Video files require significant bandwidth and specific server optimization to provide a reliable, quality viewing experience. The server on which People Page sites are hosted is not designed to handle this significant load. It is suggested that site owners leverage tools that are built for video streaming (e.g. Kaltura, YouTube, Vimeo, etc.) for their video content needs.
Examples of video files include (but are not limited to): AVI, MOV, MP4, WMV, MKV, etc.
