Online video and opening titles
Online video does not require an opening title.
On television, opening title is the only way to introduce a program. It alerts the viewers that the program is about to begin, giving them several seconds to make themselves comfortable in front of the TV.
On the Internet, the video is introduced by the content of the page it is on. There is already a title and in most cases even a description. And it’s up to user when to hit “Play”. When she does, there’s no point in alerting her, it just irritates her by delaying the show.
If video is made to be used on many different sites and thus needs some sort of title within itself, it’s always better to use a signature in the corner or on a plate which fades out shortly.
