Ignore this setting unless this input is a QuickTime animation with an alpha channel. Use this setting to create
separate Key and Fill outputs. In each output, specify which part of the input MediaConvert uses. Leave this
setting at the default value DISCARD to delete the alpha channel and preserve the video. Set it to REMAP_TO_LUMA
to delete the video and map the alpha channel to the luma channel of your outputs.
