A quickie..

When using
Code:
BB_Resolution = 352 * 480

BB_StrengthConstant = 352 * 240 * 20
StrengthValue = round(BB_StrengthConstant / BB_Resolution)

BlockBuster(method="noise", detail_min=1, detail_max=10, variance=1, cache=1024)
BlockBuster(method="sharpen", detail_min=20, detail_max=90, strength=StrengthValue)
for BlockBuster, do I want BB_Resolution to be the resolution that the movie WILL be encoded at (ie: 352x480), or the resolution that AviSynth is feeding to TMPGEnc after AviSynth cropping and before TMPGEnc resizing (ie: 480x279 or whatnot)..?

I'm assuming the latter (resolution of the image being sent to TMPGEnc) as this makes more sense.. but I just wanted to double check =)

Thanks!

I believe this is the right one.

...which raises an interesting point. When using TMPGEnc resizing you're significantly altering the noise added by Blockbuster, because it should really be used after the resize.

Hmm, so I should resize in the .avs first, apply BlockBuster, then just use Center for the video arrangement in TMPGEnc.. got it. I thought that the resizers in AviSynth were better though, so the resulting file size is bigger..?

As far as BlockBuster goes, I guess I don't understand how the filter works completely then.. why would you want to use the resolution the TMPGEnc is encoding at? Wouldn't that be irrelevant as far as the image the filter works with is concerned?

The way I understand it, the frameserver (AviSynth) is applying the filters before it even gets to TMPGEnc, so why would you use the end/encoded resolution instead of the resolution of the image it (AviSynth) is actually working with?

Again, maybe I just don't understand how it works.. please explain the logic =)

In the meantime, I am going to try simply using
Code:
BlockBuster(method="noise", detail_min=1, detail_max=10, variance=1, cache=1024)
All by its lonesome to see what kinds of results I get. Or would I be better off using the sharpening as well?

Thanks again for all your help -- much appreciated

You can now use:
Code:
BlockBuster(method="noise", variance=1, seed=1 )
Because the default min and max you used are already the default values. Also you don't need to use the "cache=1024". There were some bugs related to that, and SansGrip fixed them.
Check the docs on the latest version of Blockbuster.

I believe the whole BB_Resolution thing only applies to the sharpen method. It's kwag's (very clever) way of varying the strength of the sharpen according to the resolution. Blockbuster knows nothing of BB_Resolution -- the only thing it cares about is the value you give the "strength" parameter.
