description: Blend frames of the input clip.
If a foreground matte is connected, only pixels with a negative or zero foreground value are taken into account, so that the foreground is not mixed with the background.
The number of values used to compute each pixel can be output to the alpha channel.

title: Frame Range
description:
Range of frames which are to be blended together. Frame range is absolute if "absolute" is checked, else relative. The last frame is always included, and then one frame out of frameInterval within this interval.
type: rect
readonly: no
required: no
animation: yes
default: -5 0
title: Absolute
description:
Use an absolute frame range. If the frame range is not animated or is not an expression, then all output images will be the same.
type: boolean
readonly: no
required: no
animation: yes
default: 0
title: Frame Interval
description:
Interval (in frames) between frames to process. 1 means to process every frame in the range. The first frame processed is the lower bound of the range. Can be used to reduce processing time or memory usage.
type: integer

animation: yes
minimum: 1
maximum: 10
default: 1
title: Operation
description:
The operation used to compute the output image.
type: string
readonly: no
required: no
animation: yes
default: Average
values:
title: Decay
description:
Before applying the blending operation, frame t is multiplied by (1-decay)^(last-t).
type: float

title: Output Count to Alpha
description:
Output image count at each pixel to alpha (input must have an alpha channel).
type: boolean
readonly: no
required: no
title: Invert Mask
description:
When checked, the effect is fully applied where the mask is 0.
type: boolean

title: Mix
description:
Mix factor between the original and the transformed image.
type: float

required: no
animation: yes
minimum: 0

default: 1
title: Top-Left Origin
description:
Set to 1 to use MLT top-left image origin instead of the OFX bottom-left origin. Use for plugins that crash or produce incorrect output with negative row bytes.
type: boolean
readonly: no
