Preview stereo and spatial video in Final Cut Pro for Mac

By default, a stereo video project in Final Cut Pro shows one eye only (the left eye or the right eye). For footage shot on iPhone, it’s best to show the hero eye while editing because it has the highest visual quality.

When working with stereo video in the viewer, you can show the views for both the left and right eyes simultaneously. These special view options allow you to objectively assess the parallax and alignment of stereo video.

Select a stereo video clip in the Final Cut Pro browser.
Be sure to confirm the stereoscopic settings for the clip.
Click the View pop-up menu in the upper-right corner of the viewer, choose Show Stereoscopic As, then choose an option from the submenu:
- Left Eye: Shows just the view for the left eye. If the left eye is the hero eye, “(Hero)” appears after the name.
  You can also choose the Left Eye view by pressing Control-Option-Command-1.
- Right Eye: Shows just the view for the right eye. If the right eye is the hero eye, “(Hero)” appears after the name.
  You can also choose the Right Eye view by pressing Control-Option-Command-2.
- Both Eyes: Shows the left and right eyes side by side.
  You can also choose the Both Eyes view by pressing Control-Option-Command-Grave Accent (`).
- Anaglyph: Shows a simultaneous view from both eyes. The red channel for the left eye and the blue and green channels for the right eye are composited together. You can use this view to compare parallax and alignment with or without standard red/cyan anaglyph glasses.
  You can also choose the Anaglyph view by pressing Control-Option-Command-3.
- Anaglyph Monochrome: Shows the Anaglyph view in grayscale. This view makes it easier to see the image in stereo without interference from bold colors in the scene. Luminance from the left and right sources is composited together using the red channel for the left eye and the blue and green channels for the right eye. You can use anaglyph glasses to see the image without interference from the native colors in the source image, or use this view without glasses to compare parallax and alignment.
  You can also choose the Anaglyph Monochrome view by pressing Control-Option-Command-4.
- Anaglyph Outline: Shows edges in the image and lets you set the parallax using the Convergence control, which adjusts the apparent convergence point (the perception of distance to an element) in the scene. Edges with red on the left side indicate positive parallax (farther away than the convergence point), and edges with red on the right indicate negative parallax (closer than the convergence point). This is the most precise view for assessing the actual parallax in a scene. You can use anaglyph glasses to preview the stereo effect.
  You can also choose the Anaglyph Outline view by pressing Control-Option-Command-5.
- Superimpose: Composites the views for the left and right eyes at 50 percent opacity so they are both visible simultaneously. This view is useful for spot-checking the output, but does not help identify specific left-right parallax cues. You can’t use anaglyph glasses with this view.
  You can also choose the Superimpose view by pressing Control-Option-Command-6.
- Difference: Compares the pixel color values of the views for the left and right eyes and produces a monochrome result. No difference results in gray output, but dissimilar pixels appear in a range from dark to bright. This view is ideal for flagging vertical disparities. You can’t use anaglyph glasses with this view.
  You can also choose the Difference view by pressing Control-Option-Command-7.
