The Ambient NanoLockit Miniature Timecode Synchronizer with Logging Feature in a pack of two is a small and easy-to-use timecode logging system that supports all frame rates of timecode in and out. It can be used to easily mark shots using timecode, speeding up your post-production process. Mark each shot as good or no good, and a green or red LED illuminates to confirm your selection. Generate timecode that stays accurate to within one frame over 24 hours, or use an optional C-Jam master to maintain zero drift over the ACN network.
