Blackmagic (vuo.blackmagic)

Nodes for working with the video capture and playback devices manufactured by Blackmagic Design.

These nodes provide the ability to list devices, receive video frames from a capture device, send video frames to a playback device, switch input connections, and switch video modes. (Other features, such as VTR controls, are not yet supported.) These nodes do not directly support sending and receiving audio, but since Blackmagic Design provides standard macOS audio drivers, you can use nodes in the Audio node set to work with Blackmagic audio.

Before using a Blackmagic device with Vuo, you need to download and install the Desktop Video software from the Blackmagic Design Support Center.

Supported devices

The following Blackmagic Design product lines are supported:

Only some Blackmagic Design products can simultaneously capture and play back video (“full duplex”). For example, DeckLink and UltraStudio products with “4K” in the name do support simultaneous capture and playback, whereas the Intensity Shuttle Thunderbolt does not.

Device configuration

Some Blackmagic devices support autodetection of the device’s connection and video mode, described below. Others do not, and you have to choose the correct settings in Vuo in order to receive or send video.

Connection

Several nodes have a Connection port, which indicates the physical input source or output destination on the Blackmagic device. For example, if you’re capturing video from a camera plugged into the Blackmagic device’s HDMI IN port, the connection type in Vuo would be HDMI.

Video Mode

Another common port is Video Mode, which indicates the resolution and framerate being used by the Blackmagic device. For example, if you’re capturing video from a camera that’s transmitting HD 1080i at 59.94 fps, that would be the video mode in Vuo. To find out the video modes compatible with your hardware, consult its documentation.

Sub-device

Some Blackmagic devices have multiple inputs or outputs of the same connection type. Nodes such as Specify Blackmagic Input and Get Blackmagic Output Values have a Sub-device port that distinguishes between the same-typed connections on the device. Sub-devices are numbered consecutively starting at 1. Device input editors and the List Blackmagic Devices node list each sub-device as a separate item.

Deinterlacing

If your input source uses an interlaced video mode (NTSC, PAL, or HD 1080i), you may wish to remove the interlacing before applying spatial filters to it, or before displaying it on a progressive video output device such as a computer LCD display, projector, or an HD 1080p display. These nodes offer a few deinterlacing options:
