Vincent, the reason Blackmagic Cinema Camera can't do 2.5k is because Apple owns the prores codec. In order for Blackmagic to utilize a non existent 2.5k prores, they would have to purchase an annual rental license, plus additional costs for 2.5k prores support and creation and integration. So were talking about millions of dollars. #CommonSense.
Lol. Read outside the box :)
This video at 10k just proves just how important color science is. RED Epic, Gh4, Canon etc, all those companies can develop resolution on their cameras all they want...they will never come close to Kodak, Alexa, or Fuji's beautiful colors. This looks like garbage.
