The terms "hdrip" and "720p" refer to the quality of the video. "HDrip" indicates that the video is a rip from a high-definition source, suggesting that it is of a higher quality than standard definition content. "720p" specifically denotes a resolution of 1280x720 pixels, which is a common benchmark for high-definition video. The inclusion of "mp4" indicates that the video is encoded in MPEG-4 Part 14, a widely used format for digital video.
