Frame rates newbie: 24? 23.98? 30? 29.97? why does it matter?

Apologies if wrong forum! Using FCP7 if that cuts me any slack.

So Mr SD 29.97 (me) has stepped into the Deep end of HD with a new RED Scarlet. (finally putting beloved BWU400 Betacam to rest).
Everyone seems pretty hep on 24/23.98P recording frame rates regardless of final output, in my case mostly commercial/corporate - from which most commercial broadcasters seem to want 1080i files.

I get that Progressive is the way to go, but I have gone over the cliff a few times trying to (accidentally) mix my old 29.97 templates (eg Motion) with my new 23.98P footage. Is there any reason I could not shoot 29.97P instead? Am I screwing myself with Stock Footage and other future-use applications by shooting 29.97 vs 23.98

AND:
what advantage/disadvantage of 23.98 vs 24 - 29.97 vs 30, etc.?

Obv I can tailor specific frame-rates to external clients (ie network TV shows etc.) ,but this is more for my own in-house direct client purposes.

with thanks

23.976 (aka 24p or 23.98) is one of those versatile frame rates: it will work at 29.97 and it can be conformed to 25 with minimal changes in speed; you have to futz with the audio pitch and sample rate a bit, but that isn't a big deal.

24 frames/sec? I wouldn't fool with it unless delivery specs call for it. It's pretty useless for anything other than a film-out.

Now, personally, I think 720p 59.94 is the way to go because it's even more versatile: it's easily converted to 1080i, 30p, 29.97i SD, and 24p, and the 24p can be conformed to 25. Pretty nice, if you ask me.

Hi Dave - thanks. so understood re: 24. Suppose the same for 30fps too. Good tip on the 23 to 29 audio pitch!! :)

720P. Really? gads. My Scarlet bros will have my hide if I run this thing down that far! Get enough "grief"
"just" running HD!

Well, if your new camera happens to shoot 59.94 at a higher resolution, you'd be okay. But it's certainly no mystery that you'd shoot the frame rate appropriate for the task at hand. It's just that 59.94 is the most flexible of them all, in my book.

Thank you Dave. Lots to learn here. :)
Where I can, I would certainly shoot rates that suit a particular application. Big trick is any one ad we produce goes to, say, 4 diff stations and each has a different spec! So I am trying to shoot/edit on the most flexible "base" that I can then generate alternate rates too.
So it sounds like EITHER 29.97 OR 23.98 would work? Does not sound like there is a quality difference between them as far as changing to other frame-rates. Have to say I am partial to 29.97 given a choice.

The choice then becomes one of taste, I guess. Some people are just in love with the more film-style motion of 23.976. 30P is also good for that, in my opinion. And some like the more real-looking motion of 59.94.

One consideration: if you shoot 59.94 P -- if that RED camera of yours is capabile of it -- you have the option of no-brainer slow motion. If you're cutting at 29.97, you can conform 59.94 footage to 29.97, and it's half speed and full image quality. If you cut at 23.976, and conform to that rate, it's 2.5 times slower at full image quality.

Even though I stumbled across this post, I wanted to thank Dave for providing the information needed. The production team recorded at 23.98 and commercials should have been shot at 29.97 to meet broadcasting specs. - Again thank you!

From the lady who freaks out when things go wrong on large project assignments.
