Remove black bars (matte) from the video
A channel with only one layout and only one source by default uses the aspect ratio of the video input source
when the output is streamed. If the input video signal doesn't match the encoded frame aspect ratio of the
channel, 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 can:
1. Change the output frame size to match the aspect ratio of the video source at 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.
For example:
l
Input signal resolution is 720×480 (a 3:2 aspect ratio)
l
encoded resolution is 1280×800 (a 16:10 aspect ratio that is wider than the input resolution)
