Livestream Studio - What stream quality will my viewers receive?
When you stream to our servers, we'll create various qualities of stream available, as high as 4K, depending on your source.
The attendees will watch the highest quality suitable for their internet connection.
You should be aware of a typical 5-15 second latency from your live feed to the end viewer.
