What is karting analysis?
Karting analysis is going back through a session's lap times, sector splits, racing line and speed traces to find where the time went. Race Ninja does it from the GoPro or DJI footage you've already shot, so every number sits next to the moment on film that caused it.
How it works
Film your session
GoPro with GPS on, or a DJI with its GPS remote. Mount it where you always do.
Upload the footage
Straight from the browser or the Windows uploader between sessions at the track. Optional: add a logger file if you ran one.
Read the session
Laps, sectors, lines and coaching come back together, each tied to the moment on film.
Built for karting, not adapted to it
Sector-by-sector honesty
A kart lap is short. Whole-lap times hide where you're slow. Sector splits show you the corner that's costing two tenths every lap.
Racing line on a real map
See your line through every corner, with braking points marked, and compare your quick lap against your average one.
Coaching a driver can use
Notes in plain language, pointed at the spot in your video. Not a spreadsheet you need help decoding.
Camera first, dash welcome
The helmet or pod camera is enough to start. If you already run a dashboard logger, bring its RPM and temps into the same analysis so the footage gets richer, not replaced.
Three ways to analyse a karting session
They answer different questions, and plenty of club drivers end up using two of them. Here's what each one's good at.
| Logger software | Phone lap-timer app | Camera footage (Race Ninja) | |
|---|---|---|---|
| What you need | A dash such as a MyChron or Alfano, plus its software | A phone in the kart and an app such as RaceChrono or Harry's LapTimer | A GoPro Hero 9, 10, 11 or 13, or a DJI Action 4, 5, 6 or Osmo 360 with the GPS Remote |
| Best at | Engine work: RPM and temperatures, live on the wheel | Cheap lap times | Lap times, sector splits, racing line and coaching, each tied to the video |
| GPS detail | Depends on the dash | About one fix a second from a phone's built-in GPS, roughly 25 m apart at 90 km/h | About ten fixes a second on a GoPro, roughly 2.5 m apart at 90 km/h |
| Where it falls short | You match a chart to your memory of the lap | Too coarse to place a braking point cleanly | No RPM or temperatures unless you import an Alfano or AiM file |
| Works with Race Ninja? | Yes: MyChron + Race Ninja together, Alfano + Race Ninja together | A RaceChrono file can be added at upload | It's Race Ninja |
Run a dash already? Keep it. The camera adds the film and the lines, and the dash file brings the engine channels along for the same lap.
Where two tenths went: one lap at Whilton Mill
B. Philpot's session at Whilton Mill on 19 April 2026 is public, 15 laps timed from onboard GPS video. The best was lap 10, a 0:55.471. Lap 9 is the interesting one.
Lap 9 had the quickest first sector of the whole session, 9.596. It had the quickest fourth sector too. And it still finished 0:55.709, 0.238 s down on lap 10.
A timing sheet would show you 0:55.709 and nothing else. Split by sector, it reads like this:
| Sector | Lap 9 | Lap 10 (best) | Lap 9 vs lap 10 |
|---|---|---|---|
| S1 | 9.596 | 9.670 | 0.074 quicker |
| S2 | 11.566 | 11.382 | 0.184 slower |
| S3 | 12.133 | 12.009 | 0.124 slower |
| S4 | 11.120 | 11.216 | 0.096 quicker |
| S5 | 11.294 | 11.194 | 0.100 slower |
| Lap | 0:55.709 | 0:55.471 | 0.238 slower |
Nearly two tenths went in sector 2 alone. That's the bit worth watching back, not the whole lap. Lap 9 proves the pace for S1 and S4 is there, so the next session's job is narrower than "go faster": drive sector 2 the way lap 10 did and keep the rest.

Common questions about kart data analysis
What is the best app for kart racing data analysis?
Depends what question you're asking. MyChron or Alfano software is right for engine and live dash channels. Race Ninja is right for lap times, sector splits, racing lines and coaching from the onboard footage, with analysis packs that put the proof on film. Best answer for a lot of club drivers is both, not one or the other.
How do I analyse my karting video?
Upload it. If your camera recorded GPS, Race Ninja splits the session into laps, times every sector, draws your racing line and writes coaching notes against the exact moments on film. You watch the lap and read what cost you time at the same time.
Do I need a data logger like MyChron or Alfano?
Not for the camera path. A GoPro with GPS on (or DJI with the remote) is enough for lap and sector analysis. Those dashes are still excellent for live RPM, temps and in-kart timing. Keep them. If you run Alfano or AiM, import the session file so engine data enriches the same video debrief.
Does it work for club racing and owner-drivers, not just pros?
That's exactly who it's for. Club racers, cadets and parents, owner-drivers testing on a Saturday. If the footage has GPS in it, you get a serious analysis pack without a data engineer in the awning.
Can I compare myself against other drivers?
Yes. Leaderboards show verified lap times from real footage at your circuit, so you can see where you stand in your class. Every time on the board comes from onboard video, not typed in by hand.
