Avisynth: Detect Scene Change and Temporalcleaner ?

[NismoSX]

With the new optimal script, should "Detect scene change" in TMPGEnc be activated or not?

And a question for DialHot: What is the suggested TemporalCleaner values to be used? Up to now I've been using this:

temporalcleaner(fmin(round(3+nf), 7), fmin(round(8+nf), 15))

But I see in one thread that you mention this line:

TemporalCleaner(6+nf,13+nf)

Which one is preferred?

[Dialhot]

First, you're right to use "round(xx + nf)" because I forgot that in the official script, nf is a float value and I use a int value (nf = round(YDifferenceToNext()).

Second, the default values for temporalcleaner are (5,10). With your values (round(3+nf) and round(8*nf)) you are always _below_ the default value.

For my part I always find that this filter is better used with values (7,15), so that why I decided to used (6+nf,13+nf) in my MA script.

To make it short : I find you values a little too low. I you find mine two high, I suggest you :

temporalcleaner(round(4+nf), fmin(round(9+nf))

Note: nf can't be more than 2 when we reach "temporalcleaner", so the usage of fmin is useless as long as we don't reach the filter limits that are (10,15)

Ok, thanks a lot!

Hi ren,

No, it should now be checked
We found out it's far better quality, because the GOP is variable in size up to MAX frames per GOP. With the setting "Unchecked", it's always a fixed length GOP, and quality suffers on some scenes
