Each broadcaster and distributor will have its own deliverable spec sheet. I have a stack of them, some of which run to book-length. ZDF’s Guideline gets to 78 pages.
There are really three frame bases for deliverables: Universal (23.98), International (50i) and Domestic North American (59.94i) with some variations.
Check with the broadcasters what the video level tolerance is. Usually Resolve does take care of this, but if you add anything in an NLE such as graphics, all bets are off.
Generally, broadcasters want “0” VU, which corresponds to -20dBm on the FCP timeline. Simkplay cranking everything down is not a good solution, as it destroys the dynamic range which your mix might have had. A professional mixer will try to keep as much SPL as possible and then compress for peaks.
The FCC fines overages.
If you are asked for MXF, then Quicktime is out. Sometimes you can wrap Apple codecs in MXF, but 10 times out of 10 they will either want DnXHD or XDCam VBR 50MB/s. It will be in their spec sheet.
Sounds like you are being asked for an XML metadata file.
Fill out as much as you can — if you miss something like the Aspect Ratio code, then there is a risk that your project will not get to air the way you want it to.
