    Preview — markers are shown at the scale they'll have on this screen.

    Exit anytime with Esc, double-tap, or the on-screen button. The screen stays awake while filming.

    Filming tips

    • Markers are a darker shade of the same color on purpose — they key out with the background but give your tracker something to lock onto.
    • Lower the brightness here if the screen blooms or spills color on camera.
    • Use the scrollable mode when the shot shows someone scrolling — the markers move with the page, so the replacement content can scroll to match.
    • Match your camera's shutter speed to the screen to avoid flicker and banding.
