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).

• Iftheleftandrightviewimagesareinterlaced,deinterlacethembeforeusing3DGlassestoavoidfieldmismatch.

• 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.

Whenyouworkwithredandblueimages,thebluecoloringlasseswithredandbluelensesisactuallycyan,notblue.

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.

Left View, Right View The layer to use as the left or right view. You need to apply 3D Glasses to only one layer in a

composition.Ifyouuseasecondlayer,makesurethatthetwolayersarethesamesize.Thesecondlayerdoesn’tneed

to be visible in the composition.

Convergence Offset Theamountthatthetwoviewsareoffset.Usethiscontroltorealignuncalibratedcameraviews

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.

Swap Left-Right Swaps the left and right views.

3D View How the views are combined.

• Stereo Pair Scales both layers to fit side by side within the effect layer’s bounding box. Select Swap Left-Right to

create cross-eyed vision. Selecting Stereo Pair disables Convergence Offset.

• Interlace Upper L Lower R Takestheupper(first)fieldfromtheLeftViewlayer,andthelower(second)fieldfrom

the Right View layer, and combines them into a sequence of interlaced frames. Use this option if you want to view

the results with polarized or LCD shutter glasses. Select Swap Left-Right to switch fields.

• Red Green LR Tints the Right View layer red, and the Left View layer green using the luminance values of each

layer.

• Red Blue LR TintstheRightViewlayerredandtheLeftViewlayerblue(cyan)usingtheluminancevaluesofeach
