Most newer computers have the ability to play digital video files.
There are a few formats that your browser may support. When a digital video file is available, there will be text under the button that will describe the size of the file and the formats in which it is available. Also note that video files can be rather large. Some video files can stream, which means the file will start playing before the whole file is downloaded. Therefore, a 4 Mb file may start playing after 2-3 minutes while it continues to download.
