Shooter suite includes pluraleyes, a stand-alone application that gives you the most accurate a/v sync available for any non-linear editor. Pluraleyes syncs audio and multi-camera video with the touch of a single button, in seconds. And while it works with many nles, pluraleyes can also sync directly in adobe premiere pro, so you never have to leave the app.
This is the complete shooter suite with the keys.
Available for mac and windows.
