Excessive Compression on Animated Maps

Hi, so for the past week or so I've been working on 3d modeling an animated map for an upcoming session that I'm planning on running. I got it all working, exported as both an mp4 and a webm just to be safe. Both are well under the 10mb limit (the mp4 is 4mb while the webm is under 1mb.) I have the images of before and after compression below. It appears even worse when animated, leaving artifacts behind on every frame, it almost looks scaled down to like, 480p sometimes. I've tried this with multiple file formats, and had multiple players look at it on a variety of hardware. I've tried different browsers and they all have this issue. Is there any way to fix this?

You haven't tried uploading them yet, have you? It will likely take a couple hours of uploading per try, and if it fails, it will fail silently. If you can isolate the animated components, you would possibly be better served by animating only those portions and dropping them over a still image for the bulk of the map.

Actually, I have uploaded them, multiple times in fact, and the upload only ever takes around 10 minutes or so, though checking back in today on that map that I've let sit overnight, the problem still persists.  The issue is, I'm a sucker for lighting and kind of nitpicky about it. If it were just animated components, that'd be one thing, but I wanted things to actually reflect the lighting and react to it changing. There's a big portal that's at the bottom of the screen that casts a shifting light across most of the scene and it's a bit hard to just isolate that.
