Looping over a JSON to crop an image sequence

So, I have an image sequence that I’ve saved out of After Effects that I need to crop in various ways.

I have have defined the crop areas (along with filename prefixes) in a JSON (could be a different format).

The idea is to loop over every defined crop area in my JSON, cropping all of the images in the sequence, and then saving a new copy by prepending the filename prefix to each.

Is this something Retrobatch can handle?

In theory I think this could be done.

Can you provide some sample images as well as the JSON files (you can send them to support@flyingmeat.com ). I’m kind of curious if I can make it happen with a JS node.
