Mixing Multiple Frame Rates Over Many Projects…
I’m producing a project where I will have to deal with multiple frame rates. For example, here is a list of what I mean:
1) My footage will be 29.97
2) Several pre-rendered elements from AE will be in both 24fps and 29.97fps (as these were original templates and are varied across the board, depending on the author)
3) My final destination for the project is YouTube, which from what I understand uses 24fps (confirmation on this?)
So, my question is this; when dealing with all these different frame rates, what should the MASTER timeline be set to? Should it reflect the original source footage of 29.97fps or should I just start at 24fps since this is the destination, even if some of the footage is not 24fps?
Thnx!

Select the framerate of the majority of your footage as your deliverable. Video on the web is nonstandardized, flash and html5 players can take any reasonable framerate you can think of.
What worries me is that motion graphics don’t look as good as photographic footage when you change/blend framerates but since you have a mix of both 24 and 29.97 you’ll trade off either way. If these motion graphics templates don’t go with any audio and you don’t mind a slight speed change, I’d change the frame rate interpretation directly. This will stop dropped or blended frames.

Makes senses…but allow me to pick your brain a bit more on two areas you discussed:
1) When you say change the frame rate directly, do you mean going into the Comp settings of the AE project files and just manually changing the frame rate? If there are certain things timed in the Comp’s timeline, won’t altering the frame rate throw these bits off?
2) What standard frame rate should I settle on? My footage I start with is always 29.97, however, almost all the 1080p settings seem to prefer 24fps (even though 1080p 30fps is always available). Also, YouTube is 24fps.

Youtube is not 24p, you have been given false info on that. Chances are you/they were confused over the fact that 24p is mentioned in their FAQ — it’s only a reference to avoid stuff that has a pulldown applied (film transfer to NTSC for instance). Youtube recommends staying with your native framerate.
1. You can either change the comp framerate and adjust for timing issues (better quality but will throw timing off) or let the chips fall where they may if you let Premiere or Adobe Media Encoder convert the framerate (through a process of frame blending and frame drops/duplications). And yes, to clear myself up, I mean changing to comp’s framerate in AE.
If you’re just going to let Adobe Media Encoder do a conversion, I would suggest turning frame blending off for motion graphics.
2. If the majority of your footage is 29.97, stick to it. No reason to convert the majority of your material since you don’t have to.
