Tentacle Sync Micro-USB Timecode Cable Right Angle 3.5mm TRS for Sony FX3 FX30 A7S3 A1 Tentacle ORIGINAL/SYNC E/TRACK E/TIMEBAR. Purchased to connect a DEITY TC-1 to a SONY FX30 and input timecode. Unused. Please refrain from purchasing if you are sensitive to used items. 1. Overview The Tentacle Sync Micro-USB Timecode Cable is a dedicated cable for synchronizing some Sony mirrorless cameras and cinema cameras by inputting timecode signals from external timecode generators, etc. 2. Main Functions and Uses The main purpose of this cable is timecode synchronization. Why is it necessary? When shooting with multiple cameras (shooting simultaneously with multiple cameras), if the recording start/stop timing of each camera is different, the editing work (post-production) to match the video and audio later becomes very difficult. How to solve it? Use a timecode generator (a dedicated device that generates a time signal) as the "master" and use this cable to feed the same timecode to each camera. This allows all cameras to record on the same time axis, making it possible to synchronize video and audio instantly on editing software.
