To cut to the chase, I have no idea how to use alpha transparency well in Macromedia Flash 8. I can do simple things like fading in and out or an X-ray effect.

What I'm asking for is if it is possible to remove the background of an object (a sprite in this case) like how it'll appear if played in a game but this time on a video, in Flash 8 or even Macromedia Fireworks 8? I've already tried the magic wand tool, the results weren't what I'm looking for.

The reason I'm asking this here is because the tutorial Adobe provides, shows me what I already know and how to create an alpha channel in a video placed in flash. I'm not placing any videos into flash, though it does seem like it could be an alternative should what I'm asking for be not possible.

Here's a picture with the background.

Here's with the magic wand at 0 tolerance.

Here's with the magic wand at 85 tolerance.

It may seem like I've already solved my problem, but I don't want to lose any of the last lines of color as shown in the 0 tolerance picture. Just throwing an alpha mask on that does not remove the dark colors, which I want to keep for the sake of quality.

In short, is it possible to keep the dark colors without them showing up so badly in an alpha mask or do I have to remove them?

Actually, I'd like to know this too, as in "Is there a way to set progressive transparency to black(ie : Black is completely transparent, and the closer a color is to black, the mor transparent it is ; white is completely opaque.)", if you see what I mean.

It's possible in Photoshop. You can set layer styles.

To do it, have a transparent layer /below/ the layer with that image.
Then select the topmost layer, click the dropdown that says 'normal', and choose 'darken'
Pure black should become transparent, 50% black becomes 50% transparent, etc.
