Action

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

Extrapolation

Action to take for gaps past the strip extents.

Hold

Affects both sides of the strip. This should only be set on the very first strip.

Hold Forward

Affects the region after the clip, only. This can be set on any strip.

Nothing

Affects only the region of the strip itself. This can be set on any strip.

Blending

Affects how the property values directly produced by the strip are combined with the result of evaluating the stack below. The bottom-most strip is blended on top of the default values of the properties.

Replace

The top strip is linearly blended in with the accumulated result according to influence, completely overwriting it if influence is set to 100%.

Multiply, Subtract, Add

The result of the strip is multiplied, subtracted, or added to the accumulated results, and then blended in according to influence.

\(result = mix(previous, previous (+-*) value, influence)\)

Combine

Depending on the type of each property, one of the following methods is automatically chosen:

Axis/Angle Rotation

\(result = previous + value * influence\)

This results in averaging the axis and adding the amount of rotation.

Quaternion Rotation

Quaternion math is applied to all four channels of the property at once:

\(result = {previous} \times {value} ^ {influence}\)

Proportional (Scale)

\(result = previous * (value / default) ^ {influence}\)

Others

\(result = previous + (value - default) * {influence}\)

This allows layering actions that can also be used as a standalone. Properties keyframed at their default values remain at default.

Nota

Since this blending mode is based on using quaternion multiplication to calculate the Quaternion Rotation properties, it always drives all four channels during playback, and Insert Single Keyframe is forced to insert all four keys. Other types of channels can still be keyed individually.

Influence

Amount the active Action contributes to the result of the NLA stack.

Strip

Name

Name of the track which the strip currently belongs to.

Mute

Toggles NLA strip evaluation, the strip outline will be dashed.

Active Strip

Reference

Panel

Sidebar ‣ Strip ‣ Active Strip

Active Strip panel.

Frame Start/End

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 Extrapolation.

Blending

See Blending.

Blend In

Set the frame that represents when this strip will have full influence.

Out

Set the last frame of this strip’s full influence.

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.

Reversed

Cause this strip to be played completely backwards.

Cyclic Strip Time

Cycle the animated time within the action start and end.

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 Time

Same as Animated Influence, but with Strip Time.

Action Clip

Reference

Panel

Sidebar region ‣ Animations ‣ Active Clip

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.

Frame Start/End

How much of the Action to use.

For instance, it is common to set the first and last keyframe of an Action to be the same keyframes. The problem with this is if you loop the animation, there is a slight hitch where the same keyframes are played twice. To fix this, simply reduce the End Frame.

Nota

If you select values that are above or below the actual keyframe count of the Action, then the F-curve Extrapolation will be applied.

Sync Length

Causes the Start and End Frames, above, to be reset to the first and last keyframed frames of the Action.

Now

Causes the Start and End Frames, above, to be reset to the first and last keyframed frames of the Action.

Playback 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.

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