When using clip history
in an Autodesk Visual Effects and Finishing product, the following
limitations apply:
If you expand a clip with an Action module
or node in Smoke, only features that are already available in Smoke
are editable. If the clip is reopened in Inferno, Flame, or Flint,
the features accessible in these products will be retained.
If you have a Paint or Stabilizer element
in your clip history, all modules that precede the Paint or Stabilizer
module will not be editable. You can, however, modify the elements
before the Paint or Stabilizer element by selecting the element
immediately preceding the Paint or Stabilizer element in the history,
and then pressing the Match hotkey
to create a clip with the same history in the Source Area. You can
then use the result clip from the match. The history is expandable
and editable.
The duration of a clip created in the
Paint module is not retained. For example, enter the Paint module
with None selected, and then in the Paint module create a scene
that is 30 frames. Then go into a module such as Action and
make some changes. When you view the clip history and click the
Paint module element, the clip will contain one frame only.
When you enter a module from clip history,
in and out points mark the duration in the source clip that was
used in the clip history (unless the entire clip was used). If you
then make a modification and process the result, only the duration
of the clip marked by in and out points is rendered, unless you
park the cursor before the in point. If the cursor is parked before
the in point, media is added to the head frames, starting from the
cursor position.
Always apply soft effects or Batch FX
after you work in modules if you want to edit the soft effects from
the clip history. If you process a clip in a module after a soft
effect has been added to the clip history, you can no longer modify
the preceding clip history. The clip name is also greyed out to
indicate that the preceding soft effects and modules are no longer
editable. For example, if you add a timewarp to a clip and then
go into the Colour Corrector module and process the clip, you will
not be able to edit the timewarp in the History view. The timewarp
will be greyed out in the clip history.
When you process a clip or element starting
at a frame other than the first, the leading unprocessed frames
are padded with unrendered frames. Unrendered frames are put in
the header of the clip, producing a soft clip with a specific number
of heads. This is necessary in Inferno, Flame, and Flint so that
when you expand clip history in Batch, the frame numbers match between
all nodes in the Batch schematic. It is also necessary in Smoke
so that you can trim the element and then access the clip history
to render the missing media.
