Preview — markers are shown at the scale they'll have on this screen.
Exit anytime with Esc, a double-tap or double-click, or the on-screen button. Tap once to bring the button back. 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.
