AVS Code Order: Does It Matter?

[Krisqo]

Okay. I just didn't want this footage to stand out when I plug in clips from the cleaner third opening of CCS. I mean, it looks a helluva lot better, but I was afraid it would look weird. I'll tweak some more and see what the final product looks when the mep is released at some point.

The reasoning there being that if you sharpen before smoothing, you are effectively sharpening the noise, making it even more difficult to remove.

I guess that makes sense. Thanks.

Short answer, more general than the ones given above, and perhaps more applicable:

Noncommutative operations.

???

For any real numbers A, B where A, B nonzero, A - B != B - A.

Same idea, except that you substitute "real number" with "video clip" and "-" with "video filter". Just keep that in mind when you're trying to decide whether or not something is commutative.

For any real numbers A, B where A, B nonzero, A - B != B - A.

Wrong condition. Must be: where A, B not equal. Or, if you desperatly want to have nonzero in it: where A-B nonzero.

So:

a-b!=b-a = Video Clip (filter) b! = b (filter) Video Clip

but what does b! stand for? Is it just there or some type of variable? I suck at math, btw.

"!=" is a common notation for "is not equal to". The ! goes with the =, not with the b.

Oh... okay. I get it now. Duh, I forgot seeing that used in my programming class last semester. Shows how much I paid attention.

So it reads

Video ClipA (Filter) Video ClipB != Video ClipB (filter) Video ClipA.

Thanks Scintilla.
