“True, but still, even though PPro is designed to work in “real time” more so than AE, it doesn’t all the time.”
I don’t think I said anything about Premiere Pro, so I’m not sure what your point is here. AE uses a proxy workflow because it’s (sometimes) the only way to work with a complex composite. AE artists don’t (or shouldn’t) expect realtime playback of heavy projects at full resolution.
“Have you tried PPro with a capture card yet? Adding filters and effects to 4k or 4k raw footage isn’t exactly real time, unless you have CUDA, which doesn’t work very well with capture cards on a Mac. So it’s not all roses and pancakes.”
Yes, I use PPro with Blackmagic capture cards for all editing projects. I haven’t worked with a lot of Red footage, but when I do, it’s a pretty smooth experience. It’s about equal to editing H.264 @ 1080 24p. I can add filters, stack graphics and audio without major playback issues. Though I must confess, I haven’t had to cut a heavy 4K RAW project yet. Then again, I’m not a Mac user so my user experiences may be different.
“Having a proxy workflow in PPro would make much more sense to me as with AE…”
You actually can use a proxy workflow in PPro, this has been possible since the Premiere 6.5 days, it’s just not “built in” the same way it is in AE.
“…everything needs to be RAM previewed anyway.”
Yup, because it’s a completely different kind of tool. With Motion Graphics/VFX work, you don’t expect to work in full resolution in real time.
