Please Help

I want to record Valorant highlight for content put into insta/tiktok.
What is best software to record highlights. it is good it's only records highlights because I don't have much time to edit because I'm working.

It need to work well in my mid pc. Thanks!

Obs has a replay capture system if you do some research and it's super light on your PC iirc. I haven't used it in years tho
