13 | Basics Windows and Editors Reference > Settings preferences Linear Sets the unit of measure for operations that use linear values, for example, moving and scaling. The default is centimeters. Angular Sets the unit of measure for operations that use an angular value, for example, rotation. The default unit is degrees. Time Sets the working time unit for animation. The Time Slider displays time values in the unit chosen. The Time Slider values update when you change the time units. You can specify the time unit as frames or as clock values. Frame selections include: • 15 fps • Film (24 fps) • PAL (24 fps) • NTSC (30 fps) • Show (48 fps) • PAL Field (50 fps) • NTSC Field (60 fps) • 2, 3, 4, 5, 6, 8, 10, 12, 16, 20, 40, 75, 80, 100, 120, 125, 150, 200, 240, 250, 300, 375, 400, 500, 600, 750, 1000, 1200, 1500, 2000, 3000, and 6000 frames per second. Clock values include: • milliseconds • seconds • minutes • hours The terms frame and time refer to working time units as displayed in the Time Slider. Technically the term frame applies only when Time is specified in frames per second (fps). In general, time can refer to frames or to clock values. Keep keys at current frames By default when you change the current time unit, the times for any existing keys are modified so that playback timing is preserved. For example, a key set at frame 12film changes to frame 15ntsc when the current time unit is changed to NTSC, since they both represent a key at 0.5 seconds. When this option is on, it leaves the key at 12ntsc that was originally at 12film. The default setting for this option is off. The option turns on once the current time unit is changed. Basics 423
