Properties & Modifiers

Properties

Strip properties can be accessed via the NLA Properties region.

Animation Data

Reference

Panel:Properties region ‣ Animations ‣ Animation Data
../../_images/editors_nla_properties-modifiers_animation-data-panel.png

Animation Data panel.

Action
A Data-Block menu that allows you to edit actions shown in the action track. See also the Action Editor’s Action.
Action Extrapolation

Action to take for gaps past the strip extents.

Hold
Affects both sides of the strip.
Hold Forward
Affects the region after the clip, only.
Nothing
Neither.
Action Blending

Affects the behavior when two tracks simultaneously have a curve affecting the same property.

Replace
Causes the top strip to take precedence according to the parameters of the Blend In/Out (see next option, below).
Multiply, Subtract, Add
The weighted result of the strip is multiplied, subtracted, or added with the accumulated results.
Action Influence
Amount the active Action contributes to the result of the NLA stack.

Active Track

Reference

Panel:Properties region ‣ Animations ‣ Active Track
Name
Name of the track which the strip currently belongs to.

Active Strip

../../_images/editors_nla_properties-modifiers_active-strip-panel.png

Active Strip panel.

Options of the strip itself.

Name
Renames the strips.
Type
Will either say “Action Clip”, “Transition”, or “Meta”, according to the three types of strips.
Strip Extents
The boundaries of the strip itself. Note that this will stretch the duration of the Action, it will not cause greater or fewer keyframes from the Actions to play (see below for that option).
Extrapolation
See Action Extrapolation above.
Blending
See Action Blending above.
Auto Blend In/Out
Creates a ramp starting at the overlap of the strips. The first strip has full control, and it ramps linearly giving the second strip full control by the end of the overlapping time period.
Blend In
Set the frame that represents when this strip will have full influence.
Blend Out
Set the last frame of this strip’s full influence.
Muted
Mute a single strip (like muting the track, above). Causes the track outline to be dashed.
Reversed
Cause this strip to be played completely backwards.

Action Clip

Reference

Panel:Properties region ‣ Animations ‣ Active Clip
../../_images/editors_nla_properties-modifiers_action-clip-panel.png

Action Clip panel.

This represents the ‘object data’ of the strip. Much like the transform values of an object.

Action
A reference to the Action contained within the strip. Can be changed to replace the current strip’s value with another Action.
Action Extents

How much of the Action to use.

Note: If you select values that are above or below the actual keyframe count of the Action, then the F-Curve Extrapolation will be consulted. Which can be changed in the Graph Editor, under Channel ‣ Extrapolation Mode.

Sync Length
Causes the “Start” and “End” Frames, above, to be reset to the first and last keyframed frames of the Action.
Sync Action Length “Now”
Causes the “Start” and “End” Frames, above, to be reset to the first and last keyframed frames of the Action.
Playback Settings
Scale
Stretches strip, another way of increasing the Strip Extents: End Frame, above.
Repeat
Also expands the strip, but by looping from the first keyframe and going forward.

Evaluation

Reference

Panel:Properties region ‣ Animations ‣ Evaluation
../../_images/editors_nla_properties-modifiers_evaluation-panel.png

Evaluation panel.

This determines the degree of influence the strip has, and over what time.

Animated Influence

Enabling alteration of the degree of influence this strip has as a keyframable value. If influence isn’t animated, the strips will fade linearly, during the overlap.

These can be found in the Dope Sheet or Graph Editors under the NLA Control Curves and look like group channels. They appear before all the groups/F-curves for that channel.

Animated Strip
Same as Animated Influence, but with Strip Time.
Cyclic Strip Time
Cycle the animated time within the action start and end.

Modifiers

Reference

Panel:Properties region ‣ Modifiers ‣ Modifiers

Like its counterparts in graph and video editing, Modifiers can stack different combinations of effects for strips.

See F-Curve Modifiers.
