When a Blackmagic video I/O device was disconnected or lost power temporarily, the affected input and/or output slots will display a ”No Image Source” placeholder image.
If the device did not automatically resume receiving and/or sending the video signals after re-connecting, and still shows the ”No Image Source” placeholder image or a black video image, a Blackmagic background process did not restart successfully.
Follow the steps below to manually restart this background process to continue receiving and sending signals with the device:
- Close the application
- Ensure the device is connected to the machine and has power
- Restart the application
- To restart that process manually, open the Activity Monitor application and search for “blackmagic”
- Select all processes named “com.blackmagic-design.BlackmagiclO.DExt”, press the “X” button in the toolbar, and proceed with “Force Quit”
- The process(es) will be quit but will re-appear immediately
- Shortly after you re-started the process(es), the device should resume receiving and/or sending the video signals in Reeltime Pro as intended
