The first such device, the Betamovie BMC-100/110, was released in 1983 by Sony. Although the term was not in common use at that time, such a device would later become known as a camcorder, a single unit comprising a video camera and a video recorder. The BMC-100/110 weighed just 2.5 kg and was a much less cumbersome solution than its predecessors.
All of the above cameras record 1920x1080 video at 60i/30p (NTSC regions) or 50i/25p (PAL regions), in MPEG-4, AVCHD or H.264 formats. The Alpha 65 and 77 also records video at 50p or 60p, and the Alpha 99II records 4k video at 100 Mbit/s (using XAVC S) with full sensor read-out.

Betamax records relatively low-resolution video using a heterodyne color recording system and only two recording heads, while Betacam uses four heads to record in component format, at a much higher linear tape speed of 10.15 cm/s (3.99606 in./s) compared with Betamax's 1.87 cm/s (0.7362205 in./s), resulting in much higher video and audio quality.
DV (from Digital Video) is a family of codecs and tape formats used for storing digital video, launched in 1995 by a consortium of video camera manufacturers led by Sony and Panasonic. It includes the recording or cassette formats DV, MiniDV, HDV , DVCAM, DVCPro, DVCPro50, DVCProHD, Digital8 , and Digital-S .
D-1 or 4:2:2 D-1 (1986) was a major feat in real time, broadcast quality digital video recording. It stores uncompressed digitized component video, encoded at Y'CbCr 4:2:2 using the CCIR 601 raster format with 8 bits, [1] [2] along with PCM audio tracks as well as timecode on a 3/4 inch (19 mm) videocassette tape (though not to be confused with the ubiquitous 3/4-inch U-Matic/U-Matic SP cassette).
Video quality is a characteristic of a video passed through a video transmission or processing system that describes perceived video degradation (typically compared to the original video). Video processing systems may introduce some amount of distortion or artifacts in the video signal that negatively impact the user's perception of the system.
