Yep,
our FinalDCP is designed to be very streamlined for the average user.
At best you export a Quicktime or AVI file (most codecs like CineForm, DNxHD, ProRes, BMD, AJA etc. are supported) and import into FinalDCP.
Regarding speed:
We have a new professional version of the RenderNode coming, being 4 times faster. That means a single machine can do realtime. On our RenderFarm we tests about 40fps in 4K, 130+ fps in 2K and we are not yet done.
Cheers,
Axel
