Your ride's data,
on your ride's video.
Sointula overlays live gauges — speed, heart rate, power, maps, and more — onto your GoPro footage, driven by your Garmin FIT file and the camera's own telemetry. Arrange them on the video, scrub the timeline, export a finished MP4.
Beta 9.9.9 · macOS 13+ · Windows 10+
Sointula is beta software
It's free to use while we finish it, and we'd love your feedback — but expect rough edges, keep backups of your footage and projects, and know that things may change between builds.
Beta builds expire six months after they're built. The app reminds you of its expiry date on first launch; grab a newer build from this page before then and your projects carry straight over.
Features
Twenty-three gauges
Speedometers, zone bars, track maps, elevation profiles, G-force, lean angle, and more — drag them from a live-rendered palette onto your video.
Your ride's data
Reads Garmin FIT files — speed, heart rate, power, cadence, grade, and dozens more channels — plus the GPS, accelerometer, and gyro embedded in GoPro footage.
Multi-clip timeline
Import a whole ride's worth of clips; they order themselves by recording time. Trim, scrub, and shuttle with data graphs under the timeline.
Gauges are JavaScript
Every gauge is a script you can open and edit — a Canvas-style API with live reload. Tweak ours or write your own from scratch.
Layouts that stick
A snap grid keeps gauges aligned, and layout templates let you save your favourite arrangement and recall it in any project.
Export ready to share
Renders your overlays into a finished MP4 at source, 1080p, or 720p — ffmpeg is bundled, so there's nothing else to install.
