# DASH output
<a name="dash-output"></a>

DASH ISO output does not support passthrough of the SCTE-35 messages or manifest decoration. Therefore, the only workable option is the default behavior:


| SCTE-35 passthrough | Insertion of SCTE-35 messages | Manifest decoration | Blanking and blackout | Effect | 
| --- | --- | --- | --- | --- | 
| Not applicable | No | Not applicable | No | Removes SCTE-35 messages from the output. The manifest is not decorated. Do not implement blanking or blackout because, without SCTE-35 messages in the video stream and without manifest decoration, it is impossible to find these blanks and blackouts programmatically. |
