50i and 60i in the same project?

You can have some softness or ghosting in areas of fast motion where Premiere Pro has to interpolate frames, but that’s about the only problem. Make sure to enable frame blending to make the frame interpolation the best that it can be.

On Frame blending…if you do any fast/slow motion or time remapping, I’d try a test output before deciding whether to use Frame Blending or not… It can be salvation or damnation completely dependent on content and circumstances.

I’d also recommend that any clips that are in 60i that can simply be run at 50i without harming the content (cows in a pasture, landscapes, etc.) should be simply re-interpreted in the project panel to 50i from 60i. It’s one click and the clips will now even run render free on the timeline and of course, be very clean with no frame interpolation.

I agree with both of Tim’s points.

Regarding the frame blending: Basically, you’re choosing between repeating one frame out of five (which can look jumpy in some circumstances) or blending adjacent frames (which can look like ghosting in some circumstances). Usually, the ghosting is lost in the motion blur if there’s any motion, but that isn’t always the case.

If neither of these works well for you, you have the option of doing retiming/conversion in After Effects, which has a much more advanced set of frame blending options.
