I put together a review of a new added PRORES formats to the Blackmagic Design Cinema Camera 2.5k model. In this test, I compared different formats starting from the DNG and goind down all the way to PRORES PROXY.
For this test I used Only BMCC camera and Sigma 18-35mm F1.8 lens. Grading to REC709 was done in davinci resolve. Output Format is H264 with 50mbs.
