IMPEdit is a commandline based postprocessing and nonlinear editing (NLE) tool for animations rendered on the Internet Movie Project (IMP) renderfarm. The idea is to postprocess the rendered frames on the renderfarm server prior to MPEG encoding.

It's written in Java and hence should run on any platform that supports Java. To run IMPEdit a Java Runtime Environment (JRE) is required, the latest release can be downloaded here.
