Video encoding with 10+ passes

[fibonacci]

I just wondering, would the dvd video quality better if i encoded with 20 passes of cce than 10 passes? or worth it anyway encoding video with more than 10 passes::

More than 3 passes are overkill IMO with CCE. This has been discussed many times in the past.
But of course you could do some test encodings and compare them. If the result is worth to wait a few days for a DVD encoding go for it :p Would also be useful if you don't have to pay for electricity...

I found 10 to make "busy" scenes very messy.

I did a small test with a scene from Cutthroat Island (Blu-ray to DVD).
The scene was a ballroom party with thousands of people. (lots of edges)
More than 3 or 4 just produced a lot of noise and didn't look pretty.

When zoomed in to the max on MPC-HC.

But then, with CCE, there's other options you can play with other the number of passes.
Which require a lot of testing.

In fact, at one time the CCE manual stated clearly that anything over 3 passes didn't show a difference -- but in the later releases they removed that note. In reality everything needed to make the best backup at a given bitrate can be obtained in two passes -- one to collect the information needed, and one to use that information for final encoding. There is a word for CCE passes over 3 -- placebo.

no need to wait days:) i encode dvd9 to dvd5 with 15 passes no more than 2 hrs:)

so would 25 passes improve upon 20 passes or not?
