Discussion Browsers render the video player according to the dimensions you assign， not the resolution of your actual video. Using different dimensions might lead to a loss in quality by expanding a video beyond its native resolution; the same goes for scaling down a large video simply to fit into a small space.
So， when possible， use the same dimension values for the video element as for the vide of ile itself， and don't resize your video with width and height. Technically speaking， the width and height of a video element do not need to be set as browsers default to inheriting the dimensions of the video file itself. The drawback to this approach is that if the dimensions are not set， browsers won't know what space to reserve for your video and may have to redraw your page after downloading the videodata， The width and height values need to be set in CSS pixels as integers and not aspercentages or other values. Adding dimension values helps browsers more efficiendyrender your pages， which usually results in a better user experience. Since you probably don't want to use width and height to resize your video to something other than its native dimensions， you can instead use encoding software to specify ther esolution.
