As of version 13.03.10, there are now several video filters available. Thanks to Movit and MLT, these filters run on the GPU using OpenGL Shading Language for speedy, high quality, 16-bit (per color component) linear float processing! There are also some CPU-based ones (8-bit integer with gamma); you switch between them by using the GPU Processing option in the Settings menu. This provides a convenient way to compare them. The GPU filter processing even works in conjunction with simultaneous SDI/HDI monitoring. Also, it works for background encoding jobs. The screenshot on the Shotcut homepage has been updated. Oh yeah, I almost forgot to mention that with the GPU-powered Color Grading filter, we now offer 3 way color wheels. :-)
