The Horita VS-50 “Video Stopwatch”™ overlays your NTSC or PAL SD analog composite video with an “on-screen” timer display to help you time lectures, speakers, events, talent, rehearsals, indicate time remaining, etc. Plus, with the VS-50 GPI output signal, you can trigger and time sound or other effects, laboratory experiments, etc., relative to the action in your video.
