Speed and duration?

I still do not understand how to drop different frame rates into different time lines. I asked and didn't get any responses. Anyway, I usually shoot 720 60p and just change the speed and duration. How is that different than dropping 60p into a 30p timeline (whatever that means)? Again, sorry for the newbie question, but I'm new.
 
In Final Cut, you can simply drop a clip with one frame rate (eg. 30p) into the timeline with a different frame rate (eg. 24p) and it'll automatically adjust the footage (in this case, by dropping frames). It could be the same in PP but I don't know.
 
Thanks!

Well I tried over at the PP forum and not one reply. I guess my question has everyone stumped. It just can not be that diificult of a question!
 
Right click and interpret the 60p footage in the clip bin as 30p. Disable frame blending for the clip. This will give you 50% slow mo

This is different than changing speed/duration or time remapping. When you do this type of change on a 30p clip, you have to resample new frames (you don't have 60p footage so new frames have to be generated somehow as if you overcranked on the camera). So either new frames are generated from blending, or frame repeats, or generate new frames (pixel motion). If you have clip blend enabled, you will get blends (ghosting from combining frames), if you disable, you will get frame repeats (jerky playback). Pixel motion will generate artifacts from motion vector errors. Because of these drawbacks of speed changes in post, this is why shooting a higher fps is always better for slo-mo.

Thank you very much PDR!
