multiple fps in same project

Hi folks,
I'm new here and have a question about editing packages with more than one fps rate.

Lets say I shot footage at 1080p24 and my buddy shot the same event at 1080p30. Can you mix the two into the same project in Premiere CS4? Will there be any issues involved?

I normally shoot everything at 1080p24 for the sake of consistency. But every so often I run across an outlier who shoots at a different fps rate :)

Maybe you are already aware of this, but -

Everything will be conformed to the project settings in Premiere Pro. In this case you must specify one frame rate and all other frame rates will be conformed (converted) to this setting.

You need to test whether the footage looks good - when your friend's is converted to yours or when yours is converted to his. It's a subjective thing. It also depends on what you are outputting to, and what your final (delivery) format will be.

Hope this helps.

My gut tells me that converting 30p to 24p or vice versa isn't going to look too nice. If I had to do it, my inclination would be convert both at 720p60. Maybe 1080i60.

In Encore, timelines can have end actions that point to other timelines. AFAIK, the timelines don't have to be of the same format. Consequently, if all you're trying to do is basically create a video slideshow, and if all of your formats are, e.g., Blu-ray compatible formats (which 1080p30 is not), then one ought to be able to simply daisychain timelines like this without changing the resolution or framerate (adding a dips to/from black on the ends of the timelines might not be a bad idea so as to avoid anyone noticing the short transition delay), however a presentation like this is probably not what you're after. :)

I've been using Grass Valley's Edius for years and easily mix frame rates, image dimensions and filetypes without conforming or transcoding anything.
The current exception is the newest Nikon .mov files.
Otherwise, it's pretty easy.
