Two laps, side by side, on the same scrubber.
Open any two laps — from one session or two different days — and watch them play in lockstep. The shared transport keeps both videos seek-synced, the delta pane shows where you're gaining and losing time, and the GPS track map draws both lines so you can see the lift exactly where it happens.
Fourteen widget types. Drop any of them on the canvas.
Bind any data channel to any widget. Restyle with the theme picker. Thirteen of the fourteen are below — the image overlay takes your own PNG, so there's nothing to show until you drop one in. These are the real widgets the editor ships — rendered here with the same canvas pipeline, just frozen on sample telemetry.
Build your own widgets. No code.
The Widget Studio is a visual editor for your own overlay widgets — gauges, readouts, shift lights, lower thirds. Add layers from the palette, drag them into place, and bind them to your telemetry with an input and output range, or a one-line formula when you need one. Preview on built-in demo data, then drop the widget on your video like any other.

- Arcs and tick scales for gauge faces
