I have a wedding coming up in a couple weeks and I want to use a couple Canon 60D cameras along with my Sony AX2000. This is will be my first experience putting footage on blu-ray, and using DSLR for video at an event. What is the best format to record in for both cameras and will I have to transcode any footage. the Ax2000 is capable of recording in 1080 60i, 1080 30p, & 1080 24p. It would seem to put both cameras set to 1080 30p would be the best, but how would that work with converting to blu-ray since 30p is not a supported format.

Don't know what editing system you are using but I shoot in 30P and just switch to 1080 60i or 1280 X 720 60P for encoding to Blu-ray.

I am editing on Premiere Pro CS5

I don't use Premier but just switch your project to one of the blu-ray spec and encode, if Premiere doesn't allow to do that then you will just have to change the settings inside your encoder.
