Replying to Help me with my editing ( +k)

Okay so i film with a old ass sony cam that has pretty good quality, i know when i capture it it loses alot but i dont understand why this comes out so shitty, It lags alot and quality is borderline terrible. Is their anyway to render it so it comes out nicer or is it just the camera and theres no way around this laggy and shit quality work.

By the way this is on the help of my edit not saying we suck yeah were not too good but we have fun and itss like our 1st/ 2nd yr in freestyle so .. Help not hate
