Looping Options
The Loop button can be toggled to enable or disable looping during playback. You can right-
click this button to choose the looping method that’s used:
Playback Loop: The playhead plays to the end of the Time Ruler and starts from the
beginning again.
Ping-pong Loop: When the playhead reaches the end of the Time Ruler, playback
reverses until the playhead reaches the beginning of the Time Ruler, and then
continues to ping-pong back and forth.
Render Range Fields
The two time fields on the left side of the transport controls are used to modify the Render
Range. You can enter time values in frames to modify the In and Out of the render range for
previews and caching.
The Render Start and Render End time fields.
The Current Time Field
The Current Time field at the right of the transport controls displays the frame number for the
playhead position, which corresponds to the frame seen in the viewer. However, you can also
enter time values into this field to move the playhead by specific amounts.
When setting ranges and entering frame numbers to move to a specific frame, numbers can be
entered in sub-frame increments. You can set a range to be –145.6 to 451.75 or set the playhead
to 115.22. This can be very helpful when animating parameters because you can set keyframes
where they actually need to occur, rather than on a frame boundary, so you get more natural
animation. Having sub-frame time lets you use time remapping nodes or just scale keyframes in
the Spline view and maintain precision.
The Fusion Page Viewer Quality and Proxy Options
Right-clicking anywhere in the transport control area other than over the Play Forward/Play
Reverse buttons lets you turn on and off Fusion quality controls. You can either enable high-
quality playback at the expense of more significant processing times or enter various proxy
modes that temporarily lower the display quality of your composition to speed processing
as you work.
Rendering for final output is always done at the highest quality, regardless of these settings.
High Quality
As you build a composition, often the quality of the displayed image is less important than the
speed at which you can work. The High Quality setting gives you the option to either display
images with faster interactivity or at final render quality. When you turn off High Quality,
complex and time-consuming operations such as area sampling, anti-aliasing, and interpolation
are skipped to render the image to the viewer more quickly. Enabling High Quality forces a
full-quality render to the viewer that’s identical to what is output during final delivery.
