Avid Guide for AMA Workﬂow

QuickTime

What happens if… My QuickTime movie has an Alpha channel?

Alpha channels are not currently supported. If you perform a QuickTime AMA link to a movie with an Alpha

channel, you will see the ﬁll only, without the Alpha cutting it. There will be no warning that the Alpha is present,

but will not be used.

To use the Alpha channel, you can still perform a FILE > IMPORT (after setting up your Import settings to

ensure proper handling of the Alpha channel).

What happens if… I move the QuickTime ﬁle to which I have linked clips?

If you move an AMA linked QuickTime ﬁle, it will become ofﬂine in your project. The link to the QuickTime ﬁle is

established by the ﬁle’s name and location. If this happens, here are three things you can do to ﬁx this situation:

• Move the QuickTime ﬁle back to its original location and it should relink automatically; if not, close and reopen

the bin to refresh it and reestablish the link.

• Relink to the moved clip in its new location—open the original bin that contains the ofﬂine clip, select

the clip, chose FILE > RELINK TO AMA FILE(S)…, and then select the QuickTime movie ﬁle

in its new location; this will not create a new clip in the bin, but instead re-establish the link with the

clip already in the bin

• Create a new link (and clip) to the moved QuickTime movie; in any bin that does not already contain the

original clip, choose FILE > LINK TO AMA FILE(S)… to create a new clip of the moved QuickTime

movie in its new location—the original clip remains ofﬂine
