VERA was capable of recording about 15 minutes (e.g. 4,572 meters) of 405-line black-and-white video per reel, and the picture tended to wobble because of some jitter (uneven speed) of the tape transport. Later video recorders used a time base corrector to remove this jitter and make synchronization with the studio house possible.
The quadruplex format employs segmented recording; each transversely recorded video track on a 2-inch quad videotape holds one-sixteenth (NTSC) or one-twentieth (PAL) [6] of a field of interlaced video. (For NTSC systems, the math suggests 15 transverse head passes, each consisting of 16 lines of video, are required to complete one field.)
The first home VCRs to become widely available were the Sony U-Matic system in 1971 and Philips VCR system, released in 1972. However, the first system to be successful with consumers was Sony's Betamax in 1975. This was quickly followed by the competing VHS (Video Home System) format from JVC, and later by Video 2000 from Philips.
Slow-motion sequences could likewise be programmed and could be "triggered" to begin via an external control pulse such as might come from an external VTR editor like the Ampex VR-2000 VTR with Editec. The HS-200 was the first system capable of single-frame video animation recording, using magnetic discs as opposed to videotape.
