How to chroma-key a telemetry overlay in CapCut, Premiere, DaVinci Resolve, and Final Cut
Overspeed exports your gauges on a solid chroma-key background instead of a finished video, so you stay in full control of the edit. Keying it out takes one step in any modern editor.
Overspeed exports the overlay layer only: your gauges rendered on a solid chroma-key background (magenta, green, or blue). You place that clip above your footage in your editor and key the background out, leaving just the gauges. Here is how in the four editors most people use.
Pick a key color that does not appear in your gauges. Magenta is usually safest for racing overlays, since green and blue often show up in track maps and bar gauges.
CapCut
- Add your footage to the timeline, then add the overlay clip on the track above it.
- Select the overlay and open Cutout, then Chroma key.
- Pick the color sampler and click the background color of the overlay.
- Raise Intensity until the background disappears, then nudge Shadow to clean the edges.
Adobe Premiere Pro
- Place the overlay on a video track above your footage.
- In Effects, find Ultra Key and drag it onto the overlay clip.
- In Effect Controls, use the Key Color eyedropper to sample the background.
- Set Output to Composite and adjust Matte Cleanup if any fringe remains.
DaVinci Resolve
- On the Edit page, stack the overlay above your footage.
- Open the Effects library and apply the 3D Keyer (or Chroma Keyer) to the overlay.
- In the Color page or Inspector, sample the background color.
- Refine the matte until the gauges have clean edges and the background is fully gone.
Final Cut Pro
- Drop the overlay as a connected clip above your footage.
- Apply the Keyer effect from the Effects browser.
- Final Cut auto-detects the key color; if needed, use Sample Color to pick the background.
- Use the Refine Edge tool to tidy the gauge outlines.
Tips for a clean key
- Match the overlay resolution and frame rate to your footage when you export, so the gauges sit straight over the video.
- Choose a key color your gauges do not use, to avoid keying out part of a gauge.
- If edges look rough, reach for the matte cleanup or refine-edge control in your editor rather than re-exporting.
