How to Capture Video
In order to preview a ramp, some video must have been captured into the computer. The RPC currently does not have any features that allow video capture, so you must use third party software. The ARRI Technical Note
The RPC can open a variety of video file formats, including: QuickTime Movies (.mov), AVI files (.avi), DV files (.dv),
When using a SONY VAIO Laptop, please be aware that you should not run the “DV Gate Motion” software at the same time you are running the Ramp Preview Controller.

•Now push the mouse button down and keep it held down. A Preview Trigger will appear on the Timeline. Don’t let go of the mouse button yet; instead move the cursor to the left or right to scrub through the movie. Once you get to the place in the movie where you want the Preview Trigger to occur, let go of the mouse button.
