Introduction to Use of the PR-80
Dual Stream
You can play back two pieces of video material simultaneously, and switch between them.
1.
Click the [Dual Stream] button to change to the Dual Stream mode.
In the Dual Stream mode, video is played back on two channels: MAIN and INSERT.
The palette for the clip played back on the MAIN channel is red. The palette for the clip played back
on the INSERT channel is blue.
The video that was playing before you entered the Dual Stream mode is played back on the MAIN
channel.
You can also switch the Dual Stream mode on and off using the [Insert] key on the keyboard.
2.
Select the clip played back on INSERT.
You can change the MAIN and INSERT clips. Click the Preview Window for the clip you want to
change (MAIN or INSERT) to display the text "MAIN" or "INSERT," then select the clip.
3.
Move the T-bar slider to change the video.
The mixing ratio is shown by MAIN:INSERT under the T-bar slider.
You can select the effect used when switching. Choose the type of Composite FX (compositing effect)
you want.
M:
Moving the T-bar slider mixes the video.
White: You can overlay or perform compositing by making the white areas
transparent using the White (W) Luminance Key.
Black: You can overlay or perform compositing by making the dark areas transparent
using the Black (B) Luminance Key.
* You can set the level for the luminance key using devices such as a DV-7DLC or MIDI controller, or via the RS-232C interface.
For more information, refer to “Controlling Presenter with MIDI” (p. 88) or “Using Other Devices to Control Presenter” (p.
100). When this is not set, the luminance key level has a value of 0 (zero), and the results of luminance-key compositing are the
same as mixing.
You can end the Dual Stream mode by clicking the [Dual Stream] button a second time. When you
do this, the video displayed in the MAIN Preview Window continues to play back.
When the T-bar slider is at an intermediate position, the picture whose ratio is larger (MAIN video
or INSERT video) continues to be played back.
These are displayed
when the [Dual Stream]
button is lit.
