Looks like many social websites have finally come to the idea that people love to share videos with each other. So did Flickr, but will it be able to compete YouTube? That is the question.

Last Spring Yahoo has added a video hosting feature to its Flickr, but only for paid users of the Pro version. Recently the company has announced that now even users with free accounts can put their videos on Flickr. The service has also been enhanced with high-definition video quality, still only for members with paid Pro subscriptions.

Free users will be limited to two video uploads per month, and each video is limited to 90 seconds in length and 150MB in file size. This compares pretty scantily with YouTube’s allowance of up to 10 video uploads at a time with a 1GB size limit for free account holders. Vimeo permits 500MB and one HD video upload per week for free users.

A company representative clarified the free account situation as follows: “Anyone (Free and Pro) can upload HD video but it will only be processed as HD video if you are a Pro member. What this means for Free members is that Flickr keeps the original file, so if you ever decide to upgrade to a Pro account, your video will automatically update to HD, too.”

At the same time, YouTube has decided to give it’s users new opportunities: the site is launching a new Adopt A Feature campaign, inviting users to create videos showing off some of its lesser-known features, like AudioSwap. YouTube will track the progress of the features on its blog, and will present the most effective videos on the YouTube homepage and as permanent additions to its help pages.
