>>4135785The word you're looking for is bokeh. You need a real camera with an f/2.0 lens or so, about $200 in lighting gear, and at least some sort of audio recording system to get the 'pro look'. Prepare to spend a shocking amount of time learning how to edit and editing footage.
I think mine is probably the cheapest option out there, and it's about $450 for the camera & lens. This is an EOS M200 with the 22mm f/2.0 lens.
I bought this for making videos, along with a $130 HDMI capture card for unlimited recording time back in late 2021. I haven't made a single video yet.
It's harder than it looks, and you'll probably waste your money like I did. :)
