I use both the base M4 Mac mini and an M4 MacBook Air for Final Cut Pro, Photoshop, and Fusion, and while they're not as almost-always-perfectly-smooth as my Mac Studio, they're about 100x better than the experience I used to have on my old Intel MacBook Pros in the 2010s.

I edit 4K ProRes and H.265 footage, sometimes with multicam (up to 4 streams) and color adjustments, titles, etc. It's only after stacking 3-5 effects before things can stutter, really.

Or if you try doing something CPU-intense in the background _while_ running some heavy creative software. I just don't do that.
