in fcp, for example, it would appear in quicktime as 720×576 and it would be full frame but squashed in. this is how the broadcaster accepts it and then when the ad is aired it appears fine. so i assume when exporting in ppro i’d select the stretch to fill option, but this doesn’t change the output. if i export a 1080 version and then bring it in to media encoder it comes out how i would expect, but i don’t really want to to export and bring back in and export again.
