Compositing question… blending Many Images
I should know how to do this, but I don’t.
I want to blend 25 frames together as 1 frame each image having 4 percent influence on the final image.
If I stack them up as partially transparent layers, the bottom layers will not have enough influence…(totally obscured)
Any Ideas?Thx,

I think (keyword think) if you do two images at a time with a 50% transparency on the top image. Then combine all those comps two at a time. And then combine all those two at a time the end result should be about 5% of each image. I just tested it out and it seems to work well. I’d imagine there’s a better way but I don’t know what it is either.

I think I just realized the answer… put them all to 4 % transparency & put them all to add mode … adding to a black solid.
this way , the final image is the cumulative effect of every image.Peter

You could also create an expression where the opacity is proportional to the position in the layer stack: its index value. Maybe subsitute this for opacity:
index*4
So layer 1 is 4%, layer 2 is 8% … layer 12 is 48% opacity. You could also highlight the 4 and pickwhip it to the value of an expression control (slider) to tweak (or animate!) the opacity factor.
Never tried it …
