What you can do, free
Everything you need for a quick side-by-side comparison:
- Side-by-side comparison — Load two onboard videos and watch them play together on one screen. See the differences in racing line, body position, and corner approach at a glance — no editing software needed.
- Independent video positioning — Click either panel to make it active, then scrub, seek, or frame-step that video independently. Find the same reference point on both videos before you start comparing — even if one recording started minutes before the other.
- Per-video scrub bars — Each video has its own mini timeline. Click anywhere to jump to that point in the recording without losing your place on the other video.
- Nudge sync controls — Fine-tune alignment with ±0.1s, ±1s, and ±5s nudge buttons for each rider independently. Get both videos to show the same corner entry, braking board, or S/F line crossing — precisely.
- Frame-by-frame stepping — Step forward or backward one frame at a time. Inspect the visible approach, turn-in and exit. Frame stepping gives you time to inspect a moment that passes quickly at normal speed.
- Playback speed control — Slow down to 0.1x for detailed analysis or speed up to 2x to scan through a full session. Both videos always stay in sync at whatever speed you choose.
- Independent audio — Toggle sound on either video. Listen to one rider's engine note to spot gear selection differences, or mute both for visual-only analysis.
- Keyboard shortcuts — Keyboard shortcuts cover playback, panel selection, seeking and frame stepping. Space, arrows, Tab, frame step — once you learn the shortcuts, analysis flows without touching the mouse.
- Multi-language interface — Available in English, Polish, German, Spanish, and French. Auto-detects your browser language.

What you get with Pro
Rider Pro adds tools for measuring differences at selected references:
- Wait For Me — corner-by-corner sync — The faster rider reaches the braking board first? Freeze them. Let the slower rider's video keep playing until they reach the same point. The time between freeze and catch-up is your sector delta — the measured difference at your chosen reference. No GPS, no data logger, no telemetry hardware. Just two videos and your eyes.
- Sector timing and deltas — Every mark creates a sector entry with a precise time delta. The sector panel shows each section: who was faster, by how much, and the cumulative gap. Rename sectors to match your track — "T3 entry," "Back straight," "Chicane exit" — and build a complete picture of where time lives on the lap.
- Sync anchor point — Set a home position where both videos show the same physical point on track. Return to it anytime with one keystroke. No matter how deep you go into sector analysis, you're always one click away from your starting reference.
- Synced replay — After marking your sectors, replay the lap with alignment at those references. The faster video pauses while the other catches up, then both resume together. You can follow the visible lines and movements through each passage without repositioning the clips manually.
- Undo and recover — Made a bad mark? Undo the last sector split and jump back to where you were. Build your analysis iteratively without fear of losing work.
- Export sector data to MyRacing Planned Proposed export of marked sector analysis to your MyRacing profile.
- AI coaching on your sectors Planned Proposed support for discussing marked video sectors with AI Racing Coach using relevant track, motorcycle and riding-history context.
- Voice corner notes Planned Proposed voice observations linked to a point in the analysis, with transcription for later review.

Onboard Studio
How do I get the PRO features in Onboard Studio?
Onboard Studio's split timing and synced replay are included in Rider Pro. Choose Rider Pro when registering, or upgrade an existing account through Subscription in the app. Then open Onboard Studio from Tools. Basic video alignment remains free. See the alignment and comparison guide.
Does this upload my videos?
No. Your videos are never uploaded, stored, or accessed by us. Everything runs locally in your browser. Your footage never leaves your device. This applies to both the free and PRO versions.
What video formats are supported?
MP4, MOV, WEBM, and any other format your browser can play. Works with GoPro, DJI, Insta360, phone recordings, and any action camera output.
Can I compare videos that start at different times?
Yes. You can align the two recordings at a shared point on the track, even if the cameras started recording at different moments. Basic alignment is free. Follow the video-alignment steps.
Can I use this on my phone?
The tool works in mobile browsers but is designed for desktop or laptop. Keyboard shortcuts and the side-by-side layout work best with a full-size screen.
Free, browser-based, private.
