Avisynth: Detect scene change and TemporalCleaner ?
 
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:
Code:

temporalcleaner(fmin(round(3+nf), 7), fmin(round(8+nf), 15))
But I see in one thread that you mention this line:
Code:

TemporalCleaner(6+nf,13+nf)
Which one is preferred?

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 :

Code:

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)

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 :)
