In production — live broadcast deployments

Broadcast replay,
rebuilt for the new century.

A complete multi-channel replay system: frame-accurate slow-motion, instant clips, angles and playlists — driven from a browser or a hardware panel, powered by a GPU-accelerated engine that records everything, all the time.

Capabilities

Everything a replay operator needs.
Nothing standing in the way.

Designed side-by-side with working broadcast operators — every feature exists because a live production demanded it.

🎥

Multi-channel ingest

SDI capture via Blackmagic DeckLink and SRT network feeds. 1080p50 and 1080i50 with GPU deinterlacing. Every channel is one continuous, clock-locked timeline.

🎯

Frame-accurate replay

Intra-only H.264 means every single frame is instantly seekable — scrub, jog, play backwards and ramp speed from 5 % to 100 % without ever losing a frame or audio sync.

🎛️

Hardware & browser control

Full JL Cooper SloMo Elite support — T-bar, jog wheel with FastJog, clip banks, lamps and LCD — mirrored live with a fast browser UI. Several operators can work at once.

✂️

Clips, angles & playlists

Mark in/out on the fly and every camera angle is captured with it. Build playlists with per-entry trims, speeds and transitions — edit them while they play.

🖥️

Multiview with audio

Composited multiview over NDI, RTMP and in the browser — timecode, tally, clip status and audio meters. Continuous monitoring audio, and a TC-search mode where every camera follows your jog wheel.

📤

Instant delivery

Export any clip or a whole playlist as a frame-exact MP4 straight from the browser. SDI, SRT and NDI outputs play out at a rock-steady 50 fps CFR.

📥

Import anything

Drag-and-drop files, professional MXF camera media, or a watched FTP folder — everything is transcoded to the internal format and appears as ready-to-play clips.

⏱️

Timing integration

Connects to live timing systems and cuts finish-line clips automatically at chosen split points — replays are ready before the crowd stops cheering.

🛡️

Built to survive live

Ring-buffer retention with protected clips, session resume after any restart, and a self-healing control plane. The recording never stops — that rule outranks everything else.

Workflow

From live moment to replay in three moves.

The operator experience follows the classic replay workflow you already know — just faster, and everywhere.

Capture everything

All cameras record continuously into a rolling multi-hour buffer. Stop worrying about missing the moment — it is always already recorded, on every angle.

Mark & build

Jog to the action, press IN and OUT, save. The clip exists on every camera angle instantly. Stack clips into playlists, trim entries in place, pick angles per shot.

Replay & deliver

Take it to program with the T-bar at any speed, roll a highlights playlist with transitions, or export the package as MP4 for editorial and social — all frame-exact.

Technology

A modern engine under broadcast discipline.

One native engine owns capture, storage and playout. A web control plane makes it operable from anywhere — including over the public internet.

  • C++20 GPU engine. NVENC encoding and NVDEC decoding end-to-end; one process runs all channels and players.
  • Clock-locked timeline. Every frame number is wall-clock time. Angles switch with zero drift, and multi-camera replays stay in perfect sync — for days.
  • Segmented grow-file storage. Intra-only H.264 in 10-second segments with a binary frame index and sample-exact audio — read while writing, recover after anything.
  • Web control plane. Node.js + React operator and admin UIs, live previews in the browser, shared operator state across surfaces and remote sites.
  • Standard connectivity. SDI (DeckLink), SRT, NDI, RTMP, FTP and file-based workflows — it drops into the truck or gallery you already have.
