Hi!
Is it possible to add in chdkptp something like "onion skin" for making stop motin movies?
I want to overlay the current live view on a previous frame.
Here's a photo 
Here's a quick hack that might help. Just replace the existing lua/gui_live.lua from chdkptp with the attached.
It adds a new sub-tab where the frame rate and debug tabs are called "onion"
The "grab" button makes a copy of whatever is currently displayed. The grabbed image is blended with the live display, with the amount controlled by the slider. All the way to the left shows only the live image, all the way to the right shows only the grabbed image.
Clear discards the grabbed image completely.
