To avoid problems with flipped views, keep in mind the following guidelines:
• Use the same vertical dimensions for the composition and source images. A one-pixel difference produces the
same result as moving the position one pixel vertically.
• Make sure that the layer's Position values are whole numbers (such as 240 instead of 239.7).
• If the left and right view images are interlaced, deinterlace them before using 3D Glasses to avoid field mismatch.
• Because 3D Glasses creates interlaced frames, don't select an interlace option in the Render Settings dialog box.
Ghost effects occur if the luminance values of one color exceed those of another color to such an extent that you can
see the first color through the wrong lens of anaglyph glasses. For example, an excessive red luminance value
becomes visible through the blue lens. If you adjust the Balance value, test the results on the final output media. If
you set the Balance value too high, a reversed shadow may appear.
When you work with red and blue images, the blue color in glasses with red and blue lenses is actually cyan, not blue.
Red and cyan are complementary colors, producing the best separation because they filter each other out more
efficiently. When you work with red and green images, it may appear that the green isn't as bright as the red. However,
viewing the images with red and green lenses produces an even result because green has a higher luminance value
than red.
The layer to use as the left or right view. You need to apply 3D Glasses to only one layer in a

composition. If you use a second layer, make sure that the two layers are the same size. The second layer doesn't need
to be visible in the composition.
The amount that the two views are offset. Use this control to realign uncalibrated camera views

of rendered material. Photos or images rendered from 3D programs are generally misaligned and require a negative
Convergence Offset value. If the original footage was shot with correct convergence, changing this value isn't
necessary. Keyframing this value may result in erratic animation.
