About MotionStim
Synchronized motion. Local playback. Full control.
MotionStim is a web-based platform for adult film enthusiasts who want synchronized physical interaction with their media. It connects compatible remote-controlled toys to video playback using motion subtitle files, creating a tightly aligned experience between on-screen action and physical response.
Motion Subtitles
Motion subtitles are data files that describe movement over time within a video. These files allow the platform to control supported devices in sync with playback. Common formats include Funscript and TCode.
Motion files can be obtained from:
Supported Devices
