I have 7 video frames (saved as PNG) of a lightening strike who's main 'vein' persists over most of the frames but is also producing 'tendrils' that are different in each frame.
I want to make a single image that includes all parts of that strike over time.
I have imported each image in GIMP as a separate layer.
I have tried 'Merge Visible Layers', that basically gives me just the first image.
I have tried setting each image to 50% Opacity and then each image Mode to 'Merge' - which is the closest I can currently get to the desired end-point, unfortunately the grey in the clouds where the image does NOT include the 'tendril' tends to erase that from the image where that tendril IS present.
I have experimented with Add Subtract and Multiply but they all badly effect the overall background image.
I have no doubt that this has been done before, but Google and this forum search does not result in anything awesome.
Attached are a couple of the (reduced to 20%) frames that the effect is visible in.
