AStream can show up to 3 presenters on the bottom bar of our Web-Based Event Viewer.
With each presenter, you can define a few items including, Type (Host), Name, Title, and a short bio (if using a Bio do keep it short as shown in our example, it tends to detract a lot from the video when too much information is present). You can also select a 'Headshot' photo to use.
Once defining and clicking 'Add' you'll see it populated in your timeline settings.
Below is a view of the AStream platform with 3 presenters defined.
