It's true working in 720p is lighter and faster. Heck it's about 900,000 =
pixels vs. 2.2 million in that frame.=20

Having said that, working with 720p in editorial and mastering seems =
like a bad idea to me, unless you are absolutely certain you are okay =
with the future limitations of that.=20

Even though 720 gives room for Pan and Scan of 1080p, you can certainly =
scale up 1080p in a 1080p timeline, especially when you know you are =
going to drop it back to 720p on delivery. It's a wash. (stick to 150% =
and below scale if you want perfect pixel-matching in 720p). Also, using =
Premiere Pro when you need to go larger takes advantage of the best =
scaler in the NLE universe. Better than AE, in fact.=20

When it comes right down to it, if I shot 1080p I prefer to master =
everything 1080p then go to work on deliverables. For example, for =
broadcast 1080 they're going to want 1080i/29.97 (aka 60i). For 1080p =
that's simply a PsF maneuver in your encoder. Perhaps adding pulldown if =
you started with a 24P master.
For 720p it's always progressive so just stay with it. If they don't =
like native frame rates you may have to pad out to 60p (that's the 720p =
baseline deliverable).=20
