To Build Background E-MEM Transitions:
When building background transitions make sure the A and B background
bus selections are consistent through out the effect. Otherwise the back-
ground video may cut to different sources when keyframes are encoun-
tered. Plan ahead to the next transition when you create keyframes in an
effect that has multiple background transitions.
1. Go to the keyframe in the effect where you wish the background
transition to begin.
Note Adding new transition keyframes to the end of an effect is the easiest way to
build effects containing background transitions, though using this method is
not required.
2. Select the Bkgd next transition button.
3. Select the type of transition ( Mix , Wipe 1 , or Wipe 2 ).
4. Select the new source to transition to on the B bus.
5. Press Modify to change the keyframe to the values set above.
6. Perform the transition by moving the lever arm or pressing the
Auto Trans button. This lets you preview how the transition will look
(though the transition duration used may not match the keyframe
duration specified).
Note Performing the transition is not required (pressing Cut accomplishes the
same goal, which is to put the switcher into the next desired state). The tran-
sition type button selection and the keyframe duration determines how the
transition will be performed when the effect runs.
7. If there will be another transition immediately following this one, select
on the B bus the source that will transition to in the next keyframe. This
prevents undesirable background cuts from occurring.
8. Press Insert After to add this keyframe to the effect.
9. Repeat the steps above for any additional background transitions.
10. Rewind and run the effect to check its operation. The transitions will
occur as programmed.
11. After the effect runs properly, you can go back and modify keyframes
with Source Holds where needed.
If unwanted background cuts occur, go to the keyframe where the cut
occurs, identify the source selected on the A bus, go to the previous key-
frame, select that same source on the B bus, and then press
Modify KF to prop-
erly setup that source in that keyframe for that next transition.
