Remove black bars (matte) from the video
Channels with only one layout and only one source by default use the aspect ratio of input signals when the
output is streamed. If an input video signal doesn't match the encoded frame aspect ratio, bars are added to
the sides or top and bottom of the encoded stream when the output is streamed and recorded.
If you see bars on your output but would rather have the image fill the whole screen, you have to options:
1. Change the output frame size to match the aspect ratio of the input, see Match output frame size with
aspect ratio of input signal .
2. Stretch the image to fit the output frame size aspect ratio, see Stretch the image .
The color of the bars (matte) is defined by the Background color that is selected using the custom layout
editor for the channel, see
Custom layout configuration .
For example:
l
Input signal resolution is 720×480 (a 3:2 aspect ratio)
l
encoded resolution is 640×480 (a 4:3 aspect ratio that is narrower than the input resolution)
Borders are added to the top and bottom of the image to preserve the wider ratio of the input.
