I am fairly new to the editing and YouTube scene. I finally decided to record and edit a video. Now that I have recorded, edited, and rendered it, it has a bunch of artifacts that I can't seem to get rid of. I spent hours on the footage and it took 2 hours for it to render. Here is a example clip from my edit. I double checked to see if my recording software was the culprit. It wasn't, it was HitFilm. Help is appreciated.
