S’nerd (super nerd) that I am, I find this workflow to be really exciting. This method allows you to merge jam-synced second-source audio metadata (logged on-set by the sound recordist) with your video footage. If timecode is properly synchronized between sources, you can sync the sound to the picture AND merge the metadata in under 15 minutes. In this tutorial, I’m also making multiclips from the day’s shoot.
3rd party apps used in this vid, which I highly recommend for use with FCP X:
Sound Devices Wave Agent (free)
One app I didn’t use in this workflow that I also recommend is Shot Notes X. It’s a really smart new utility that allows you to merge script notes with your shot footage. We tested using Shot Notes in conjunction with Sync N Link at NAB and, I’m happy to say, they all works brilliantly together.
