Hey Austin, great work on this video! I can tell you put a lot of thought into your videos, including your set, audio and video equipment, content planning etc, thumbnail, your editing is very smooth, etc. nice work!
As far as areas of improvement, I watched to about the 4 minute mark to get enough of the pacing to leave some qualified notes. I've seen plenty of youtube videos on this topic of mac performance issues and solutions, and I would say this video could be tightened up to about 8 minutes. As somebody who has needed these videos from time to time, I can say from experience that I'm usually already frustrated because of how much time I've lost due to computer performance issues, so the biggest thing I look for in a video like this, is how much more of my time do I need to trade for the information I need. Specifically, you could cut a lot of the talking portions where you're educating the viewer, but not doing anything on the computer. Most ppl like me just want the solution, not the education.
One other thing I thought of that might add to the anticipation of what tips are coming, is to have the number of tips in your title, then have a running list that reveals the next tip one at a time, but the numbered list appears each time, so each time a new tip is shown, the viewer has FOMO to leave before the rest of the un revealed tips are shown.
Keep up the great work Austin!
