The Foundry

Ocula 3.0v1

• O_VectorGenerator

This plug-in calculates consistent left and right motion vectors for reti-

ming. The motion estimation algorithm is based on the new disparity

engine in O_DisparityGenerator and delivers vectors that maintain stereo

alignment.

For more information, see VectorGenerator on page 91.

• O_Retimer

This plug-in lets you speed up or slow down a stereo clip based on the

left and right motion vectors calculated by O_VectorGenerator. You can

control the new timing of the clip using either the Speed or the Frame

control. Both controls are animatable.

For more information, see Retimer on page 98.

• StereoReviewGizmo

This gizmo lets you compare left and right views in various ways. For

example, you can use it for testing vertical alignment and colour matches

or measuring parallax. You can also convert it to a group to copy and

edit the internals. The gizmo is undocumented, but there are tool tips for

all the controls.

Improvements

Ocula 3.0 includes key improvements to the quality and accuracy of existing

plug-ins:

• All Ocula nodes

• BUG ID 22303 - Ocula nodes now cache results to disk to prevent

recalculations and to reduce memory overhead.

• O_Solver

• O_Solver has been rewritten to increase the accuracy and the ease of

use.

• The controls have been simplified.

• The node now uses a new, improved feature matching algorithm. This

delivers more accurate alignment data to downstream Ocula nodes.

• The Feature Matches display option has been renamed to Keyframe

Matches. As before, this shows matches at keyframes only.

• There’s a new Preview Alignment display option that lets you preview

the alignment of feature matches at both keyframes and non-

keyframes. This allows you to review how well the interpolated solve

works and whether additional keyframes are required. It also makes it

simpler to delete bad matches and preview the effect of user matches.

• In the Preview Alignment mode, there’s a new Match Offset control

that allows you to set the offset (in pixels) applied to the aligned

feature matches. You can also interactively control the offset using

the < and > keys on the Viewer. Increase the offset to view the
