Yahoo has added support for video to its photo-sharing site Flickr.

Yahoo wants users to start sharing videos, shot by still cameras, camcorders and camera phones, as well as photos, and Video on Flickr provides an easy solution for consumers, according to the company.

Video can be up to 90 seconds long, and no more than 150M bytes in size. To upload video you have to be a Flickr Pro user, but everyone can watch.

Users can upload videos directly from mobile phones, and integrate videos and photos into a stream.

There is also an API for third-party developers to create programs or services using authorized video submitted to Flickr.

Whether it will be able to compete with Youtube remains to be seen, but Yahoo thinks there is a huge untapped market of which it can take advantage.

More than 40 percent of consumers between 18 and 44 are capturing personal video clips with their digital cameras, but they are not taking advantage of Web sites to effectively share their videos.

Fifty-five percent of respondents to a survey commissioned by Yahoo said they merely play back video clips for their friends on their camera device or PC, and 20 percent don't share these clips at all.
