When comparing the contours of the background fluorescent light, the difference in image quality is clear, and it seems that there is not much difference between HD 720p and 1080p, but the difference between DVD and HD 720p is remarkable.

Also, although Xvid has the lowest image quality, considering that this is a movie compressed to a size of one CD (700 MB), if you use just the same capacity as DVD, I wonder if it will go up.

By the way, it is about 576p for DVD, 720p for HD, 1080p, but it seems to refer to the number of lines on the screen (number of vertical pixels). In the case of HD 720p, the screen size is 1280 × 720, and for 1080p it will be 1920 × 1080. Details of the links are detailed below.
