HeySummit does not have a separate Gather Voices provider. You can still use a video created in Gather Voices by adding it to a session as pre-recorded content.
Use the option that matches the video you have:
If you published or uploaded the video to a supported video host, select that provider in HeySummit and paste the video URL or ID.
If Gather Voices gives you an embeddable player or gallery code, select Embed Code and paste the full code.
Add the video to a session
Go to Content & Schedule > Sessions.
Open the session's row actions and select Manage Session.
Open the Broadcast step.
Set Broadcast Type to Pre-recorded.
Select the relevant provider or Embed Code.
Paste the video URL, ID, or embed code into the field.
Select Save and Close.
If you use embed code, preview the session before promoting it. Third-party embeds can have their own privacy, playback, or browser restrictions.
