the scanline renderer on page 7918 , with the additional options listed below.
The resulting scene image has an
alpha channel on page 7709 .
You can use multiple Scene events to show two views of the same scene
simultaneously or to cut from one view to another. If you have more than
one Scene event in the queue, and they occupy the same time range, composite
them with an
Image Layer event on page 6623 such as Cross Fade or Simple
Wipe. Otherwise, the second Scene Event overwrites the first even though
your system has spent the time processing both events.
Procedures
To add a Scene event:
1 Make sure no events are selected in the queue.
2 Click Add Scene.
An Add Scene Event dialog appears.
3 Choose a view to use from the View list.
4 Click Render Options to change rendering settings from the way you
have set them in the Render Scene dialog.
NOTE Unlike settings in the Execute Video Post dialog, changes you make
to the Scene event rendering options change the settings in the Render Scene
dialog, and vice versa.
5 Set the Scene Range options and click OK.
The Scene event appears at the end of the queue.
To match the scene's frames with Video Post frames:
■ Make sure Lock To Video Post Range is selected.
Lock To Video Post Range is the default. Frames in the scene match Video
Post frames and have the same frame number. That is, frame 0 in the scene
is frame 0 in the Video Post dialog, frame 15 in the scene is frame 15 in
Video Post, and so on. The range bar for the Scene event represents which
portion of the scene is selected. If the range bar covers Video Post frames
25 to 35, executing the queue renders scene frames 25 to 35. Moving the
range bar for the scene is like moving a time window within the scene.
Other Scene Range options are disabled when Lock To Video Post Range
is selected.
