Blender compositor - Good and bad news

First the good news: The developer of the OpenCL branch now has a Color Correction implements Node, which is at Nuke's inspired color correction node. And he has also programmed some simple masks nodes, which is now more complex color grading will be possible. If, after the Google Summer of Code also the Tracker is added, it is likely in the fall may already have a pretty nice tool box for find professional compositing. And now not quite so nice for: Anyone who has ever grappled with OpenCL, white kernels that compositing can always be compiled until runtime, if they are to be effective. This will take on complex projects, but up to a minute. For laymen simply said: Before you calculate an Composing with hundreds of nodes can be created only once the program for the graphics card. After the effect is running very fast. But only until you change a parameter, so what happens when you work constantly. Then must always be first again recompiled. The CPU can start already during the compilation, however, and was the most complex compositing always finished before the graphics card was ever ready to go. At least there's been a few attempts to tackle the problem, but they must be analyzed yet. We can finally announce some good news: For the Blender Day on 09/07/2011 wants the developer to show a stabilized version with which you probably own then the first walking trials can start. We estimate that the initial builds quickly on Graphicall will be available, though probably only once only available on Linux.
