Sonar provided limited facilities for video, surround sound (5. 1, 7. 1), and supported . avi, . mpeg, . wmv and . mov files. Sonar had the ability to show video as thumbnails contained in a separate track. With appropriate hardware, it was also possible to output the video to an external monitor screen via Firewire. Common SMPTE formats, frame sizes and frame rates were supported. It was possible to transfer audio loop files from other compatible software into Sonar and complete a final mixdown.
