Creator Audio and Video
Streams can be set up as audio only or with video. Streams set up as audio only will replace the video screen with the uploaded thumbnail.
We capture video up to 1280x720 HD Video depending on the creator's bandwidth/client device. 1280x720 is the default selected, and we always attempt to stream at that resolution. If the client device or network conditions do not support 1280x720, we will automatically select the next largest resolution (640x480). Finally, if needed then we will fall back to 320x240.
A creator has the option to pull in video in 2 ways: Easy (in the browser) or Advanced (via RTMP input (OBS)).
The creator video can have from 1 to 6 participants directly from within the browser.
When creating a video you can select a camera to show your audio and video inputs from a dropdown
When a host changes the volume on the stream, it will adjust the volume in the stream, so your viewers can hear more of you, or more of your topic video, depending on how you adjust things.
While HotMic has a production studio that works right in your browser, we also support inputs from other video streaming software such as OBS.
When you select Advanced Mode, you can copy the stream key and server for that stream, and use this to push RTMP from any streaming tool that supports RTMP output.
Note: The stream key and server frequently rotate for security reasons. If you leave the stream and come back after a long period of time, double check the server and stream key.
