Setting up NDI input

This article covers features which are only available in Reeltime Pro

Reeltime Pro supports receiving available NDI input streams in your network via input slots, e.g., for monitoring your Final Cut Pro timeline’s A/V output and distributing the editing preview to the video village.

Install NDI Tools for Mac and create a stream#

  • Install the latest version of NDI Tools for Mac
  • Create an NDI stream with a third-party application such as Final Cut Pro
    • In Final Cut Pro: Go to Settings > Playback > A/V Output and choose the desired NDI output format, e.g., “NDI 1920 x 1080 @24”.
  • If NDI output does not appear in Final Cut Pro’s “A/V Output” settings, you may need to restore legacy video device support within the macOS Recovery Mode:
    • Shut down your Mac
    • Press and hold the power button until the options appear, then
      • continue with “Options” and log in
    • Open Terminal from the utilities menu
    • Enter the command: system-override legacy-camera-plugins-without-sw-camera-indication=on
    • If the returned message is “command not found”, you first have to
      • disable System Integrity Protection (SIP). That is also only possible within the macOS Recovery Mode:
      • If necessary, restart your Mac and enter Recovery Mode as described above
      • Open Terminal from the utilities menu
      • Enter the command: csrutil disable
      • Repeat the steps above to restore legacy device support
      • Remember to re-enable SIP after you have completed the necessary changes: csrutil enable
Note: The Final Cut Pro NDI plugin currently requires SIP (System Integrity Protection) to be disabled when used with newer versions of NDI Tools and macOS. We are in contact with NDI about this.If you prefer not to disable SIP, we recommend using an SDI-based setup, with an SDI output from Final Cut Pro and an SDI input into Reeltime.

Associate an NDI stream with an input slot#

  1. Create a dedicated input slot for receiving the NDI stream, e.g., the A/V output from Final Cut Pro.
  2. Associate the input slot with the NDI input stream; for example, Final Cut Pro’s A/V output stream typically includes the postfix “(macOS A/V Output)”.
  3. To receive audio embedded in the NDI stream, enable the channels of the “NDI Audio” input device in Settings> Audio > Input Devices.
