User Manual

bandwidth, interactive render times, and memory usage.The proxy clip must have the same
number of frames as the source clip, and the sequence numbers for the clip must start and end
on the same frame numbers. It is strongly suggested that the proxies are the same format as
the main files. In the case of formats with options, such as Cineon, DPX, and OpenEXR, the
proxies use the same format options as the primary.
Trim
The Trim range control is used to trim frames from the start or end of a clip. Adjustthe Trim In to
remove frames from the start and adjust Trim Out to specify the last frame of the clip. The
values used here are offsets. A value of 5 in Trim In would use the fifthframe in the sequence
as the start, ignoring the first four frames. A value of 95would stop loading frames
after the 95th.
Hold First Frame/Hold Last Frame:
The Hold First Frame and Hold Last Frame controls hold the first or last frame of the clip for the
specified amount of frames. Held frames are included in a loop if the footage is looped.
Reverse
Select this checkbox to reverse the footage so that the last frame is played first, and the first
frame is played last.
Loop
Select this checkbox to loop the footage until the end of the project. Any lengthening of the clip
using Hold First/Last Frame or shortening using Trim In/Out is included in the looped clip.
Missing Frames
The Missing Frames menu determines the Loader behavior when a frame is missing or is unable
to load for any reason.
 Fail: The Loader does not output any image unless a frame becomes available.
Rendering is aborted.
 Hold Previous Output: The last valid frame is held until a frame becomes available
again. This fails if no valid frame has been seen—for example, if the first frame is
missing.
 Output Black: Outputs a black frame until a valid frame becomes available again.
 Wait: Fusion waits for the frame to become available, checking every few seconds. This
is useful for rendering a composition simultaneously with a 3D render. All rendering
ceases until the frame appears.
The Magic Comp Variable
Loaders and Savers use the absolute file paths for the location of media. However, if
you are using Fusion Studio, you can use a file path that is relative to the saved
composition location. The Comp variable works for Loaders and Savers and helps you
to keep your work organized. Entering Comp:\ in place of the full file path name is a
shortcut for the folder where your Fusion composition document is saved.
You can either enter the Comp:\ manually into the filename field of a Loader, or turn on
the Enable Reverse Mapping of Paths Preferences checkbox in the Path Map
preferences. Enabling the Path Map preference check box will use the Comp:\
automatically.
