What The Camera Captures

Back camera offers more precision than front camera, but in the case of the former, I can't see what is being captured as it is being captured, and that's why I was utterly disappointed how the original video, from which I made the promo video for my fourth book https://www.youtube.com/watch?v=pfYmnYXVa1Y, turned out.

The screenshot here was taken from a video taken AFTER that video.
