Key Modifiers
Key modifiers are used to apply DVE effects or
borders and trails to a key.
DVE Keys (Fly Key)
The Fly Key function is used to apply DVE video
effects to a key. The Fly Key can be applied to
any key type, but will use a different number
of DVE channels depending on the type of key
(video + alpha).

The DVE Menu button on all of the DVE menus allows you
to quickly navigate between the different DVE menus.

Keep the following in mind when working with
DVE keys:
• You can fly any type of key.
