CinemaDNG requires a very fast connection for editing -- at least 185 megaBYTES/sec. sustained read speed. Even USB-3 is too slow to do that on most systems. It requires SATA-2 or eSATA-2 at a minimum, preferrably SATA-3 or eSATA-3, or better yet: Thunderbolt.
Thanks Peter,
Do i then understand you correctly, that i can connect the camera (with SSD inside) via the THUNDERBOLT connection to edit/transfer files?
No, the BMCC can't currently act as a SSD reader for a computer. In other words, footage that has been recorded onto a SSD is not transferrable from inside the BMCC to a computer. Instead, to transfer footage from a SSD, put the SSD in an appropriate drive dock/caddie device connected to a computer. The faster the dock/caddie's interface (Thunderbolt is fastest, USB-2 is slowest), the faster the files will transfer to the computer.
The BMCC
does feature the ability to output
live (not pre-recorded) full-quality video for capture via Thunderbolt using the included Media Express software, as described in the BMCC user manual PDF:
http://www.blackmagicdesign.com/media/4 ... Manual.pdfAnother method, is to
play footage from a SDD in the BMCC and capture it to a computer using the camera's 1080p HD-SDI output. This requires a computer with appropriate HD-SDI capture hardware & software or an external recorder (such as BMD offers). Since the BMCC HD-SDI output is 1080p, both 2.5K CinemaDNG and 1080p ProeRes/DNxHD footage is output @ 1080p resolution.
Because the BMCC HD-SDI output is always "live", it can also be used to capture to a computer or external recorder @ 1080p regardless of what format the BMCC is recording to the SSD. So, for example, the BMCC could be recording CinemaDNG 2.5K to the SSD, while at the same time an external recorder attached to the cam's live HD-SDI output records the 1080p signal. The HD-SDI output can be set to either "Film/log" or "Video/Rec.709" gamma.
