Simplify alpha export?
Is it possible to simplify the alpha export options?
Options like shrink, remove bg black, non intense alpha, etc, could they be set automatically? Do other sfx apps have these options? If not, how do they deal with it?At least, how about a way to preview the effects of these options, so the user can learn by testing the effects and get immediate feedback? This beats reading a help page.

Don’t use “shrink” — it doesn’t give great results, and is an older workaround.
The “remove black background” is a way to make a “straight” alpha as opposed to “premultiplied”. Here’s a great video explanation of this by Aharon:

“Create non-intense alpha” is something that you’ll only find in particleIllusion, as it’s intended to work around a problem with the original method of generating alpha channels. The docs explain it quite clearly I think.
