Recording Blackmagic RAW
on Video Assist 12G HDR
With 12G video assist models you can record Blackmagic RAW from Canon C300 II, Panasonic
EVA1 and SIGMA fp directly to your video assist. All you need to do is output a RAW signal via
either your camera’s SDI out connection or HDMI out when using SIGMA fp.
Connecting your camera to Video Assist 12G HDR
1 Connect your camera’s SDI or HDMI out to the SDI or HDMI in on your 12G video assist.
On Canon C300 Mark II, you can use either the ‘rec out’ SDI or ‘mon’ SDI ports. On
Panasonic EVA1, use the ‘SDI out’ port and on SIGMA fp use HDMI out.
2 On the video assist, set the codec to Blackmagic RAW and select the quality option
you want to record. For detailed information on the Blackmagic RAW codec options
available, see ‘Recording to Blackmagic RAW’ later in this manual. Now you can set
your camera to output a RAW signal via the SDI or HDMI output.
It’s worth noting that Panasonic EVA1 requires the use of a 6G-SDI compatible cable. For Canon
C300 Mark II, a 3G-SDI cable is fine.
Canon C300 Mark II
1 Click on the ‘menu’ button on the monitor unit to open the menu on the monitor.
2 Using the joystick or touchscreen menu if available, navigate to the ‘recording/media
setup’ submenu and select the ‘rec out 4K RAW mode’ option.
3 Select the ‘4K RAW’ option, this is the only RAW output over SDI option on the Canon
C300 Mark II.
4 Wait for the display to reboot and return to the menu.
5 Now select your color space by using the joystick or touchscreen to select ‘4K RAW
color space’.
6 Select either ‘BT. 2020 gamut’ or ‘cinema gamut’. It’s worth noting that these are
‘baked in’ to the raw output, so selecting ‘cinema gamut’ will offer more latitude in
post production.
7 Press the ‘menu’ twice to return to the monitor view.
TIP To make sure the RAW output is compatible with Blackmagic RAW, the gamma
must be set to Canon Log 2. For more information on setting your gamut and
gamma settings, refer to the Canon C300 Mark II instruction manual available on the
Canon website.
