WASHINGTON, USA - Video-sharing site YouTube announced on Wednesday that it was doubling the size limit for uploads to its website to allow users to post more high-definition (HD) video.

YouTube, in a blog post, said the size limit for uploads to the site was being doubled - from one gigabyte to two gigabytes.

"The increase means you can upload longer videos at a higher resolution as well as large HD files directly from your camera," YouTube said.

"The changes allow you to share links directly to the HD version of your video, as well as embed the HD version on your blog or website," it said.

HD video is increasingly popular but the higher resolution results in larger files.

A YouTube spokesman told AFP that while file size for individual videos was being increased to two gigabytes, the 10-minute length restriction for videos posted on the site remains in place.
