Hello there.

I've set my 600D to NTSC mode since I can get 60fps at 720p, therefore having much more "space" to slow down video. I also aim for the final video to be at 24fps, both for slow-motion latitude and the overall look of the video.

Now, what confuses me is how should the workflow be set. Should I open up a sequence in premiere with a 60fps timebase, and then export at 24fps, or should my sequence be at 24fps (or 23.98) from the beginning, since that's the "look" and frame-rate I'm looking for?
Things get even more confusing when after effects factors in. Most of the times, my project goes through after effects for color correction/grading, through dynamic link. If the correct way to do it is to set the sequence (in premiere) at 60fps to begin with, should the AE sequence also be set at that framerate, and then export at 24?

You missed my question.

There are two points on an editing workflow with premiere, where you are able to set frames per second:
1 - At the start of the project, where you are asked for the timebase of the sequence you are about to start working on.
2 - At exporting, where you can set how many fps the exported video has.

(forget AE for now)

I have 60p files, but it's only for in case I want to slow it down, because I always want the final piece to be at 24p
The question is how should I set my project: 60fps timebase on sequence creation, and then set to 24fps on export, or set it to 24 from the start? Is there a difference?

I discourage you to go 60p>24p, it will never look good, thers simply no way to do it without having to compromise. It will look better at 30fps.

Anyway use a 24fps project and export as 24fps, for the slowmo clip use modify>interpret footage>assume framerate 23,976 for slowest smooth playback.

edit. Tried that method and yeah it looks like shit, its very choppy. You can try it for yourself and see, if you dont like it try something with frame blend.

Many, many thanks.

And I might also stop using the 60p recording by default, considering memory space too.

Best regards!

I've done experiments with twixtor, and yes, background matters.
Some mixed results, but it worked for the most part:

I can't remember if I had changed PAL to NTSC by that time, but yes, either 50 or 60p.

Many thanks for your answers!
