Trying to Do Batch/Script Work on Combining Multiple Images.

[rich2005]

I see you need a separate defect frame applied to each video frame. Ofnuts script can do that with that small modification for the new Gimp 2.10 layer modes. However. 400 frames = 400 HD layers = 2 GB in memory. One of those for each set and interleaved creates a third file 2 GB in memory. That is a lot of resources.

You could ask for help to create a bespoke script to run in batch mode.You might get a response.

Another way is using ImageMagick (IM) http://www.imagemagick.org where the compose operation also has the equivalent (hopefully ) lighting composition methods. All command line see http://www.imagemagick.org/Usage/compose/

A pair of images combine with a command 

Code:

magick composite -compose vivid_light  orig.jpg defect.jpg  new.png

You would need to put that into a Windows batch file. Sorry but using linux here , my Windows batch scripting is even flakier than my linux scripting I pulled those 400 frames, with watermarks / text etc out of your video and using vivid light as a demo this:

If you want to pursue that then the best place to ask is https://www.imagemagick.org/discourse-server/ in the users section. There is a Windows user there who is very helpful.
