Most of today’s digital cameras include functionality for recording digital video. Today’s high-end DSLR cameras, with their relatively small size, high quality interchangeable lenses, and highly adjustable shooting modes, have become the de-facto entry point for high quality videography. DSLR video is even being used for television and movie production.
Digital video currently comes in two main resolutions (with a third, higher resolution, becoming more mainstream): standard definition, and high definition (HD). Standard definition is usually considered to be any resolution with a vertical height of less than 720 pixels (abbreviated to 720p), and high definition is 720p and above. 1080p is considered “Full HD”, and is the most prevalent resolution for today’s flat panel televisions, and most television broadcasts are now in the same resolution.
Higher resolutions are becoming more prevalent in both monitors and television sets, as well as recording equipment. Ultra High Definition (UHD) resolutions typically start at 2160 vertical pixels and above, which, when combined with width, has four times as many pixels as Full HD.
The frame rate of digital video is the number of frames in one second of footage. The frame rate of video plays an important part of how video looks. Whereas many digital video recording devices record at 30fps or higher, movies are almost always filmed at 24 frames, which gives it a “cinematic” appearance. Very high frame rates usually creates video that appears artificial, sometimes called the “soap opera effect”.
