Once Sport Analyser — Complete Guide to Video Analysis, 3D Telestration, and Live Analysis

What Is Once Sport Analyser?

Once Sport Analyser is a professional sports video analysis platform combining advanced match tagging, broadcast-quality 3D animated telestration, automatic AI player tracking, and live match analysis in a single application — used by coaches and analysts at all levels, from elite professional clubs to amateur academies, across more than 100 countries.

Developed by Once Sport (Austria), the platform is built around one core positioning: the best quality-to-price ratio in professional sports video analysis. Where platforms like Hudl Sportscode or Nacsport target primarily the professional tier with corresponding price tags, Once Sport aims to make elite-level analysis tools accessible to the full coaching community — semi-professional clubs, academies, individual analysts, and grassroots teams who need professional output without enterprise pricing.

The Once Sport product ecosystem includes four tools:

Once Sport Analyser — the complete video analysis suite (this guide’s focus)
Once Sport Telestrator — drawing and telestration only, without tagging or live analysis
Once Sport Coach Board — tactical board and session design (included with all Analyser plans)
Once Sport Autocam — AI-powered automated match recording from panorama footage

Who uses Once Sport Analyser:

Video analysts and performance analysts at professional and semi-professional clubs
Head coaches who conduct their own video analysis
Academy and youth development coaches
National team analysis departments
Independent analysts building client-facing analysis businesses
Journalists and content creators producing tactical breakdowns
Coaching certification candidates building analysis portfolios

Notable users: GNK Dinamo Zagreb, Paris FC Women’s Training Center, SV Sandhausen, and clubs and federations across Europe, South America, and beyond.

Free trial: 14 days, no credit card required.

The Once Sport Philosophy: Professional Analysis for Everyone

The defining tension in sports video analysis software is between professional-grade features and professional-grade prices. Most platforms with elite tracking and telestration capabilities carry price points that exclude all but funded professional clubs. Once Sport’s explicit positioning challenges this:

No hidden costs — your subscription covers all features in your tier, no per-feature add-ons
No storage limits — unlimited analysis projects
Works offline — most features function without internet
Unlimited sharing — export and distribute your analysis without per-export fees
24/7 support in 7 languages — customer service that typically responds quickly regardless of timezone

This makes Once Sport particularly compelling for the large middle tier of sports organizations — clubs at the 2nd or 3rd tier of national leagues, ambitious youth academies, smaller national federations — that need professional output but cannot justify enterprise licensing costs.

Core Features in Detail

1. Advanced Tagging System

Tagging — categorizing and timestamping match events as you review footage — is the foundation of systematic video analysis. Once Sport’s tagging system is designed for both retrospective review and live match use.

Code buttons: Create custom code buttons mapped to any event category your methodology uses: shots, pressings, transitions, individual errors, set pieces, defensive organization events, transition opportunities — anything relevant to your analysis framework.

Two tagging modes:

Regular code buttons: Click the button when you spot the event. Once Sport automatically captures the configurable window (1–20 seconds) before and after the click — so if you click on a pressing trigger, you automatically get the 10 seconds before and 10 seconds after the event without manual trimming.

Recording mode code buttons: Click to start recording an event, click again to stop. The system captures exactly the duration of the event. Useful for possession sequences, pressing phases, or any event with variable duration.

Keyboard shortcuts (hotkeys): Assign keyboard shortcuts to any code button for rapid tagging without looking away from the video. Critical for live analysis speed.

Action metadata:

Mark tagged events as Good, Bad, or Favourite for quick filtering
Add player attribution — tag which specific player(s) are involved in each event
Add free-text notes to individual tagged actions
Replace incorrectly attributed players without re-tagging the entire action

Timeline view: The timeline shows all tagged events in chronological order with their code categories. Filter by code type, player, rating (good/bad/favourite), or any combination. Navigate directly to any tagged moment.

Playlist management: Organize tagged clips into structured playlists — for example, “Opponent pressing triggers” or “Our defensive transitions — errors.” Sort and reorder clips. Export the entire playlist as a single video with or without drawings.

2. 3D Telestration — Broadcast-Quality Animated Graphics

Telestration — adding visual graphic overlays to video — is where coaches transform raw footage into communication tools. Once Sport’s 3D drawing engine produces the kind of animated graphics you see in broadcast football analysis.

Drawing elements available:

Movement indicators:

Arrows — straight, curved, or dashed; animated to show direction of movement
Dashed arrows — conventional notation for off-ball runs and anticipated movements
Movement paths — multi-point trajectory lines following a player’s actual movement

Zone and area tools:

Player formation area — filled polygon between players to show shape and compactness
Highlighted area — zone marker for pressing traps, dangerous spaces, or tactical zones
Circle/spotlight — focus attention on a specific player or area

Tracking and annotation:

Player spotlight — circular highlight that follows a tracked player
Players Formation Line — straight line connecting multiple tracked players (defensive/offensive line)
Text overlays — static text and dynamic overlay (text that appears continuously without pausing video)
Custom freehand drawing — draw any shape not covered by preset tools

Visual effects:

Chromakey — place graphic elements behind players for a natural, integrated look rather than floating overlays
Zoom — zoom into specific elements within a frame for close-up emphasis

3D perspective: All drawn elements are rendered in 3D perspective matched to the camera angle of your footage — arrows, zones, and lines look like they exist on the pitch rather than floating as flat 2D overlays.

