"You can only post videos after you have had some regular image contributions."
But what if i'm new 3d artist and want to upload my first video? xD

What's the video about? I'm curious now

It was a measure put in place while ago over shitposting.

I made a Shiver edit and wanted to upload it, and I ran into the same problem, woobomp

Gotta have 5 approved images uploads first. So some nice still images, and once those are approved, THEN you can upload your video. It's a step taken to cut back on trolls and shitposters, savvy?
