Nexrender

Nexrender automates rendering in Adobe After Effects so that video can be produced from data and templates rather than by hand. A developer defines a job that points to an After Effects project, supplies assets and values, and nexrender renders the result. It is built with Node.js and aimed at teams producing many personalized or templated videos, such as marketing variations.

A job can include static assets, data assets that change text or other fields, and script assets, along with actions that run before or after rendering. Dynamic parameters let scripts receive values at render time. For larger workloads, the nexrender-server and nexrender-worker components provide network rendering across machines, and there is also a command-line interface and a programmatic API. The project documents running under Windows Subsystem for Linux and describes job states and custom actions.

Nexrender is released under the MIT license and has a related ecosystem of external packages and community projects. It still depends on Adobe After Effects being installed on the machines doing the rendering, so it automates an existing licensed tool rather than replacing it.
