Reeltime Pro supports a wide range of video I/O cards by DELTACAST for capturing and playback of SDI signals.
Associate device ports with input and output slots
Within the slot manager, you can associate your Blackmagic device’s SDI input ports with an input slot and, in the same way, SDI output ports with output slots:
- In existing slots, you can choose from all currently available ports in the “Device” drop-down menu.
- If you want to add a new slot, you can press the “+” button that lets you associate a device port with your new slot directly.
You can configure your device’s bi-directional SDI ports by assigning them as an input port or as an output port within the slot manager’s input or output tab. If you configured a bi-directional port as input, it will no longer show up in the drop-down list of available output ports (and vice-versa).
Tip: See DELTACAST’s cabling guide for your SDI card to identify the device ports.
When configuring an input port, there are the following options:
- Format: The video format of the incoming video signal sets the video format of your device automatically.
- Camera Type: Ensure that the appropriate camera type is set to receive the camera’s ANC metadata correctly and trigger recording based on the record flag embedded in the SDI signal.
- Record Trigger: You can choose which detection method should be used to trigger the recording automatically. Note that the appropriate method depends on your setup and camera:
- Choose “Record Flag (HANC)” to detect the record flag embedded in the horizontal ANC metadata of SDI signals from ARRI, RED, and Sony cameras.
- Choose “RecRun Timecode” if your camera is set to use RecRun timecode and you would like to trigger recording/stop recording depending on whether the timecode is running or the timecode is stopped.
- Choose “None” to disable the auto-record function for this camera
- Decoding Levels: In rare cases, you can change the decoding levels from legal to full, for example, if you receive an ungraded signal from a Sony camera that outputs an SDI signal in extended range.

When configuring an output port, you can set an output video format manually. However, it is recommended that the output’s video format be set based on the incoming video format.
Configuring output ports for integer or fractional video formats
You can configure your DELTCAST output ports either for integer or fractional video formats in the “Devices” settings under “DELTACAST Video Output Configuration”:
- Clock System: For your video output configuration, you can choose between
- 1/1 divisor: 24, 25, 30, 50, 60 fps
- 1/1001 divisor: 23.98, 29.97, 59.94 fps
This setting applies globally to all currently connected DELTACAT cards. When you change this setting, you need to restart the application to apply your changes.
