The camera isn't the problem
You wrote the script, learned it well, and stood in front of the camera. On the first take you forgot a line. On the second you said it in the wrong order. The third one was right, except your eyes drifted to the paper at the end.
An hour later you have twenty attempts, a tired voice, and less than a minute of usable video. Then in the edit you find that your best line is the one where you weren't looking at the lens.
Most creators know this day well. Memorizing drains you, and a sheet of paper next to the camera shows up in your eyes however hard you try.
