3D Glasses effect
The3DGlasseseffectcreatesasingle3Dimagebycombiningaleftandright3Dview.Youcanuseimagesfrom3D
programs or stereoscopic cameras as sources for each view. The method you use to create the combined images
dictates how you view them. For example, you can use the 3D Glasses effect to create an anaglyphic image, which
contains two slightly different perspectives of the same subject that are tinted contrasting colors and superimposed
on each other. To create an anaglyphic image, first combine views and tint each one a different color. Then, use 3D
glasses that have either red and green lenses or red and blue lenses, to view the resulting image stereoscopically.
3D Glasses effect: Balanced Color Red Blue selected (left) and Interlaced Upper L Lower R selected (right)
To avoid problems with flipped views, keep the following guidelines in mind:
• Use the same vertical dimensions for the composition and source images. One pixel difference produces the same
result as moving the position one pixel vertically.
• Make sure that the image’s Position values are whole numbers (such as 240 instead of 239.7).
• If your left and right view images are interlaced, deinterlace them before applying the 3D Glasses effect. This
avoids field mismatch.
• Because the 3D Glasses effect creates interlaced frames, do not select an interlace option in the Render Settings
dialog box.
Adjust the following controls for the 3D Glasses effect:
Left View, Right View Specify the clip to use as the left or right view. You only need to apply 3D Glasses to one clip
in a sequence. If you use a second clip, make sure that the two clips are the same size. The second clip does not need
to be visible in the sequence.
Convergence Offset Specifies 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, there is no
need to change this value. Keyframing this value may result in erratic animation.
Swap Left-Right Swaps the left and right views.
3D View Specifies the rendering mode the effect uses to combine the views.
• Stereo Pair Scales both images to fit side by side within the effect’s bounding box. Select Swap Left-Right to create
cross-eyed vision. Selecting Stereo Pair disables Convergence Offset.
• Interlace Upper L Lower R Takes the upper (first) field from the Left View, and the lower (second) field from the
RightView,andcombinesthemintoasingleorasequenceofinterlacedframes.Usethisoptionifyouwanttoview
the results with polarized or LCD shutter glasses. Select Swap Left-Right to switch fields.
• Red Green LR Tints the Right View red, and the Left View green using the luminance values of each image.
• Red Blue LR Tints the Right View red, and the Left View blue using the luminance values of each image.
