SVHS arrived sometime {{unsure|around 1994}} with the purchase of an SVHS Camcorder (a [[Panasonic MS4]]) and a recorder/player to go in the control room. Most things had to be dubbed to U-Matic for editing until the availability of the [[The Mac|Media100 computer edit suite]] in 1998. | SVHS arrived sometime {{unsure|around 1994}} with the purchase of an SVHS Camcorder (a [[Panasonic MS4]]) and a recorder/player to go in the control room.

A higher quality version of VHS, both in terms of number of lines and recording luma and chroma seperately, it later replaced Umatic for editing (around 2000, although further displaced by computer edit suites by 2003). It continues as a live program capture format, although now secondary to digital capture for repeats and archiving. Some outside broadcasts still rely on SVHS as the primary recording format, with digital copies being produced from the SVHS tape. | A higher quality version of VHS, both in terms of number of lines and recording luma and chroma seperately, it later replaced Umatic for editing (around 2000, although further displaced by computer edit suites by 2003).

=== XviD === | |||
Derived from the MPEG-4 reference code, this is an open source lossy video codec from [http://www.xvid.org/ xvid.org]. It was first used to encode DV video uploaded to the [[Video Server]] to economise on disk space. As this usage increased to include all video played out from the Video Server, it became useful to archive the files even after they were deleted from the system, to avoid time consuming capture from tape. As Premiere Pro will import compressed video files, it is now much more convenient to find clips from the digital archive on data DVDs than from SVHS tapes, so XviD compressed files have become the dominant format for archiving final productions. | |||

This is found both as MiniDV format tape cassettes, and as DV data burnt to data DVDs. The latter are usually items from edit sessions that are likely to be needed again for editing in the future, so the quality loss of compressing and decompressing a more compressed format is undesirable. MiniDV is universal for outside filming, although direct capture of DV data to computer has replaced it for most studio work. | This is found both as MiniDV format tape cassettes, and as DV data burnt to data DVDs.

YSTV used HDV from 2008 for use in the HVR-HD1000E cameras. | |||

YSTV uses this for recording onto the video server, It's literally the bitstream as it comes from the capture cards. | |||
