HeySummit does not have a separate native Gather Voices provider. You can still use video created in Gather Voices by adding it to a talk as a pre-recorded video.
Use whichever option matches the video you have:
If you published or uploaded the video to a supported video host, choose that host in HeySummit and paste the video URL or ID.
If Gather Voices gives you an embeddable player or gallery code, choose Embed Code and paste the full embed code.
Add the video to a talk
From your dashboard, go to Content > Talks.
Open the ... menu for the talk you want to update, then choose Manage Talk.
When asked how you would like to broadcast the talk, choose Pre-Recorded.
Select the relevant video provider, or choose Embed Code.
Paste the video URL, video ID, or embed code into the field.
Click Save.
If you use embed code, preview the talk before promoting it to attendees. Some third-party embeds can have their own privacy, playback, or browser restrictions.
