Free compositing app ButtleOFX goes alpha


Libre Graphics World reports on the release of ButtleOFX, a new open source compositing app.

For those who haven't heard of ButtleOFX yet, it's an application for VFX compositing that is built on top of TuttleOFX, a free commercial-grade framework for compositing with OpenFX plugins (that is, your Sapphire, Keylight etc. plugins should work).ButtleOFX is currently being developed by 5 students from IMAC Engineering school — Anthony Guiot, Baptiste Moizard, Jonathan Douet, Lucie Delaire, Virginie Lalande — led by Fabien Castan, one of major contributors to TuttleOFX.

It's the second team of students working on this project. For the new round of development they decided to focus on improving the user experience before adding more features.

Builds are available for Linux only at this moment, with Windows coming up. Mac hasn't been planned yet.

I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.


  1. This looks cool. I hope that this project becomes as successful as Blender. There aren't many open source options in the compositing field. I'll have to wait till there is a windows build available so I can test it out.

  2. this looks like it does a very nice job of simple compositing, but doesn't really seem to offer much over blender yet - perhaps in performance. It will be great to see it grow, hopefully into deep 3d compositing and so on.
