DVCAM

It is about the “professional” version of the DIGITAL Video of the firm Sony. DVCAM positions, today, more in the institutional sector that professional. Indeed, such a narrow band (1/4") is not adapted to the difficult conditions of turning like to the intensive requests in assembly.

Video

The DVCAM remains in conformity with the specifications of FD as for the distinction made for the two systems of sweeping, namely in 525 lines and 625 lines. The compression of factor 5 is always carried out of intra-screen or intra-image (M-JPEG). The principal point which differentiates the DVCAM from the FD large-public lies in the tape speed linear of the band which was increased in the DVCAM to carry the width of the tracks to 15 µm instead of 10 µm. This to increase the reliability of the recording. And the recording of 4 sound tracks with 32 Khz or two tracks 48 Khz against two tracks 32 Khz out of mini-FD. All the remainder is identical.

Cassettes

They are proposed in two sizes which are the same ones as out of FD. The small one (S) which offers durations of 12,22,32 and 40 minutes, and the large one (L) which makes it possible to reach the 64,94,124 and 184 minutes. The format is also present in the new technology of Professional Disc from Sony. This disc of 24g, protected by a case, uses the blue ray for encrypter its data on this support.
