Variable framerates in Premiere

[karapetkov]

I searched for similar topic but couldn't find any here or the Net.

I was wondering what is the best route to insert fast- or slow- motion shots in a project.

For example, I have shot some takes in 50 or 37 fps with the HVX [PAL version] and now I'm editing in a 25 fps timeline in Premiere CS3.

What I do now is slow down the footage speed to match the 25 fps speed.

In this way, a 50 fps shot is slowed down to 50 % and I get the slo-mo effect.

I'm wondering if this is the actual right way to do that? Just with the speed or is there a more established method?

My other concern is with other speeds, for example 18 fps or 12 fps? It's actually not exactly 18 fps but 17.86 fps [or something like that].

If speed adjustment in Premiere is the way, what are the exact percentages for all the standard framerate speeds in the HVX?

I guess this percentages should be very accurate to get the real slo-mo or fast-mo footage, otherwise Premiere starts adding virtual frames and degrading quality of the material.

I hope I have explained my situation clear enough.

Thanks in advance.

Come on people, I'm just a beginner in this field...

I'm a student... not a pro yet.

If you shot at 50 or 37 fps in camera, it should playback at 25 fps in premiere. It has never played back at 60 frames per second when I shoot 60p. Does that happen to you? I'm pretty sure that you shouldn't have to slow or speed up your footage at all.

Also, if you want virtual frames/ramping it is good to use time remapping at the highest quality with after effects (if you have it).

Yes, it plays back at 50 in CS3 and I get the 'reality" look, not the slo mo...

Maybe some settings in Premiere?

I think you're looking for a properties dialog for the clip. It's been too long since I've used premiere but right click the clip and try to change the frame rate from default to 25.

Yes, "Interpret Footage" is the dialog, but it's strange why this doesn't come by default?.... after I've set 25 fps project...
