In this video tutorial, the presenter discusses various video formats and their evolution up to March 2019. Historically, home consumer visual formats were relatively straightforward, with early TVs displaying a smaller rectangular picture at a resolution of 480. The video explains terms like 480p and 1080i, where "p" denotes progressive scanning and "i" indicates interlaced scanning. Interlaced scanning draws the image by displaying odd lines first and then even lines, a carryover from older technology. This method can lead to flicker, as the human eye can perceive the way the image is painted line by line due to low resolutions.
