Hey thanks for saying that, appreciate it!
I actually do everything with Stop Motion Studio & CapCut. The light, shadows, and flickering are certainly some of the first challenges. Recommend avoiding natural light and only use one light source. Also make sure to lock your exposure and white balance in stop motion studio. After exporting your video, clean it up in CapCut, using the stabilize video tool, then add whatever effects and filters you want.
You don't need much to get going, or a studio. A table, a tripod and a single ring light is all I use for the majority of my stop motion content. I tape the baseplate down to the desk to further stabilize things. Here's a quick shot of what it looks like.
