25p footage in a 24p movie at DVinfo.net

Hey, I found some great footage that I could use to flesh out my movie - b-roll stuff, but I could use quite a bit of it.

Anyway, the stuff is great - the interviews were shot on the Canon HV20 and the B-Roll stuff on the Canon XH-A1. Just one problem - my HV20 stuff was shot at 24p and the B-Roll Canon XH-A1 was shot at 25p.

How should I integrate this into the final, 24p movie format. Will FCP simply handle the 25p footage and do the conversion at export automagically or should I render the 25p footage to 24p using a different process? I'd rather do a 4% slowdown than a 2:3:3:3:3:8:7:pi:square root of 77:2 process.

Hi Brian.

Don't worry about pulldown. That's purely the realm of NTSC.

Use Cinema Tools. It will slow down the 25p footage to 24p. I believe it also adjusts the sound pitch slightly so that the audio still sounds normal. I use it a fair bit. It's great for 24p to 25p conversions and vice versa.
