Add data overlays
to workout videos.
How It Works
Clips align to your activity automatically.
Upload a .FIT file from your Garmin, Wahoo, or COROS and video clips filmed during that activity. MetricsOverlay places each clip at the correct point on the activity timeline and displays the data from that moment on the video.
Overlay Components
Everything your device records.
Heart Rate
Displays current BPM. Enable 'smart colors' to automatically change color based on heart rate zones. Gray when resting, green in zone 2, yellow in zone 3, orange in zone 4, red at max effort.
Speed & Pace
Shows velocity in your preferred unit. Displays as km/h, mph, or converts to pace format (min/km or min/mi) for runners. The value updates smoothly between FIT records.
Power
Displays cycling power in watts. Essential for structured training and pacing. Shows real-time wattage from your power meter, with smooth interpolation between FIT records.
Cadence
Shows pedaling cadence in RPM for cycling, or steps per minute for running. Helps viewers understand your rhythm and effort throughout the activity.
GPS Map
Shows your route with current position. The trail fades behind you, showing where you've been. Zoom level, trail length, and map style are all configurable. Position updates in real-time as the video plays.
Elevation Profile
Displays altitude as a graph showing the full route profile. A marker moves along the graph to show current position. Great for seeing upcoming climbs or celebrating descents.
Pace
Shows pace in min/km or min/mi format, calculated from speed. Ideal for runners who prefer to track effort in time per distance rather than raw speed.
Distance
Displays total distance covered in km or miles. Accumulates throughout the activity, showing how far you've traveled from the start.
Elapsed Time
Shows how long you've been riding or running. Displays in HH:MM:SS format, counting up from the activity start.
Altitude
Shows current elevation in meters or feet. Perfect for mountain rides and hikes where altitude awareness matters.
Grade
Displays the current gradient as a percentage. Positive values indicate climbing, negative values indicate descending. Helps viewers understand the terrain.
Vertical Gain
Shows total meters or feet climbed throughout the activity. Accumulates only uphill segments, giving a clear picture of climbing effort.
Vertical Descent
Displays total elevation lost during the activity. The counterpart to vertical gain, tracking all downhill segments.
Temperature
Shows ambient temperature in Celsius or Fahrenheit when your device has a temperature sensor. Useful for documenting conditions during the ride.
Customization
Make it yours.
Every overlay can be styled to match your video. Choose styles, colors, and fonts.

Smooth Data
Interpolation between records
Your device records data approximately once per second. But video runs at 30 or 60 frames per second. Without interpolation, the heart rate display would freeze for 30 frames, then jump to the next value.
MetricsOverlay calculates in-between values. If the FIT file says 142 BPM at second 5 and 148 BPM at second 6, frame 15 (halfway between) displays 145 BPM. The result is smooth, continuous data that moves naturally with your video.
This applies to all numeric values: heart rate, speed, power, cadence, altitude. GPS positions are also interpolated along the path between recorded coordinates.
GPS Visualization
Two ways to show your route
Overview Mode
Shows the full route at once. The trail draws as you progress through the activity. Use trim controls to highlight a specific section—perfect for showcasing a single climb or segment.
Follow Mode
Centers on your current position with adjustable zoom. The map rotates to match your direction of travel. Shows where you've been and hints at what's ahead.
Export
Two output modes
ProRes Video
Combines your original video with overlays burned in. You get a single .MOV file ready to upload or share. Uses ProRes 422 for quality.
output: video_with_overlays.mov
PNG Sequence
Exports only the overlays as transparent PNG frames. Import into DaVinci Resolve, Premiere, or Final Cut and layer over your original footage. Full control over compositing.
