Interesting plugin. It looks like an audio only app and don't think it will allign the video w/ audio. I watched the demo and don't think it can align multiple tracks w/ video. It syncs audio tracks to a master audio track individually.

As far as what it can do w/ syncronizing audio only for backing audio tracks or voice overs it appearls to be better at doing that than Plural Eyes.

Vocalign also is a VST plugin that can work with other DAW unlike Plural Eyes which only works as a plugin w/ Vegas Pro.

Personally I could use it but $350 on sale is still a bit too much. They do have a $149 version but you are castrated to only 120 seconds = 2minutes of audio. Btw, the Vocalign Pro 4 version allow a whole 300s = 5 minutes of audio. For me, these time limits on audio files are showstoppers.

Product comparison between VocALign Project 3, VocALign Pro 4 & Revoice Pro 3:

Imho, If you have a bunch of audio/video files from different sources that needs to be synched, it would be time consuming using this plugin.
