Singular Software by Red Giant DualEyes for Mac

Singular Software's DualEyes is a valuable addition to post-production workflows in which video needs to be synchronized with externally recorded audio. This is especially useful when shooting DSLR video, where dual-system setups are increasingly used to capture professional-level audio. Whether you use a slate or timecode (or nothing at all) for reference, DualEyes will compare the external audio track to that recorded by the camera and automatically sync picture to sound. From there, import the synchronized clip into your Windows-based NLE of choice and you're ready to edit!
