Red Giant PluralEyes enables you to sync video footage with externally recorded sound at the press of a button in just seconds, as long as you simultaneously also recorded the sound in-camera. It does this by matching up the waveforms of the external recording to the in-camera recording.

PluralEyes 4 is standalone software, not a plug-in, and therefore imports video and audio data directly from your computer and can export the synced up file to virtually any editing system. It's also capable of importing timeline sequences directly from Premiere Pro and Sony Vegas and then exporting them back out to these editors after you've made your syncs. The application has a feature called the Premiere Pro Panel, which allows you to export to PluralEyes, sync, and then import back into Premiere right from Premiere. The Premiere Pro Panel opens up PluralEyes for you and lets you work from inside Premiere.

During the syncing process, you can watch as your footage and audio are being synced, and color-coded visuals show the status of your footage so you can easily identify any problems that might need some attention on your NLE's timeline.
