ReelSteady
Also known as: ReelSteady Go, GoPro ReelSteady
Gyro-based stabilization software, later bought by GoPro, that smooths footage after shooting using the camera motion data and became popular with FPV pilots.

What it means
ReelSteady started as an independent tool that used the gyroscope data recorded by action cameras to stabilize footage in post. Its fame came from FPV flying: pilots mounted a GoPro with HyperSmooth off, then let ReelSteady remove the jitter from props and wind while keeping the aggressive moves and the sense of speed that a gimbal would flatten.
GoPro acquired the company and folded much of the technology into its own cameras and software. That history is why the name still appears in forum posts and tutorials, and why later in-camera stabilization on GoPros feels so similar to what the standalone app produced.
How it works in practice
The workflow mirrors other gyro tools. You record at a wide setting with stabilization off, keep the original files untouched, and load them into the app, which reads the embedded motion data and renders a stabilized copy. Horizon leveling and a smoothness slider let you decide how locked the shot should feel.
Today many pilots use the open-source Gyroflow for the same job, since it supports more cameras and flight-controller logs. If you have older naked GoPro footage or follow an older tutorial, the steps are close enough that you can switch tools without reshooting anything.
What to watch out for
Post stabilization needs the original gyro data. Files trimmed or re-saved by a phone app, or clips recorded on cameras that do not log motion, simply cannot be processed, so copy the card first and stabilize from those copies.
Do not combine it with in-camera stabilization. Running gyro software on footage that EIS already smoothed tends to produce warping edges, and fast moves with a slow shutter speed still keep their motion blur, which no stabilizer can remove. Keep one unstabilized copy of every flight as well, so you can try a different tool or setting later without losing the original.
How RawClip handles it
RawClip works from the finished video and does not stabilize clips. Stabilize FPV or action footage in your preferred tool first, then upload the exported files, and the AI picks the strongest moments for your highlight.
