Contents Introduction
Video Layout Scaling
Define how the system shall adjust the aspect ratio for images or frames when there is a difference
between the image and the frame it is to be placed in.
Requires user role: ADMIN
Value space: <On/Off>
On: Let the system automatically adjust aspect ratio.
Off: No adjustment of the aspect ratio.
Example: Video Layout Scaling: On
Video Layout ScaleToFrame
Define what to do if the aspect ratio of a video input source doesn't match the aspect ratio of the
corresponding image frame in a composition. For example if you have a 4:3 input source (like XGA)
to be displayed on a 16:9 output (like HD720).
Requires user role: ADMIN
Value space: <Manual/MaintainAspectRatio/StretchToFit>
Manual: If the difference in aspect ratio between the video input source and the target image
frame is less than the ScaleToFrameThreshold configuration (in percent), the image is stretched
to fit. If not, the system will maintain the original aspect ratio.
MaintainAspectRatio: Will maintain the aspect ratio of the input source, and fill in black in the
rest of the frame (letter boxing or pillar boxing).
StretchToFit: Will stretch (horizontally or vertically) the input source to fit into the image frame.
NOTE: The general limitation is that you cannot upscale in one direction and at the same time
downscale in the other direction. In such situations the codec will apply letterboxing.
Example: Video Layout ScaleToFrame: MaintainAspectRatio
Video Layout ScaleToFrameThreshold
Only applicable if the ScaleToFrame configuration is set to manual. If the difference in
aspect ratio between the video input source and the target image frame is less than the
ScaleToFrameThreshold configuration (in percent), the image is stretched to fit. If not, the system
will maintain the original aspect ratio.
Requires user role: ADMIN
Value space: <0..100>
Range: Select a value from 0 to 100 percent.
Example: Video Layout ScaleToFrameThreshold: 5
