Silhouette and Silhouette Paint FAQ

Posted Apr 15, 2021

What is Silhouette?

Since 2005 Silhouette has made its mark on film and television visual effects and post-production. Silhouette is an award-winning GPU accelerated compositing application that runs on macOS, Windows and Linux. Silhouette’s standout features are advanced rotoscoping tools and a non-destructive 32 bit, HDR paint system. Silhouette is also a node-based compositing tool with integrated planar tracking, keying, matting, warping, morphing, and a total of 400+ different nodes, including premier plugins Sapphire, Mocha Pro, and Particle Illusion wrapped in one integrated node-based package–all stereo enabled. Silhouette supports ACES color management via OpenColorIO. In 2019 the Silhouette team was recognized with Academy and Emmy technical achievement awards for the software’s contribution to the feature film and television industries.

Silhouette is now shipping version 2022 with multiple purchase, subscription and bundle options:

  • Silhouette Standalone + Multi-Host Plugin
  • Standalone Multi-Host Plugin only
  • Bundles
    • Bundle: Silhouette + Mocha Pro (Standalone + Multi-Host)
    • Bundle: Silhouette Plugin + Mocha Pro Plugin (Multi-Host)
    • Boris FX Suite (Silhouette, Mocha Pro, Sapphire, Continuum, and Optics).

Does the Silhouette 2022 Plugin replace the Silhouette Paint Plugin?

Yes, the fully featured Silhouette interface for roto, paint and compositing can now be launched as a plugin from industry standard VFX applications. In previous versions, the “Silhouette Paint Plugin” was limited to paint only functions. Now, the entire Silhouette node based workflow for roto, paint, tracking, warping, keying and compositing is a plugin for Adobe After Effects and Premiere Pro and OFX hosts: Foundry NUKE, Blackmagic Resolve and Fusion, and Autodesk Flame.

Existing Silhouette Paint Plugin customers with an active subscription can install the Silhouette 2022 Multi-host Plugin and their existing license will work for the duration of the subscription.

What is the difference between Silhouette and Silhouette Plugin?

The Silhouette Standalone and Plugin have the same feature set with the main difference being the Plugin is responsible for loading source inputs and final rendering. Although the Plugin doesn’t allow more than three inputs, additional sources can be added directly within Silhouette. In addition, the plugin does not include Sapphire and Particle Illusion.

I own the Silhouette Standalone, do I have to pay for the Plugin?

The Silhouette Plugin is included with all new Silhouette 2022 purchases and your license enables the ability to run inside Adobe or supported OFX hosts. You can either run the Silhouette Standalone or the Silhouette Plugin at one time on the same CPU, based on the amount of licenses you own.

Silhouette Standalone owners on current upgrade and support plans also receive the Silhouette Plugin for free. Your current license will work and does not require reactivation. If you are unsure if you qualify, contact our sales team.

Silhouette owners running legacy versions and are not on an upgrade and support plan, do not qualify for the free Silhouette Plugin.

Are projects compatible between the Silhouette Standalone and Silhouette Plugin?

Yes, Silhouette Standalone and Plugin projects are interchangeable with a couple of caveats.

  1. The sources need to be reconnected when opening a Plugin project in the Standalone.
  2. The OCIO colorspace may need to be adjusted when opening Plugin projects in another host or in the Standalone as some host applications perform colorspace conversions.

Does the Silhouette Standalone and Plugin support floating licenses or VM licensing?

Yes, Boris FX offers Enterprise licensing options for customers with 5 or more users that require floating licenses or virtual license serving. Please visit our Enterprise Program page to learn more.

What 3rd party OFX plug-ins does Silhouette support?

What shape formats can Silhouette export?

Silhouette can export to the following shape formats: Autodesk®/Discreet® gMask, Elastic Reality®, Eyeon Fusion®, Nuke® and Shake® 4.x SSF shapes.

What is the difference between the integrated Mocha tracker and the Mocha Pro plug-in for Silhouette?

The integrated Mocha tracker tracks directly within the Silhouette user interface and links to Silhouette’s spline tools. The Mocha Pro plug-in launches the Mocha user interface and provides access to GPU-accelerated tracking and object removal, stabilization, lens calibration, AdjustTrack module, 3D camera solver, stereo 360/VR support, and more.
