YUVN is a legacy raw video image format developed by NewTek for the Video Toaster hardware platform on Amiga systems. It stores digitized video frames in a YUV color space, primarily used for broadcast television production and professional non-linear editing. This format follows the Interchange File Format (IFF) structure and is considered safe, though modern users must utilize specialized software to view or convert these historical assets.
