HIERO gives you an all-in-one shot management, conform, edit and review solution that makes it simple to move offline to online, organize projects and stay on top of review and versioning at every stage.
HIERO has been built to work ‘out of the box’ with NUKE, and can also be custom-scripted to work with other applications in your facility.
Because HIERO is open and scriptable via the Python programming language, it is an editorial tool that fits naturally into any VFX pipeline.
HIERO is slated for release in November 2011 will be available on OS X and Linux, with Windows to follow.
