TelVue Cloudcast supports any bit rate you want to use. Trends for target bit rates across the internet are changing, both because more bandwidth is available, and because viewers are now using more devices connected to large screens, such as the Roku set-top box. To reach computer desktops or embedded players in web pages, 256 kilobits per second to 512 kilobits per second still generates very good looking video, particularly in the very efficient H.264 format. However, to create full-screen standard definition video for a large (40 inches or more) screen, a higher rate is recommended: 768 kilobits or greater. For 720p or larger HD video, rates of 1200 kilobits or higher are common. You can also control which aspect ratio (4:3 or 16:9) is used for either SD or HD content. The new TelVue CloudCast player automatically supports and sizes 4:3 and 16:9 content.
