A question about video editing apps

Glad OP brought this up! If you use something like OBS to film in game, will that help with your FPS? Or No? I did a short little you tube video of my Sim dancing, although I think it's cute my Son thought it looked laggy or whatever, and I feel like that is due to low FPS, but I am no expert at all but would love to start doing some short videos for my you tube..wondering would OBS help?
