As reported previously in the Pro Apps Hub, JVC’s ProHD strategy is a marketing catch-all for all their HD offerings based on MPEG-2 transport streams. Included in the stragegy is the HDV KY-HD100U and the HDV+ GY-HD7000U.
Available in “early summer” the KY-HD100 is a professional-level HDV camcorder with solid camera-operator-friendly features that justify the ProHD moniker. Three 1/3″ CCDs sit behind a removable lens, although standard is a Fujinon 16x lens developed with JVC. The GY-HD100 records at 30p and 24P at 1280 x 720 resolution in HD and at 29.97 in DV. 24P is accommodated within the 60i standard framework
by repeating a 2:3:3:2 pulldown like the only used by Pansonic in the AG-DVX100using MPEG2 “flags” to flag certain whole frames need to be duplicated, so it does 3 frames and then 2 frames (not fields like the DVX would do) and hence embeds 24p in a 60p video stream, but only records 24p frames of data to tape – quite clever really. This allows JVC to offer 24P even though it was not part of the original HDV specification, without deviating from the specification. [Thanks to Graeme Nattress for the correction.]
See Hub news on March 10 for more details on both cameras. At US$6295 JVC have come in well “under $10,000”.
