Scene Motion Blur Turns on the scene motion-blur on page 8117 effect for the whole scene. This is different from object motion blur on page 8063, which creates motion blur for individual objects in the scene. When you render with Scene Motion Blur activated, the Render Progress dialog tells you which subsample is being rendered. The information appears in parentheses to the right of the "Rendering Image" text. Duration Sets the virtual shutter speed for motion blur. When set to 1.0, the virtual shutter is open for the entire duration between one frame and the next. When set to a smaller number, such as 0.25, the number of subdivisions specified in the Duration Subdivision field will be rendered within the specified portion of the frame (in this example, in the first fourth of the duration between one frame and the next). Duration Subdivisions Determines how many sub-frame slices are rendered within the Duration. The default is 2 slices, but you'll want at least 5 or 6 to get a decent effect. Dither % Sets the amount of dithering on page 7956 between blurred pixels of overlapping frame slices. If Dither % is set to 0, no dithering occurs. Scene Range group Scene Start/End Sets the range of scene frames to be rendered. Lock Range Bar to Scene Range Becomes available when you deselect Lock To Video Post Range. When it's available, the End spinner is disabled and locked to the Video Post range. When you change the Start spinner it automatically updates the End spinner based on the Video Post range set for this event. If you turn off Lock Range Bar To Scene Range, you can change either Start or End spinners to whatever you want. This allows you to keep your scene range locked to its native length, and still provides flexibility for mapping an arbitrary scene range to an arbitrary Video Post range. Lock to Video Post Range Renders the same range of scene frames as Video Post frames. You can set the Video Post range in the Execute Video Post dialog. Video Post Parameters group VP Start Time/End Time Sets the starting and ending frames for the selected event within the overall Video Post queue. Video Post renders the event over the number of frames specified here. Add Scene Event | 6813
