While I was looking at the project.json, I saw something that said “bitmap resolution”. What is this?

Scratch usually scales images to twice the original size so they look better when you press fullscreen. To save some processing time (at the cost of filesize), Scratch saves this enlarged image rather than the original. If bitmap resolution is 2, that means the saved image is twice the size of the rendered image in Scratch. If bitmap resolution is 1, that means it is the same as when viewed in Scratch.

Scratch doesn't always upscale images, if I remember correctly. If you upload a 960x720 image, the image in Scratch will be 480x360 while the saved image will stay the same (bitmap resolution = 2). It is mainly when you draw an image in the editor that it is upscaled. If you have heard of half-pixels that's what they are talking about.

Mildly confused here. If I uploaded a 15360×8640 image it'd be optimised to 480x360? (8640p -> 480p)

It would be downscaled to 960x720.
