Movie Modifiers
From ZBrush Info
The following controls are used to adjust the Movie.
Frame Size: Factor by which the actual recorded images will be scaled to produce the final movie. To minimize the amount of space your movie takes, set this just high enough to show the amount of detail you need to show.
Auto Zoom: When any value other than 0, only a portion of the window or document will be shown, and the camera will pan to follow the mouse. The size of the area around the mouse that is shown is determined by the value of this slider. There's a certain amount of tolerance built in; small mouse movements won't cause the camera to pan, which reduces unnecessary panning.
Recording FPS: Number of frames per second used when recording the movie. Small values reduce the movie file size, but result in a jerkier animation.
Playback FPS: Determines how quickly the movie will play back. If this is equal to the Recording FPS, the movie will play at the speed it was recorded at; if this is double the Recording FPS, the movie will play at double speed; and so on.
Snapshot Time: When inserting a snapshot into the movie using Snapshot, determines how long the snapshot will be visible when the movie is played.
Skip Menus: When on, menus will not appear in the animation.
Antialized Capture: Antialiases output, at possible cost of increased processing time, blurring of pixel-level details, and perhaps a small effect on file size. Normally this should be left on.
OnMouse: When OnMouse is active, then the movie will record only those actions that occur when the mouse is active. Basically, this means that clicks on controls, and sculpting and moving the model will be shown, but not movements of the mouse around the screen or over controls.
Cursor Size: Can be used to increase the size of the cursor used in the movie, which can make the cursor more noticeable is situations where it would otherwise be difficult to see.
Below the Cursor Size slider are modifiers for use when recording turntables.
