First, for those I haven't somehow managed to tell yet, I have a couple of courses on sound for video - one on recording and one on post processing. Please have a look at them over at School.LearnLightAndSound.com.
In this week's session, we demonstrate how free-run timecode works. For those not familiar with timecode, this allows you to more efficiently sync your separately recorded video and sound clips before editing your video. It works by syncing up your camera(s) and audio recorder with the help of timecode generator clocks.
In this demonstration, we show how to do this with a Tentacle Sync, a MozeGear TIG Q28, and a Sound Devices 633 recorder. If your recorder does not have a timecode generator built-in, you can still do this by connecting another timecode generator (like the Tentacle or MozeGear) to your recorder.
