YouTube Works to improve Image Quality

While YouTube.com has garnered millions of users around the world, not everyone has been thrilled about the picture quality. Sometimes it's grainy, or dark, or blurry. Some advertisers have shied away. And some film-makers have protested.

But the quality is changing. Quietly this week, the company began experimenting - on more than a thousand videos - with much higher quality video streams. Company officials said they expect to soon broaden the move.

On the improved videos, users may press a button to "Watch this video in higher quality." If the user's Internet connection is a good one, what comes across is two to three times as many bits per second - and a sharper, clearer picture.
