The Blackmagic Camera 6.2 update is now available as a free download on the Blackmagic Design website, which extends the Pocket Cinema Camera 4K - as already announced - with the recording option ;)
Blackmagic RAW works (like ARRI RAW) in nonlinear 12-bit space with variable compression rate. The user can choose between a constant bit rate recording of 3:1, 5:1, 8:1 and 12:1 or a constant quality recording of Q0 and Q5. Q0 and Q5 use variable bitrate encoding, so complex frames are encoded at higher data rates. In extreme cases, over 2 hours of Blackmagic RAW material can be recorded in 4K on a single 256GB SD-UHS-II card. Blackmagic RAW is optimized for fast decoding, so that both GPU and CPU cores of a computer can be used. This means that the material can usually be cut fluidly even on weaker systems. Blackmagic RAW even supports frame-based metadata, allowing customers to access values such as focus distance, which often change frame by frame. The new RAW recording can be made with up to 4096 x 2160 in 4K DCI and thus fully exploit the sensor width of the Pocket Cinema Camera 4K with a crop factor of approx. 1.9. ;) But what is noticeable in the screenshots: The recording in CinemaDNG seems to be omitted with the new update. This is not irrelevant because it significantly changes the debayering behavior with the new RAW codec. The look of CDNG was not necessarily worse, but more "direct", closer to the Sensel grid. If you want to mix old CDNG recordings with upcoming ones, you might want to wait with an update.  more infos at bei www.blackmagicdesign.comdeutsche Version dieser Seite: Blackmagic RAW für die Pocket Cinema Camera 4K ist da -- CinemaDNG fällt weg |
