Blackmagic Design Desktop Video is the driver that is required in order for Livestream Producer and Livestream Studio software to recognize video inputs coming in through a Blackmagic Design capture device. If you are having an issue seeing your camera source, it could be an issue with the current version of the drivers you have installed.
If you currently have another version, you should first uninstall that version and then install the recommended Desktop Video version.
At this time, we recommend that Livestream customers download Desktop Video version 10.9.7.
Below on the left side is a column called Latest Downloads. Find the desired version of Desktop Video, and select the operating system you are using (Mac or Windows).
You will be prompted to register. This step is optional. You may skip it by clicking 'Download Only' in the bottom left corner.
When the download is complete, open the .zip folder and run the installer.
Follow the on-screen steps, then restart your computer to complete the installation.
