Previews
In addition to displaying the output of a tool, the display views are also used to display flipbook previews and do file playback of image sequences and AVI or MOV files straight from disk.
RAM Flipbook Previews
RAM Flipbook Previews are preview renders that exist entirely within RAM. They are created by holding down the Alt key while dragging a tool into the display views, or by selecting Create>Play Preview from the tool context menus.
Once the preview is done rendering, the flipbook will be loaded into the view, temporarily overriding any tool currently displayed in the view. Playback controls appear in the bottom right corner of the interface beneath the tool controls, a Frame counter appears in the corner of the view, and a play/pause button is added to the right of the view's bottom toolbar.
To remove the preview and destroy the flipbook, right-click on the view and select Remove Preview.
Other options on the view's context menu allow enabling looped or ping-pong playback, or (as of Fusion 5.1) Fullscreen mode, which hides the rest of Fusion's interface. View controls are not displayed in Fullscreen mode. To exit Fullscreen mode, deselect it from the context menu, or press the Esc key.
It is also possible to "trim" the flipbook, to skip playback of the first or last few frames. This can be done using the scrub bar in the transport controls that appear at the bottom right of Fusion's window. Ctrl+drag the scrub bar to set or change the frames to be played, or right-click on it to set or reset the in & out points via a menu.
Mouse shortcuts
While the flipbook preview is showing, it can be played or scrubbed using only the mouse. These shortcuts work in Fullscreen mode as well.
- Playback
- Double-click the left mouse button anywhere in the view to start playback.
- Scrubbing
- Hold down the right mouse button and drag the mouse left or right to scrub through frames in the flipbook.
Keyboard shortcuts
While the flipbook preview is active, playback and frame advance can also be done with the keyboard. These shortcuts work in Fullscreen mode as well.
- Playback
- The spacebar can be used to start or stop playback. Hold down Shift while pressing the spacebar to play in reverse.
- Forward/reverse
- The left and right arrow keys will move the flipbook to the previous or next frame. Hold down Shift as well to jump back or forward 10 frames at a time. Ctrl+left will return to the first frame of the flipbook, while Ctrl+right jumps to the last frame.
File Sequence Previews
When a loader or saver is selected, the file sequence or footage loaded by that tool can be played back in the display view by pressing play on the transport controls that appear in the bottom of the tool controls region.
When the play button is selected, the file preview becomes active and Fusion will load the images as quickly as possible and play them to the display view. By default, the left display view is used for this purpose. That default can be changed using the Preview preferences. By changing these preferences, it is also possible to simultaneously play the file sequence to installed video hardware (this may decrease playback performance).
As with flipbooks, trimming in & out points can also be set for file sequence previews, using the scrub bar in the transport controls that appear at the bottom right of Fusion's window. Ctrl+drag the scrub bar to set or change the frames to be played, or right-click on it to set or reset the in & out points via a menu. By default, trimming done here while a Loader tool is selected will be mirrored in the Loader's Trim In/Out controls. This can be disabled using the scrub bar's context menu.
While the file sequence preview is enabled, normal viewing of tools to that display view is disabled. To return to normal operations, select another tool or blank area of the flow.
