Multi-angle capture, frame-accurate replay and digital PTZ — native to OBS.
OGRAF overlays that paint live scores, results and sessions on the program.
Every court's clips gathered to one LAN portal — one click, no IT setup.
Four products. One signature.
re-strike.netFrame-accurate instant replay, native to OBS.
A C++ plugin that turns OBS Studio into a courtside replay desk: continuous multi-angle capture, frame-by-frame review, digital zoom and live telestration — armed by the scoring machine and operated from a single dock.
A real captured replay: four armed angles plus the live scoreboard feed, every camera ending on the same trigger frame. Flip between CAM 1–4 and they stay locked to the exact moment.
Real cameras decide real points.
In taekwondo, instant replay is evidence — the referee judges a contested point frame by frame. reStrike shoots every angle on real Sony Alpha cameras with fast prime glass, not the cheap IP cameras that smear the decisive moment into a guess.
Four 1080p60 Alpha angles are stitched into one frame-synced 4K60 multiview — so the four multi-angle feeds share a single clock and every camera ends on the exact same trigger frame.
For replay you don't want cinematic motion blur — you want every frame sharp enough to freeze on the point of contact. That takes a fast shutter speed, and a fast shutter only works when enough light reaches the sensor.
A bright f/2.0 lens on a large APS-C sensor delivers that light even under dim venue strip-lighting — so a spinning head kick lands as a crisp, frozen frame instead of a smear. A tiny IP-camera sensor with a slow lens can't: venue light forces it into a slow shutter (blur) or heavy gain (noise).
The live PSS scoreboard — Daedo or KP&P — is captured as a feed inside the very same 4K60 multiview, locked to the same trigger frame as every camera. No drift between the action and the score: a review shows exactly what the clock and score read at the instant of contact.
▸ When the referee can see foot contact, scoring zone and validity — and the exact score and clock at that frame — the call holds up. Confident decisions, fewer protests.
CAM1–4 + score feed, each with its own decoder, locked to one transport clock and end-aligned to kill inter-camera skew.
Step one frame at a time with the scroll wheel, slow-motion from 0.25×, and an in-RAM ring buffer for lag-free review.
GPU zoom, pan and tilt — drag a region on the program to push in, with no re-encode and no quality loss.
Draw circles, lines and freehand straight onto the replay — rendered into the program output for the broadcast.
Listens to the live Daedo or KP&P system over UDP and turns clock, scores, warnings and results into semantic events.
Records each match, writes crash-safe chapter markers for every scoring moment, and auto-restarts if a match drops.
A rules engine fires scene switches and reStrikeSGX graphics from scoring events, OBS events or a time of day.
Freeze the UI, hide the menus and lock the desk for court-laptop operation — unlock with a passphrase.
A replay engine built for the moment, not the seek bar.
"Instant replay" inside OBS is usually frame-seeking — every step re-decodes from a keyframe and stutters. reStrike ships its own async source and on-demand FFmpeg decoder, so review is smooth from the very first frame.
A stateful decoder walks frames in order with PTS-paced playback and smart rebuffering — no per-frame-seek lag, no stutter scrubbing back and forth.
Optional d3d11va / NVDEC hardware decode keeps 4K replay fluid on a discrete GPU, freeing the CPU for capture and encoding.
A decoded-frame ring buffer around the playhead keeps wheel frame-stepping instant — no re-decode, even scrubbing back and forth.
A ±2-second window around the playhead — 240 fully-decoded frames at 60fps — is held in RAM. Every scroll-wheel step lands instantly with zero decode lag, forward or back, for ultra-smooth frame-by-frame review. It auto-arms the moment you enter the replay scene, so the buffer is primed before the first contested call.
Each match is saved as its own MKV in the session's /matches folder. Every PSS event — round, time, score, technique — is embedded as a chapter with bundled mkvpropedit, so an editor jumps straight to the action.
MATCH - no - blue (NOC) vs red (NOC), ready to archive.reStrike speaks the ATEM protocol directly: your program scene cuts the physical switcher through an editable scene-to-input map. Flip on bidirectional sync and an operator cut on the ATEM flips OBS too — with a 750 ms echo-suppression latch that kills feedback loops. Validated live.
Built to not fail mid-tournament.
Nothing auto-connects when OBS launches and everything disconnects on close — so a stray packet never hijacks your desk. When you're ready, one button reconnects every configured integration, one at a time.
PSS, switcher, OCR, overlay and live feed never auto-bind. One Session-page button brings them all back from saved settings, in sequence.
Bundle settings, log-config and hotkeys to move a configured rig to a new machine — import rewrites user-profile paths automatically.
A fresh machine can import a bundled default OBS profile, scene collection and reStrike settings — courtside-ready in minutes.
reStrike saves and restores its own frontend hotkeys (OBS doesn't), with a one-time "assign defaults?" prompt.
When the PSS UDP path isn't available, a Tesseract reader lifts match # and both athletes straight off the Daedo scoreboard for file naming.
A passphrase gates the session restart, and kiosk mode freezes docks and menus app-wide — so nothing gets bumped mid-session.
reStrikeOBS pushes live match state — court, tournament, scores, clock — straight to re-strike.net/live. Coaches, family and fans follow every court in real time, and any tournament can embed the board on its own site.
Broadcast graphics that paint themselves.
OGRAF web overlays — scoreboards, player banners, gam-jeom, results, winners and full-screen session cards — rendered as a transparent OBS Browser Source and driven live by the scoring feed. The clock ticks, scores update, flags fly, in real time.
Build named GSAP variants — "Punchy", "Subtle" — and bind them per tournament, per court, or override inline from an OBS trigger.
Stream-start, lunch-break and stream-end overlays count down to a real time and remove themselves when it's reached.
Every clip, every court, one link.
One click on each court laptop shares its replay clips on the venue LAN. A hub gathers them all into a single web portal that coaches and officials open in any browser — no IT setup, no accounts.
