  3. 3. The project • Hosted in a research team at INRIA • Open-source, cross-platform nodal compositing software • Video editing and image processing • Funded since October 2013 as a result of an open-source project contest Alexandre Gauthier-Foichat 3/15
  4. 4. Compositing in short Image before matting Road Signs Final image Alexandre Gauthier-Foichat 4/15
  5. 5. Why we do it • Support OpenFX: standard to design visual effects plug-ins. Alexandre Gauthier-Foichat 5/15
  6. 6. Why we do it • Support OpenFX: standard to design visual effects plug-ins. • No open-source graphical software supporting OpenFX Alexandre Gauthier-Foichat 5/15
  7. 7. Why we do it • Support OpenFX: standard to design visual effects plug-ins. • No open-source graphical software supporting OpenFX • But used by many proprietary applications: Nuke,Scratch, Da Vinci resolve... Alexandre Gauthier-Foichat 5/15
  8. 8. Why we do it • Support OpenFX: standard to design visual effects plug-ins. • No open-source graphical software supporting OpenFX • But used by many proprietary applications: Nuke,Scratch, Da Vinci resolve... • Natron first targets education and research domains Alexandre Gauthier-Foichat 5/15
  9. 9. License • Most OpenFX plug-ins are commercial or released under BSD-style license. Alexandre Gauthier-Foichat 6/15
  10. 10. License • Most OpenFX plug-ins are commercial or released under BSD-style license. • GPL programs cannot load non GPL plug-ins Alexandre Gauthier-Foichat 6/15
  11. 11. License • Most OpenFX plug-ins are commercial or released under BSD-style license. • GPL programs cannot load non GPL plug-ins • This is probably why we don’t see many open-source softwares around OpenFX Alexandre Gauthier-Foichat 6/15
  12. 12. License • Most OpenFX plug-ins are commercial or released under BSD-style license. • GPL programs cannot load non GPL plug-ins • This is probably why we don’t see many open-source softwares around OpenFX • Natron is under Mozilla Public License (GPL compatible) Alexandre Gauthier-Foichat 6/15

  14. 14. Features for v1 • Implementation of a performant rendering engine Alexandre Gauthier-Foichat 8/15
  15. 15. Features for v1 • Implementation of a performant rendering engine • Animation support Alexandre Gauthier-Foichat 8/15
  16. 16. Features for v1 • Implementation of a performant rendering engine • Animation support • Support for OpenFX v1.3: Over 500 plug-ins available Alexandre Gauthier-Foichat 8/15
  17. 17. Based on many open-source libraries • Qt: Graphical user interface and core library • Boost: Serialization of the project • OpenImageIO: Image reading/writing • OpenColorIO: Color management Alexandre Gauthier-Foichat 9/15
  18. 18. Performances • Multi-threaded: Alexandre Gauthier-Foichat 10/15
  19. 19. Performances • Multi-threaded: −→ A main-thread handling user events and OpenGL rendering Alexandre Gauthier-Foichat 10/15
  20. 20. Performances • Multi-threaded: −→ A main-thread handling user events and OpenGL rendering −→ N render threads gathered in a pool • Thread pool controlled by Natron • Asynchronous tasks asked by the plug-ins Alexandre Gauthier-Foichat 10/15
  21. 21. Demand driven Alexandre Gauthier-Foichat 11/15
  22. 22. OpenFX support • Very stable API for writing visual effects. Alexandre Gauthier-Foichat 12/15
  23. 23. OpenFX support • Very stable API for writing visual effects. • Efficient: about 500 lines of code for a plug-in Alexandre Gauthier-Foichat 12/15
  24. 24. OpenFX support • Very stable API for writing visual effects. • Efficient: about 500 lines of code for a plug-in • Plug-ins can be GPU accelerated using external libraries like OpenCL or CUDA Alexandre Gauthier-Foichat 12/15
  25. 25. OpenFX current state • Many plug-ins, but most of them are proprietary. Alexandre Gauthier-Foichat 13/15
  26. 26. OpenFX current state • Many plug-ins, but most of them are proprietary. • About 80 are open-source: TuttleOFX Alexandre Gauthier-Foichat 13/15
  27. 27. OpenFX current state • Many plug-ins, but most of them are proprietary. • About 80 are open-source: TuttleOFX • We need more open-source visual effects plug-ins Alexandre Gauthier-Foichat 13/15
  28. 28. Conclusion • Natron is in beta stage now and it’s a good time to join us. • We need people making packages for all linux distributions • Non developers are welcome: bug reporting,feedback, demo reels, tutorials, translation... • Download at https://natron.inria.fr • Mailing list: natron@inria.fr Alexandre Gauthier-Foichat 14/15
  29. 29. Thank you • Thanks for your time ! • Any questions ? Alexandre Gauthier-Foichat 15/15
