BlackMagic Intensity Final Cut Pro & PAL

[oceanzen]

So I'm thinking about getting the blackmagic intensity to go in a Mac Pro.

I'll be using a Canon HV20 to shoot green-screen work, going out through the HDMI output to the Intensity's HDMI input.

1) Do I understand correctly, that I will be able to record straight to Apple ProRes422 format? - without having to buy any extra cineform codec?

It should be possible to record 1080i50 with the above set-up right?

2) Is 1080i50 the best recording format for green screen work?

3)Is it better than 1080p25?

And if 1080p25 is better,
4) Can I capture 1080p25 with the above set-up

Thanks,

Ocean
