basically i made a script to reproduce this effect with blender:
im a fan of this piece of art. It was made in 1968 by norman mclaren, with an opticalprinter. Which is the same as saying that he did it by hand.
here is the addon:
Select a movie or meta strip, set number of echoes and offset (in frames), and press Eco button.
The opacity of all strips is updated to 1/number of echoes to mantain luminance. The blending is set to add for all clips except first one.
All clips are grouped inside a meta. Press home after running the script to see the meta.
here is a video made mainly with this script.
i want to add settings to choose blend options and opacity settings.
if you want to play with settings you can edit lines 145 and 146
active_strip.blend_type = 'ALPHA_OVER' active_strip.blend_alpha = 1/eco
where eco is the number of echoes.
if trying to emulate mclaren, use this settings (only with low-low key images)
active_strip.blend_type = ‘ADD’
active_strip.blend_alpha = 1
hope you enjoy it,
and watch your memory limits
