Problem with Garbage Matte in Final Cut Pro v6.0.4

[Jerry Hofmann]

Might export them as self contained QT movies, then dissolve between these exported files after you replace them them all matted correctly.. Also might try putting them over each other in their own tracks and use opacity changes to create the dissolve that way…

Thanks Jerry! I appreciate the quick response. I’ll give your
suggestions a try and let you know what kind of success I had.

Is this after rendering? And if it is , are sure you have turned on the ‘full’ option for rendering in your Sequence > Render All and Sequence > Render Selection menus?

Thanks Jeremy.

My rendering options are set as you have suggested and I have
made sure everything is rendered correctly. As I went back over
the entire timeline I have noticed that the garbage mattes I
applied to video clips are doing the same thing. As the dissolves
take place there is a hard edge around the matte instead of a nice,
feathered soft edge. When I remove the dissolve and look at the
mattes the feathered edge looks perfect. It’s something about
the way the dissolve is working with the matte for some reason.

Cool, then follow Jerry’s great advice. I seem to remember somewhere that the alpha channel is hobbled in some transitions, but that is in a distant fragment of my mind.

The technique that Jerry laid out of using separate tracks plus the opacity adjustments should cure it.

[Mike Jensen]

Thanks Jeremy. I went ahead and tried putting the shots on
separate tracks and using opacity changes instead of dissolves and
it worked perfectly. Thanks for your help as well.

Jerry,

BULLEYE! Putting the shots on separate tracks and using opacity
changes instead of dissolves fixed the issue. It would be nice if
I could use regular dissolves…. but the work around doesn’t take
that much longer to create. Thanks again for your help!

I had this problem some time ago and got around it by changing the Alpha Type of the clips. I don’t remember, offhand just what I changed from to what, but you might try changing the Alphas from whatever they are to another type and see if that helps after rendering.