Animation: Graphics animate smoothly during video playback. An arrow showing a player’s run follows the path as the video plays; a defensive line moves with the defensive shape. This is the feature that produces the broadcast-TV look.

3. Automatic Player Tracking

Once Sport’s tracking engine uses AI keyframing technology — the system automatically calculates intermediate frames between manually set or AI-detected keyframes, producing smooth, natural-looking tracking without frame-by-frame manual adjustment.

Tracking workflow:

Select a tracking tool from the toolbar
Click on the player you want to track (or select multiple players)
Once Sport automatically detects and follows the player through the clip
If tracking drifts, pause and reposition — the AI recalculates from that correction point

Extend tracking: Click the “extend tracking” button to add 10 more seconds to an existing tracking trajectory without repeating the setup.

Tracking tools by plan:

Tool	Basic	Pro	Elite
Spotlight (circular highlight following player)	✅	✅	✅
Players Formation Line (line through tracked players)	❌	✅	✅
Full automatic tracking suite	❌	❌	✅

Multiple simultaneous tracking: Track multiple players at once — each with their own graphic element. Track all defenders to show the defensive line, or track the striker and the closest defender simultaneously to show space management.

4. Field Mapping — Distance Measurement on Pitch

Field Mapping (released late 2025) brings real-world distance measurement directly onto match video:

How it works:

Calibrate the pitch — match reference points in the video to known pitch dimensions
Set actual pitch dimensions (standard football: width 68m, length 100–105m)
Once Sport calculates the perspective transformation
All tracking tools display real-world distances in meters automatically

What you can measure:

Distance between players (e.g., gap between defensive line and midfield)
Passing distances (length of passes in meters)
Space covered by a player in a defined sequence
Compactness measurements (how far apart defensive lines are)
Distance from specific players to the ball or goal

Use cases:

Quantifying defensive compactness (e.g., “the defensive block was covering 22 meters horizontally”)
Measuring pressing triggers (at what distance does the press activate?)
Showing passing length distributions across a match
Player positioning analysis with actual spatial data

Important: Field Mapping currently works for football/soccer. Support for additional sports is in development.

5. Live Analysis

Once Sport Analyser supports full live analysis workflows — tagging, drawing, and presenting during actual matches, not just retrospectively:

Live analysis setup: Connect a video source:

Camera with capture card — any camera connected via HDMI capture card
RTSP stream — IP cameras or existing streaming infrastructure
M3U8 stream — broadcast-compatible HTTP live streaming format

During live analysis:

Tag events in real time as they happen using keyboard shortcuts or code buttons
Rewind footage to review and tag events you missed during the action (without losing the live feed)
Draw on tagged clips — quickly add telestration to key moments while the match continues
Export clips during the match without interrupting live analysis
Once Sport automatically records and saves the entire match simultaneously

Halftime presentation: Retrieve all tagged clips from the first half, add quick telestration to the 2–3 most important moments (takes 2–3 minutes with Once Sport’s workflow), and present directly from the application on a laptop, tablet connected to a TV, or projector.

Live streaming (Elite only): Stream your live analysis directly to YouTube Live, Twitch, or any RTMP-compatible platform. Teams can use this for remote coaching staff viewing sessions, public tactical broadcasts, or internal team monitoring across different training groups.

6. Export and Sharing

Video export:

Export individual tagged clips or entire playlists as MP4 video files
With or without drawings — choose whether to include your telestration overlays
Multiple clips can be merged into a single export video or kept as individual files in a folder
Export in different folder organization options (by code category, by match, chronological)

Image export:

Export individual frames with drawings as high-quality images (PNG/JPG)
Useful for report generation, social media posts, printed playbooks

XML export:

Export your tagging data as XML for integration with other analysis platforms or club data systems

Sharing:

Share XML files with other Once Sport Analyser users — they import your full tagging structure
Share video exports via any standard file transfer method (cloud storage, USB, email for small files)
No per-export fees or sharing limits

7. Once Sport Coach Board — Included

All Once Sport Analyser plans include Coach Board — a tactical board and session design tool comparable to TacticalPad, built directly into the Once Sport ecosystem:

Coach Board features:

Animated 3D tactical board with sport-specific pitch templates
Draw player movements, passing sequences, pressing patterns
Design training drills with equipment markers
Plan full training sessions with multiple exercises
Export tactical boards as video or image
Works offline

Sports supported: Football, basketball, handball, rugby, hockey, futsal, and more.

