TimeEcho

Merges multiple frames from the input into a single frame to create an echo-like effect over time. This allows you to create streaking and smearing effects, for example.

Inputs and Controls

Connection Type	Connection Name	Function
Input	unnamed	The image sequence with the frames to merge.

Control (UI)	Knob (Scripting)	Default Value	Function
TimeEcho Tab
TimeEcho Method	mode	max	Sets how the frames are blended together: • Plus - uses the sum of all frames. Note that this may result in pixel values higher than 1.0. • Max - uses the highest value from the frames. • Average - averages the frames (uses the sum divided by the number of frames). The result is darker than the original images.
Frames to look at	framesbehind	1	Sets the number of frames to merge together, counting backwards from the current frame (and including the current frame). For example, if the current frame is 10, and you set this value to 4, TimeEcho merges frames 7, 8, 9, and 10.
Frames to fade out	framesfade	1	Allows you to fade out frames, so that the further back a frame is in time, the less effect it has on the final images. Note that this is the total number of frames over which the fade happens, with the last of these frames remaining at maximum. For example, if you set this to 5, the fade will gradually happen over the first five frames used, with the fifth frame remaining at maximum: • the first image is reduced to 20% of its original opacity • the second image is reduced to 40% of its original opacity • the third image is reduced to 60% of its original opacity • the fourth image is reduced to 80% of its original opacity • the fifth image remains at 100% of its original opacity.
