Flightline FPV Tools

FPV tools for pro pilots

You flew that line clean. Your footage should show it.

The O4 filter takes the false shake out of DJI O4 footage before Gyroflow, without touching a frame of your video.

Flightline is a forthcoming suite of FPV tools for pro pilots. We're starting with the O4 filter and management dashboards, and the O4 filter is flying with its first pilots now.

Roll, as the O4 recorded it

An illustration of what the filter does. Your real moves stay; the fast roll the lens never had goes, so Gyroflow stops stabilizing against it.

How It Works

  1. 1

    Drop your clips in

    Flightline reads the motion data your O4 wrote into each clip, right there on your Mac.

  2. 2

    It filters the motion, not the video

    Roll gets smoothed harder than pan and tilt, and every frame of video stays exactly as you shot it.

  3. 3

    Open the copy in Gyroflow

    A copy ending in _o4filter lands next to the original. Stabilize and export the way you always do.

0 bytes

of your video change. Only the motion data does.

About 2.5 s

Your Gyroflow

and your workflow. Nothing new to learn.

Software + hardware + art = magic.
I'm Nicholas Young, and I live where software, hardware and FPV meet. I was an early contributor to Node.js and Rust, I design the Fictive Air line of sub-250 g cinematic quads, my rates and OSD presets ship in Betaflight's official library, and I've built tools that run on HDZero goggles and pull live video out of DJI Goggles 3. When a clip comes back shaking from a flight that felt smooth, that's a software problem sitting on top of a hardware one, and fixing it is as much craft as the shot itself. Flightline is where I put those fixes, so your footage looks the way the flight felt.

Made for pilots who care how the footage looks.
