Abstract
A set of tools in a media composition system for stereoscopic video provides visualizations of the perceived depth field in video clips, including depth maps, depth histograms, time-based depth histogram ribbons and curves displayed in association with a media timeline, and multi-panel displays including views of clips temporally adjacent to a clip being edited. Temporal changes in perceived depth that may cause viewer discomfort are automatically detected, and when they exceed a predetermined threshold, the editor is alerted. Depth grading tools facilitate matching depths in an outgoing clip to those in an incoming clip. Depth grading can be performed automatically upon detection of excessively large or rapid perceived depth changes.
