You ur unsure of the deliverables and don’t want to contact all the stations – I would go with BetaSP – SD – Widescreen – Letterbox. Just about all broadcast facilities have/had/still use Beta SP format. It’s Broadcast.
SO, output quicktime movie from your timeline, current settings.
Leave the box “make self-contained” UN-checked – this makes a reference movie file.
Drop the ref file into compressor and make a 10 bit uncompressed SD file.
Re-import, wait, do you have a Card in your edit sys? AJA, Kona? Decklink? Then you could just output a SD copy on the fly…
If not, compress to a SD file w/ compressor. Import new file into FCP, drop into same settings Timeline, edit to tape w/ bars, black and countdown. Times 20
