Now there is a hope an a half

I have broken my procedure into sections, makes it easier to follow, however the end result is a 1.2 second video (meant as a transition)
Half size version looks like this:  https://i.imgur.com/ChyQ7tO.mp4

1. Scale the image to 50 layers using the gimp_gmic_qt plugin. Get the plugin from http://www.gmic.eu

2. Merge the 50 layer (scaled) layers with a 50 layer animation. You have to get the animation from somewhere. The merge uses Ofnuts ofn-interleave-layers.py python plugin
see: http://sourceforge.net/projects/gimp-too...es/scripts  ofn-interleave-layers.zip dated 2020-04-25  Unzip read the help notes. The plugin goes in your plug-ins folder.

3. Exporting the 50 layers to individual files to render into a video. Many video editors will take a sequence of numbered files, Avidemux does and the one shown in the video Openshot. I normally use command line FFmpeg but the particular command is no good in Windows.
Exporting the layers uses a script  export-layers-plus.scm  Zipped and attached. Unzip and put in your Gimp scripts folder.

So once again thanks to both of you guys!

LOL. I was expecting to see a lot of things, but not that for sure. Electric boogaloo as they say.

I had to update my Gimp from 2.10.8 to 2.10.30 for the plug-in to work.

Afterwards for some reason my PC really struggled to make the 50 crab layers - it took over 2 minutes while for you it looked like it was instantaneous.

Thank you for explaining the shift click layer. That's easy to remember and I can see it being useful in the future.

After some struggling I've finally managed to get this plugin working! (Well, at least it shows up!) So that's where I'll leave it for today.

There must be some easy way to just copy a still image for all 50 layers right?
