Multitrack Audio Playback

Vor itself does not playback the video it creates, allowing the file to be viewable by any member of the team without downloading additional software. We’ve found it useful to record multiple tracks of audio and route them to different devices, allowing video playback to control your system regardless of your video player. This guide will show you how to route two audio tracks to a MacBook Pro’s internal speakers, and one audio track to the 3.5mm headphone jack. We can use an XLR to 3.5mm adaptor to plug into an ETC Response SMPTE Gateway, allowing your video to playback a SMPTE track, without hearing it.

Required Items

• Computer running macOS

• QuickTime Player
