Do all the versions look like the preview?
The preview video is a proxy of the actual video. While we do our best to represent the file accurately, it compressed with Adobe Flash, and may look slightly lighter, darker, or more (or less) pixilated than the files offered for download. They should be used to evaluate the content rather than the technical quality. It accurately shows the flow and composition of the video. iStockvideo inspects each and every video, and rejects clips that do not meet our technical or content standards.
