You can enable the Stereoscopy feature in one of the following ways:
Selecting a Raster for Stereoscopy
You want to only select a stereoscopic raster if you are connected to a proper stereoscopic device (e.g., Stereoscopy projectors (two projectors or one), or a 3D monitor). When you are playing out your footage to a dual link device, each eye is assigned to one link. The Left Eye always runs through the A Link and the Right Eye through the B Link. Refer to the Autodesk Lustre Hardware Setup Guide.
To select a stereoscopic raster:
(a) Video/Graphics Raster button (b) Link Type button (c) Format button
Enabling the Stereoscopy Button
You can disable and re-enable the Stereoscopy feature by using the Stereoscopy button. You would enable the Stereoscopy button when you are assembling an EDL independently for each eye to create a two-layer timeline. You would then convert it to a Stereo timeline.
