I need to capture some green screen shots with a Sony EX1 and I want to use a Decklink SDI.
I noticed Media Express allows capturing to DPX.
I had originally planned capturing the 1080p 10 bit 422 from the EX1's SDI to ProRes HQ, but it seems Prores can be noisy and I have heard of people pulling better keys with normal XDCAM footage than ProRes because of the noise.
So I'm wondering if I'm better off capturing to DPX with Media Express?
Are there any issues with that? Any reason why i would be better of with Prores HQ?
Will I need a raid to capture to DPX?
