Dve Transitions - Blackmagic Design Atem Mini Installationsanleitung

DVE Transitions

Your ATEM switcher includes a powerful digital video effects processor for DVE transitions.
A DVE transition displaces the image in various ways to transition from one picture to another.
For example, a DVE transition can be used to squeeze the current picture off screen revealing
a new video under it.
To perform a DVE transition on the ATEM 1 M/E Advanced Panel:
1 On the preview bus, select the video source that you want on the program output.
2 Press the DVE transition type button to select the DVE transition. The DVE settings will
appear on the LCD menu.
NOTE If the DVE is already being used in an upstream key, the DVE transition type will
not be available for selection until the key is taken off air and off next transition. Refer
to 'sharing DVE resources' later in this section for more information.
3 In the DVE LCD menu, use the soft control knobs and buttons to configure the DVE
parameters. For example, select the DVE pattern and movement direction, and adjust the
DVE transition rate.
4 Perform the transition as an auto or manual transition using the auto button or fader bar.
DVE transition parameters
DVE Rate The duration of the DVE transition in seconds and frames. Rotate the DVE rate
knob to adjust the DVE transition rate. The new rate is immediately displayed in the
transition rate window in the transition control block.
Symmetry Symmetry can be used to control the aspect ratio of the pattern.
For example, adjusting the symmetry will allow you to change a circle into an ellipse.
Symmetry can be adjusted using the z axis of the joystick.
Position If the wipe pattern has positioning then the joystick on the external panel or the x
position: and y position: boxes in the transition palette of the software control panel
can be used to move the center of the pattern. Moving the joystick dynamically
updates the x and y position display in the software control panel.
Normal The normal direction for closed patterns such as circles, diamonds and boxes is to
grow from the center of the screen and progress outward.
DVE key parameters
Enable key Enables/disables the DVE key. The DVE key is enabled when the
button is illuminated.
Pre Multiplied
Select the DVE key as a pre multiplied key.
Key
Clip The clip level adjusts the threshold at which the key cuts its hole. Decreasing the
clip level reveals more of the background. If the background video is completely
black then the clip value is too low.
