You may want to expand a little on what you want.
Do you need peripherals (monitor, keyboard, mouse, speakers/headphones)
Do you have any brand or color preferences? How big do you want the end result to be?
How much storage are you talking about needing for all the video editing.
A good B550 motherboard and a Ryzen 5900X with 32GB of memory would seem to fit the bill comfortably. A modest build around that shouldn't get anywhere near $2500.
I have a founders edtion 3070and what gpu do you have?
