Ignore this setting unless you have SCTE-35 markers in your input video file. Choose Passthrough if you want SCTE-35 markers that appear in your input to also appear in this output. Choose None if you don't want those SCTE-35 markers in this output. When your input is an HLS manifest, choose Manifest cues to pass through CUE markers in your HLS manifest as segment boundaries and SCTE-35 markers in this output at each EXT-X-CUE-OUT splice point in the input manifest.
