Camera rig solving
Easily solve and refine camera position, rotation, focal length and lens distortion parameters inside Nuke. With presets for popular camera rigs and custom rig support, Cara VR™ can handle footage from any 360° video shoot.
Cara VR features
Stitching
Cara VR’s GPU-accelerated Stitcher lets you create a high-quality 360° stitch for both mono and stereo output right in Nuke. Built on Ocula's disparity technology, Cara VR stitches seamlessly without line artifacts or ghosting, even on moving scenes, and easily exports STMAPs and UV maps.
Correction and color matching
Automatically correct exposure and white balance differences between cameras during the stitching process, producing a single exposure across all cameras with minimal manual adjustment. You can also produce subtle lighting effects, for example, by animating a change in gain over time.
360° tracking and stabilization
With a specialized feature-point tracker optimized to handle distortion and continuity at the edges of lat/long images, you can track and paint or merge directly on stitched 360° footage. Stabilization data from Nuke’s built-in Camera Tracker can also be used in the workflow.
VR compositing workflows
Cara VR's new GPU-accelerated Spherical Transform node speeds up compositing tasks by letting you use Nuke’s full set of compositing tools directly on 360° material, making roto, paint and tracking tasks easy.
360° stereo rendering and slit-scan shader
The version of Nuke’s ray trace rendering engine included with Cara VR offers additional support for stereo lens models, together with a slit-scan shader that can control the depth at the poles in 360° footage, resulting in a more pleasant VR viewing experience when looking up or down. The depth falloff can be controlled to match common stitching and rendering patterns, ensuring consistent results.
Headset review
With support for popular VR headsets, you can preview your project in Nuke’s viewer while playing it back from Nuke Studio’s timeline, without the need to export to a separate review application. Includes support for the HTC Vive and Oculus Rift CV1 on Windows and the Oculus Rift DK2 across Windows, Mac and Linux operating systems.
