Fencing video analysis app
Upload a fencing bout and FencingLab's AI breaks it down action by action — attacks, parries, ripostes and footwork, each with a timestamp — then scores your technique and tells you what to work on. Foil, épée and sabre.
What the video analysis gives you
- Every action, timestamped. Attacks, parries, ripostes, counter-attacks and footwork are detected and listed with the moment they happen, so you can jump straight to them in the video.
- Technique scores. Accuracy, Speed, Technique and Tactics, each scored from 0 to 100 — for you and for your opponent.
- Coaching insights and drills. Strengths, weaknesses and specific, actionable drills based on what happened in the bout.
- Weapon-aware. The analysis adapts to foil, épée or sabre — right-of-way, target area and typical tactics differ, and so does the feedback.
How fencing video analysis works
- 1. Add a video. Upload a bout from your computer at fencinglab.app, or record and import it in the iPhone app. Training bouts, drills and competition videos all work.
- 2. Choose the analysis. Local AI runs on FencingLab's own servers; every account includes 5 Local AI analyses a month (unlimited with a subscription). Cloud AI uses credits: immediate results in under a minute, or batch overnight at half the cost. You can also analyze just the segments you select on the timeline.
- 3. Review and improve. Read the action breakdown, scores and drills, compare with previous bouts, and share the video privately with a teammate or coach.
Tips for a video that analyzes well
- Film from the side of the piste, roughly level with the middle of the strip, so both fencers stay in frame.
- Keep the phone steady (a tripod or a fence post helps) and avoid zooming in and out during the bout.
- Make sure both fencers are clearly visible — telling the AI which side you're on and a distinguishing detail (for example "red socks") helps it follow the right fencer.
Track progress across bouts
Every analysis feeds your profile: score history charts, technique usage with success rates, and comparisons against your own baseline — so you can see whether the work you're doing between bouts is paying off.
