#Blackmagic desktop video utility drivers

Cool.īy default the drivers will configure the devices for just only 4 channels to work. The Blackmagic Video Desktop Utility shows Quad 2 as two DeckLink Quad devices, but allows you to work with it as with 8 independent DeckLink devices. The system did not detect the new board until 10.6.1 drivers were installed ( 10.6.2 have become available now, and we tried them too). Blackmagic has pushed the cost per channel to under $125. Just like the original Quad, the new board retails for $995. This means that you can use the board in any combination of inputs and outputs.

Blackmagic states, that each of the 8 connections is completely independent and “can input or output entirely different video standards and content streams, all at the same time”. The Quad 2 supports SDI formats in SD and HD up to 1080p60. Both are PCI Express (PCI-e), but the Quad 2 is wider, so it probably requires more bandwidth - see out tests with expansion systems below. The 9th connection is for the reference signal (genlock). Just like the original Quad, the new board has 9 3G-SDI connections, but here each of the 8 channels is bi-directional (you can configure it for either in our out), whereas the old Quad used 2 connections for each of the channels (one for input, one for output - it wasn’t possible to configure each of the connectors to be in or out). Instead of 4 radiators, there are two coolers that are built into larger radiators - and reasonably: since the board provides twice the processing power on a smaller surface, it needs better cooling. The new board is smaller than the original Quad. Well, finally the new board is in our lab and we can put it through some initial tests. Four years later, at IBC 2015, Blackmagic Design announced Quad 2 - a “capture and playback solution that puts the power of 8 DeckLink cards onto a single circuit board”.

Use the macadam.The original DeckLink Quad was announced in 2011 at NAB as “4 separate DeckLink capture cards” that plug into just one PCIe slot. Not all Blackmagic devices support keying. Keying allows the combination of a provided graphics overlay with a video source, either within the Blackmagic card ( internal keying) or by outputting a key and fill signal on two separate SDI outputs ( external keying). Keying is implemented as an extension of the playback functionality and can be used with both the scheduled and synchronous mode. Once playback if finished, call playback.stop() to release the associated resources. For example, for the third device at index 2:

To find out the current configuration of that device, call the get function with the device index as an argument (defaults to 0). Use getDeviceInfo() to work out the index of the DeckLink device that you would like to configure. Device configurationĭevice configuration can be carried out either by using the Blackmagic Desktop Video Setup utility before running macadam, or by using the getDeviceConfig() and setDeviceConfig() functions. The index of a device in this array is used as the deviceIndex in calls to capture, playback and keying.

Note: For MacOSX Mojave, install the following package after xcode-select -install: This requires a C/C++ development kit and python v2.7.

Install node-gyp and make sure that you have the prerequisites for compiling Javascript native addons for your platform as described.

#Blackmagic desktop video utility software

Install the latest version of the Blackmagic Desktop Video software for your platform, available from.This software has been developed against version 10.11.0 and will track the Node LTS version. Why macadam? Tarmacadam is the black stuff that magically makes roads, so it seemed appropriate as a name for a steampunk-style Blackmagic binding. Please note that Blackmagic USB3 devices are not supported under Linux.

#Blackmagic desktop video utility windows

Linux, Windows and MacOSX are all supported by this release. Keying is supported where it is available on the device. Bindings to link Node.js and the Blackmagic Desktop Video devices, enabling asynchronous capture and playback to and from Blackmagic Design devices via a simple Javascript API.
