Hi,

I recorded a concert with various cameras;
Sony F350 (1080/50i VBR)
Sony Ex1 (1080/50i HQ)
Sony Ex1 (10801/501 SP)... borrowed camera didn't notice the setting at the time...
3 x Sony Z1 (1080/50i HDV)

I've since captured all the material in their respective native formats and am ready to begin editing. In order to use FCP's multicam function however, all footage must be in the same CODEC. Any suggestion how I would go about converting everything into perhaps ProRes422?

thanks
