Rainbox releases Dume, a versatile and open source media encoder for the masses.
If you are one of those people that are itching to ditch Adobe Media Encoder, you now have another alternative. Nicolas Dufresne and the Rainbox team released DuME, a free, open-source, and multi-platform media encoder that, as it happens, is also fast.
DuME uses FFmpeg for transcoding, which makes it very fast and versatile. However, DuME offers some other features not available in FFmpeg (like DWA support for EXR files).
Topping all that off, DuME is also able to render and transcode Adobe After Effects projects.
