Title: RE: Quicktime Imports

Mark,

Thanks for your help.   I am using version 7.0 .   Using a composite container worked and I'm going to try to link instead of re-creating the media.  I didn't  think of that.

We do a lot of work with Alpha channels (embedded keys). We are using
version 7.5 software, QFE 3 and how you handle keys is largely dependent on
your version.

Here is one way to deal with what you're having problems with...

You do the import and you see the background used in your animation where
the key ought to cut the hole. (by the way, we tend to link to these
Quicktimes and not re-create media once the media is on our local drive
array). If it is screwed up, Delete the clip and all media. Then click on
your capture icon (it looks like a butterfly net), look down towards the
bottom of the dialog and check or uncheck the box marked "Premultiplied
Alpha" depending on how you have it checked by default.

Then re-link or re-capture.

Your key ought to work.

Another way is to put the clip on the timeline (messed up) and from 7.5
software on place it in a Composite Container. Then, inside that container,
drag a Composite Node onto your tree, click on the channel for that node and
change your pre-multiplication from there.

When you step out of your container (the one with only that clip), the key
ought to work. I've had the odd problem of a DVE being wierd after that --
not clipping things correctly, but that usually is solved by a reboot (not
the BOB).

I am a newbee at DS so I hope my question isn't too basic. 
I am trying to import QT movies that are Premultiplied with AVID Meridian
compression.   They always come in with the alpha channel screwed up and my
work around has been to throw the original QT movies through AfterFX and
re-render them without the AVID Meridian Codec.  Is there a way to correct
these files without going through AfterFX.
