if i were to record 5 - 10 hours of screen recording how much memory would it take up?

i just wanted to know since i wanna record myself painting on clip studio paint. i have a mac mini late 2014. i have a 1.4 GHz Intel Core i5 processor. 352.12 GB free of 498.89 GB.

This would vary with the clocking of your system for the particular CPU configuration, number of processes active during the period of the recording, and the resolution of the recording. You will likely have to run your own computations under actual test conditions for best approximations. On my I7 system, a 1440p9.19 (2560x1440 @ 9.19fps) recording requires a data bandwidth on the order of 81 MB/sec or something under 5 GBs/hr or 25 GBs (5 hour recording) to 50 GBs (10 hour recording) whether recorded in a single or multiple segments.
