezes higher quality still out of any given bitrate
by carefully choosing frame and block types in order to save bits while encoding.
The quality improvements can be quite significant.
↓特にこれ
A performance tip:
Do all but your last pass in Standard mode with the MV file enabled.
Then, disable the MV file (this is imporant) and switch to Slow or Slowest mode for your final pass.
If you use Psycho-vis then you can also disable it
until your second-last pass as long as you disable the MV file at this point
(e.g. if you're doing 4 passes, turn on PV and turn off MV in pass 3).
MultipassにおいてPsycho-visual…を使わない場合は、一番最後のパス以外は
MVfileをチェックしてStandardで、一番最後はMVfileのチェックをはずしてSlowまたはSlowest
にするとよくって、Psychovisualを使う場合は最後から２番目の時点で
Psycho…をON、MVfileをOFFにしSlowまたはSlowestへ移行すると時間を稼げるそうだけど…。
