View stereoscopic 360° clips in the 360° viewer
When working with stereoscopic 360° media in the 360° viewer, you can show the views
for both the left and right eyes simultaneously. These special view options in the 360°
viewer allow you to objectively assess the parallax and alignment of stereoscopic sources.
1. Select a stereoscopic 360° video clip in the Final Cut Pro browser.
Be sure to confirm the stereoscopic settings for the clip.
2. View the clip in the 360° viewer.
3. Click the Settings pop-up menu at the top of the 360° viewer and choose an option
from the Stereoscopic section:
• Left Eye: Shows just the view for the left eye.
• Right Eye: Shows just the view for the right eye.
• 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.
• Anaglyph Monochrome: Shows the Anaglyph view in grayscale. This view makes
it easier to see the image in stereo. 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.
• 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 stereoscopic space. Edges with red on the left side
indicate positive parallax (farther away than the convergence point), and red on the
right indicates negative parallax (closer than the convergence point). As a bonus,
you can use anaglyph glasses to preview the stereoscopic 3D effect.
This is the most precise view for assessing the actual parallax in a scene.
• 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.
• 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 or inconsistencies in stitching. You can also adjust the apparent
convergence point in stereoscopic space without a VR headset. You can’t use
anaglyph glasses with this view.