The inclusion of Coach Board eliminates the need for a separate tactical board application — the complete workflow from tactical design (Coach Board) through match video analysis (Analyser) exists within the Once Sport platform.

8. Once Sport Autocam

Autocam is Once Sport’s AI-powered automated match recording tool — a separate product that integrates into the broader Once Sport workflow:

What Autocam does:

Takes panorama video (wide-angle footage covering the entire pitch, filmed without a camera operator)
Applies neural network and computer vision processing
Outputs a video that looks like it was filmed by a professional camera operator — with dynamic panning, zooming, and following of the action

Practical value: Many clubs at the amateur to semi-professional level have a static panorama camera (or can set one up cheaply) but cannot afford a dedicated camera operator at every match. Autocam converts the static panorama footage into watchable, camera-operator-style broadcast footage automatically — ready for analysis in Once Sport Analyser.

Once Sport Video Analyst Certification

A feature unique among analysis platforms: Once Sport offers a video analyst certification program — a structured curriculum that teaches video analysis methodology alongside the software:

What the certification covers:

Video analysis fundamentals and methodology
Using Once Sport Analyser effectively across all features
Workflow design for different analysis contexts (match preparation, opposition analysis, player development)
Creating professional analysis outputs

Practical value:

Verifiable credential for analysts building their professional profiles
Structured learning path for coaches learning video analysis for the first time
Used by players, coaches, and analysts seeking to formalize their analysis skills

This fills a genuine gap — most software only provides technical tutorials. The certification addresses the methodological question: not just how to use the tool, but how to build effective analysis workflows.

Practical Workflows

Post-Match Opposition Analysis

Import next opponent’s last 3 matches into Once Sport
Create a code structure: pressing triggers, defensive line shape, set piece routines, transitional patterns
Tag all relevant events across the three matches (Once Sport’s efficient tagging takes ~45 min per match)
Filter by code category — review all pressing triggers consecutively
For the 8 most important clips, add 3D telestration showing the pattern (arrows, player highlights, zone markers)
Organize into a themed playlist: “Opponent pressing triggers,” “Opposition set pieces — defensive,” etc.
Export as a single video playlist for the coaching briefing session

Individual Player Development Review

Import 5 matches involving the target player
Tag all the player’s defensive actions, pressing contributions, and positional moments
Add player spotlight tracking so the player is always visually highlighted
Use Field Mapping to measure their press activation distance and defensive positioning distance
Export a 10-minute compilation with telestration and tracking
Share with the player for individual feedback session

Halftime Live Analysis

Live analysis is running — analyst has tagged pressing losses and set piece defending in first half
Half time: pull up the 3 most critical clips
Add quick telestration on each — 1–2 minutes per clip maximum
Connect laptop to the dressing room TV (or share screen)
Present 3 clips with coaching points attached — under 5 minutes total
All tagged clips automatically saved for full post-match analysis later

Frequently Asked Questions

Does Once Sport Analyser work on Mac and Windows? Yes — Once Sport Analyser is available for Windows and macOS. Mobile apps are not currently available (unlike TacticalPad which has iOS/Android versions), though Coach Board has some mobile accessibility.

Can I import footage from any camera? Yes. Once Sport imports standard video files (MP4, MOV, AVI, and other common formats) directly from your hard drive without uploading to a cloud server. No special camera hardware is required.

Is Once Sport Analyser completely offline? Most features work offline. Live analysis via stream requires a network connection to receive the stream, and live streaming to YouTube/Twitch requires internet. All local video analysis, tagging, drawing, and export works without internet.

Does Field Mapping work for all sports? Currently Field Mapping is implemented for football/soccer. Once Sport has stated that more sports are under development. All other telestration and tracking features work across all supported sports.

Can multiple analysts share and import each other’s analysis? Yes. Once Sport uses XML file export/import for sharing analysis projects between users. Send the XML file and the recipient imports the full tagging structure into their Once Sport installation. Video files need to be shared separately.

What is the difference between Once Sport Analyser and Once Sport Telestrator? Once Sport Telestrator contains all the drawing and telestration tools (same as Analyser) but without the tagging system and without live analysis capability. It is designed for analysts whose primary need is creating high-quality annotated video clips without the full tagging workflow — for example, a coach who receives pre-tagged clips from an analyst and only needs to draw on them.

Summary

Once Sport Analyser delivers a genuinely complete professional video analysis toolkit — advanced tagging, broadcast-quality 3D telestration, automatic AI player tracking, live match analysis with optional streaming, Field Mapping distance measurement, an integrated Coach Board, and Autocam compatibility — at price points designed to serve the full spectrum of the coaching community rather than only the elite professional tier. Its 14-day full-feature trial (no credit card), offline capability, no storage limits, and 24/7 multilingual support reinforce the accessibility positioning.

For clubs and analysts sitting between the “basic video cutting” tier and the full enterprise analysis budget, Once Sport Analyser Elite represents the strongest value proposition currently available in sports video analysis — with a feature set that genuinely competes with tools costing significantly more per month.
