Betacam SX is a digital version of Betacam SP. Launched in 1996, Betacam SX served as a transitional format which was cheaper than Digital Betacam. It also had the advantage of being compatible with Betacam SP tapes.
Betacam SX uses MPEG 4:2:2 compression with 4 channels of 48 KHz 16-bit PCM audio.
Betacam SX cassettes come in the same S and L sizes as other Beta formats, coloured yellow. S tapes have a recording time of approximately 60 minutes; L tapes record up to 194 minutes.
