This sets the rates at which "proxy" and "render" modes cache to the drive.Paul Fierlinger wrote:BTW, what is the function of the Data Rate and Compute?
When you use the 'compute' function, it tests the maximal (optimal?) rate in which data can be written to the drive you set as a scratch drive.
If you use the computed data rate, it will render in high quality. But despite the computed rate, the preview is still often not smooth (something I can't figure out why...). In order to work better, you can manually set the data rate to a lower factor, and the rendering time will be much quicker. In fact, usually you can set the rate to much lower than the computed rate, and you will still see no degradation in image quality, but since less information per frame was written to the drive, it will read off the drive at a higher rate.
When I'm testing animation, if "realtime" mode slows down my previews, I usually work in "proxy" mode at 10.00 MB/s. It gives me enough image resolution to see what's there, and provides full frame rate to preview the motion.
