Premiere Pro hands its picture to other apps through Mercury Transmit, the route a Blackmagic or AJA card uses. The dfine.io Transmit plug-in registers as one of those devices, and dfine.io Studio sends what it receives to Review or Streaming Classic. You need dfine.io Studio on the Mac that runs Premiere Pro, and a Review room or a Streaming Classic stream.

Play your sequence. In Studio the Adobe Premiere Pro row now shows the size and frame rate, for example 1920×1080 · 25p, instead of Plug-in not connected. Click the row to put it on air, then click Start Streaming. Your client sees the picture a few seconds later.

If the picture arrives behind the sound, raise Video delay in the gear. It holds the picture back by up to 350 ms.

​
When nothing arrives

Premiere Pro was running during the install. Quit it completely and start it again. Mercury Transmit is off. The device checkbox does nothing while the main switch is unticked. Another device claims the output. Untick Blackmagic Playback or NDI output and try again. Nothing is playing. Premiere only sends while it plays or scrubs. On a paused timeline the last frame stays on the stream. More causes: Streaming from dfine.io Studio. Remove plug-in in the gear takes the plug-in out again.
