Beginning in September, iStock will sell broadcast-quality footage, with a focus on digital formats, including HD video. Thirty-second clips will start at $5. The new video clips will be accessible at iStockVideo.com.“There is a huge demand for video; people want up-to-the-minute, top-quality footage, but current prices are keeping most potential clients out,” said Bruce Livingstone, founder and CEO. “iStock is excited to provide videographers that same immediate connection between artists and global customers, just as we did with stills.”
