Here are the export settings I use to make video what I believe to be ATSC compatible.
ATSC is a set of standards for broadcast video in the U.S., Canada and Mexico.
These settings are conservative. They are intended to be compatible with the largest user base possible, hence the use of the MPEG-2 codec.
User assumes all responsibility for use of these settings.
The audio is PCM which is not ATSC compliant (ATSC requires AC3 audio). These settings are suitable when a deliverable with PCM audio is desired. It is the responsibility of the broadcaster to re-encode the audio to AC3.
