White Balance – Renders objects in the scene that have the specified color as white in the image. Bitperfect 3 0 1.

Frame rate and motion blur are important aspects of video quality. This demo helps to show the visual differences between various frame rates and motion blur. A few presets to try out:
- 15 vs. 25 vs. 48 vs. 60 frames per second (with motion blur exaggeration)
Motion blur is a natural effect when you film the world in discrete time intervals. When a film is recorded at 25 frames per second, each frame has an exposure time of up to 40 milliseconds (1/25 seconds). All the changes in the scene over that entire 40 milliseconds will blend into the final frame. Nxpowerlite 8 0 8 meters. Without motion blur, animation will appear to jump and will not look fluid.

There's no doubt in my mind that we're heading towards movies being shot and projected at higher frame rates.
