How can I ensure my videos will show high-quality?
The PWRU video player plays back video leveraging adaptive streaming – so the best quality video is played back based on the User’s connection, and it will dynamically change and adapt to the User’s bandwidth automatically, should their bandwidth change or become erratic during the playback of a video. On desktop, Users can override the automated quality detection and set the playback quality themselves by clicking the ‘gear’ icon from within the video player controls on the lower right.
Note: Safari used on Desktop and mobile devices do not allow for a way to change the quality manually, and handles all quality switching automatically.
What type of video player do we use?
It isn’t any “type” of video player – it is our “Custom VT Player” which uses industry standard elements with a lot of customization specific to our System.
