Timecode in Ultra is relative to the beginning of the clip or the overall session. The timecode
of the first frame of an untrimmed clip or scene is always 00:00:00.00.
Tabs
This section describes the tabs that appear below the Input Preview Monitor and Output
Preview Monitor.
Keyer tab
The Keyer tab consists of the following controls. The Matte Generation, Color Control, and
Post-Processing controls are used to fine-tune the key. For more information, see
“Fine-tuning
the Keyer settings” on page 84
.
General controls
Enable:
Turns the keyer on and off. The keyer is automatically enabled when you click the
Set Key or Apply Points button. If you want to see the unkeyed input clip in the scene, you
can deselect Enable to disable the keyer without losing any of the settings. For more
information, see
“Setting the key” on page 76
.
GPU Boost:
When enabled, Ultra uses the graphics processing unit (GPU) for some keying
functions, which reduces the load on the CPU and substantially accelerates previewing and
exporting a keyed session. For more information, see
“Keying methods” on page 76
.
Set Key:
Clicking this button when nothing but the keying background is visible in the Input
Preview Monitor calibrates the keyer using the Set Key method. If you set any points in the
Input Preview Monitor, then this button changes to the Apply Points button. For more
information, see
“Set Key” on page 78
.
Apply Points:
If you set any key points in the Input Preview Monitor, then clicking this
button uses those points to set the key. For more information, see
“Setting Key Points (Apply
Points Method)” on page 79
.
Clear Points:
This button deletes all key points that were set in the Input Preview Monitor,
regardless of whether you’ve applied them yet. This does not clear the key so that the
background becomes visible again; the only way to accomplish that after a clip is keyed is to
disable the keyer by deselecting Enable. For more information, see
“Multiple Key Points
Method (Color Spread)” on page 80
