Detailed Description

Parameters specific to video padding.

Note

The padding is applied inside the output frame at the expense of the usable frame area.

Example: Transcoder input settings: Input frame resolution: 640x480, output frame resolution: not specified, padding as follows: top(60), bottom(60)
Transcoder result: The output frame is 640x480 because the input resolution is kept implicitly. The padding is applied inside the 640x480 frame and the usable frame area becomes 640x360.

Note

Padding is done after cropping.
