In the camera, you have an option of what time base you’re project will be. So, I can choose 23.976, 24, 25, 29.97, 30, 59.94, and 60. I think that’s all of them. Then, you need to choose what frame rate you’ll be shooting. Most of the time, we are shooting 24 fps, with a 1/48th shutter. You have the option to activate varispeed. This shot was 48fps, 1/96th shutter, in a 23.976 time base, which means, this shot, to the editor, is a 23.976 clip, with slower motion. I have been doing some experimentation in Twixtor, and I’m getting slightly better results.
