What resolution is associated with High Definition (HD) cameras?

High Definition (HD) encompasses a variety of resolutions, and all the options listed are recognized as HD formats.

720p, which has a resolution of 1280x720, is often referred to as "HD ready." This format offers a significant improvement in quality compared to standard definition, making it widely used for television broadcasts and online streaming.

1080i and 1080p both refer to Full High Definition (Full HD) and have the same resolution of 1920x1080. The key difference lies in their methods of displaying the video. 1080i is interlaced, meaning the image is composed of alternating lines, while 1080p is progressive scan, displaying all lines in each frame, resulting in smoother motion and clearer images, particularly useful for fast-moving content.

Since each of these resolutions falls under the HD category, stating that all of the provided resolutions are associated with HD cameras is correct.
