In November 2012, VITEC began shipping the FS-T2001 Portable Recorder, which uses Sony XDCAM HD422 and XDCAM HD codec.
The XDCAM format uses multiple video compression methods and media container formats.
This format employs MPEG-4 video encoding at 1.5 Mbit/s (CIF resolution) with 64 kbit/s (8 k Hz A-law, ISDN-quality) for each audio channel.
The Professional Disc was chosen by Sony as its medium for professional non-linear video acquisition for a number of reasons, outlined in their white-paper Why Sony Adopted Professional Disc.
This format supports multiple frame sizes, frame rates, scanning types and quality modes.
Depending on product line or a particular model, not all modes of this format may be available.
In September 2008, JVC announced its alliance with Sony to support the XDCAM EX format.
In August 2009, Convergent Design began shipping the nano Flash Portable Recorder, which uses the Sony XDCAM HD422 codec.
To accommodate the improved chroma detail, video bitrate has been increased to 50 Mbit/s. Proxy AV is used to record low resolution proxy videos.
This disc is similar to Blu-ray Disc and holds either 23 GB of data (PFD23, single-layer, rewritable), 50 GB (PFD50, dual-layer, rewritable), 100 GB (PFD100TLA, triple-layer, rewritable) or 128 GB (PFD128QLW, quad-layer, write-once).
Essentially, the Professional Disc format was deemed to be a suitable, cost effective and easy step forward.
The first camera to use this media was the Sony PMW-EX1 professional video camera.
In December 2009, Sony introduced the more affordable Sx S-1.
