Dissolve without alpha
Hi all
I have had this problem several times. When I use a eight point grabage mask on a layer and I dissolve to or from it, the dissolve also works on the alpha, meaning the opacity changes to zero on the alpha layer as well. any mask that FCP uses then dissolved away, leaving the full mage visible in the dissolve.
I would like to dissolve without affecting the alpha I’ve applied to the track, only the YUV or RGB.
How?
Thanks

Is this a clip that has an alpha channel already? You don’t mean the alpha created by the garbage matte, do you? Because I don’t see that happening. If the clip or image has an alpha already, what kind of image is it?

Hi Tom
No, the clip does not have embedded alpha. I’m talking about the alpha that the 8 point garbage matte creates.
I have found something new about this. If I dissolve to or from nothing (on top of a background layer), I get this alpha problem with the garbage matte. If I dissolve to or from another clip, it works as it should.
go figure…

Try putting the clip in a nest and dissolve to/from the nested clip (or clips).

That’s very strange. I can’t make mine do that. I’m in FCP5.0.2 BTW.
