Overview
SL NEO Instant Replay & Slow Motion is a professional replay and slow-motion platform for sports, live events, broadcast studios, and other real-time production environments. It provides instant access to live and recorded content for frame-accurate replay, variable-speed slow motion, clip creation, and highlight playback without interrupting ongoing recording.
The platform supports single-channel, multi-channel, and synchronized multi-camera workflows, with simultaneous Record, Replay, Program, and Preview outputs. Operators can access any point in the live recording buffer, create clips while recording continues, and control playback speed from 1% to 200% using a software interface or T-bar controller.
As part of the SL NEO Media Platform, Instant Replay & Slow Motion combines recording, replay, graphics, and media handling in a unified workflow, supporting fast turnaround for sports production, studio shows, live events, and highlight creation.
