Keyframe
(bpy_struct)¶ Bezier curve point with two handles defining a Keyframe on an F-Curve
-
amplitude
¶ Amount to boost elastic bounces for ‘elastic’ easing
Type: float in [0, inf], default 0.0
-
back
¶ Amount of overshoot for ‘back’ easing
Type: float in [-inf, inf], default 0.0
-
co
¶ Coordinates of the control point
Type: float array of 2 items in [-inf, inf], default (0.0, 0.0)
-
easing
¶ Which ends of the segment between this and the next keyframe easing interpolation is applied to
AUTO
Automatic Easing, Easing type is chosen automatically based on what the type of interpolation used (e.g. ‘Ease In’ for transitional types, and ‘Ease Out’ for dynamic effects).EASE_IN
Ease In, Only on the end closest to the next keyframe.EASE_OUT
Ease Out, Only on the end closest to the first keyframe.EASE_IN_OUT
Ease In and Out, Segment between both keyframes.
Type: enum in [‘AUTO’, ‘EASE_IN’, ‘EASE_OUT’, ‘EASE_IN_OUT’], default ‘AUTO’
-
handle_left
¶ Coordinates of the left handle (before the control point)
Type: float array of 2 items in [-inf, inf], default (0.0, 0.0)
-
handle_left_type
¶ Handle types
FREE
Free.VECTOR
Vector.ALIGNED
Aligned.AUTO
Automatic.AUTO_CLAMPED
Auto Clamped, Auto handles clamped to not overshoot.
Type: enum in [‘FREE’, ‘VECTOR’, ‘ALIGNED’, ‘AUTO’, ‘AUTO_CLAMPED’], default ‘FREE’
-
handle_right
¶ Coordinates of the right handle (after the control point)
Type: float array of 2 items in [-inf, inf], default (0.0, 0.0)
-
handle_right_type
¶ Handle types
FREE
Free.VECTOR
Vector.ALIGNED
Aligned.AUTO
Automatic.AUTO_CLAMPED
Auto Clamped, Auto handles clamped to not overshoot.
Type: enum in [‘FREE’, ‘VECTOR’, ‘ALIGNED’, ‘AUTO’, ‘AUTO_CLAMPED’], default ‘FREE’
-
interpolation
¶ Interpolation method to use for segment of the F-Curve from this Keyframe until the next Keyframe
CONSTANT
Constant, No interpolation, value of A gets held until B is encountered.LINEAR
Linear, Straight-line interpolation between A and B (i.e. no ease in/out).BEZIER
Bezier, Smooth interpolation between A and B, with some control over curve shape.SINE
Sinusoidal, Sinusoidal easing (weakest, almost linear but with a slight curvature).QUAD
Quadratic, Quadratic easing.CUBIC
Cubic, Cubic easing.QUART
Quartic, Quartic easing.QUINT
Quintic, Quintic easing.EXPO
Exponential, Exponential easing (dramatic).CIRC
Circular, Circular easing (strongest and most dynamic).BACK
Back, Cubic easing with overshoot and settle.BOUNCE
Bounce, Exponentially decaying parabolic bounce, like when objects collide.ELASTIC
Elastic, Exponentially decaying sine wave, like an elastic band.
Type: enum in [‘CONSTANT’, ‘LINEAR’, ‘BEZIER’, ‘SINE’, ‘QUAD’, ‘CUBIC’, ‘QUART’, ‘QUINT’, ‘EXPO’, ‘CIRC’, ‘BACK’, ‘BOUNCE’, ‘ELASTIC’], default ‘CONSTANT’
-
period
¶ Time between bounces for elastic easing
Type: float in [-inf, inf], default 0.0
-
select_control_point
¶ Control point selection status
Type: boolean, default False
-
select_left_handle
¶ Left handle selection status
Type: boolean, default False
-
select_right_handle
¶ Right handle selection status
Type: boolean, default False
-
type
¶ Type of keyframe (for visual purposes only)
KEYFRAME
Keyframe, Normal keyframe - e.g. for key poses.BREAKDOWN
Breakdown, A breakdown pose - e.g. for transitions between key poses.MOVING_HOLD
Moving Hold, A keyframe that is part of a moving hold.EXTREME
Extreme, An ‘extreme’ pose, or some other purpose as needed.JITTER
Jitter, A filler or baked keyframe for keying on ones, or some other purpose as needed.
Type: enum in [‘KEYFRAME’, ‘BREAKDOWN’, ‘MOVING_HOLD’, ‘EXTREME’, ‘JITTER’], default ‘KEYFRAME’
