Information about Panasonic Ag Hvx200
The Panasonic AG HVX200 is a fixed lens high-definition video camera released in December 2005 (NTSC) and April 2006 (PAL). It can record HD video on solid state P2 cards or record DV video on MiniDV tapes. It also features variable frame rates (used for slow motion & fast motion cinematography) and a recording data rate of up to 100 Mbit/sec, which is four times that of similarly priced HDV and DV cameras. The US$6000 MSRP camera is popular with independent filmmakers.[1]
The camera uses three 1/3 in 960x540 pixel (0.5 mega-pixel) progressive scan CCD's to capture the image. HD resolution is achieved by both horizontal and vertical spatial offset (aka. pixel shift). The green CCD in the array is physically shifted 1/2 pixel biaxially to achieve up to 50% higher horizontal and vertical resolution. This would make the theoretical maximum resolution of the image, 1440x810 pixels, even though each CCD has only 960x540 photosites. Internally the camera uses 1920x1080.
The HVX200's resolution is recorded at 960x720 for 720p mode, and 1280x1080 for 1080i mode in 60 Hz territories; in 50 Hz (PAL) regions it is recorded at 1440x1080. The sensors employ variable scanning rates from 2 Hz to 60 Hz (NTSC version) or 50 Hz (PAL version) and are always capturing progressive images. The images are always scanned from the chips at a resolution of 1920 x 1080. Those images are then downsampled to a size appropriate for the recording format (for DVCPRO that means 720x480 NTSC or 720x576 PAL; for DVCPRO HD it means 960x720 for 720p or 1280x1080 for US/NTSC 1080i/p, or 1440x1080 for EU/PAL 1080i/p).

Features
The HVX200, successor to the Panasonic DVX100, supports:- Variable frame rates and resolutions, including (in the NTSC version):
- 1080: 60i, 30p, 24p
- 720: 60p, 48p, 36p, 32p, 30p, 26p, 24p, 22p, 20p, 18p, 12p
- 480: 60i, 30p, 24p
- The camera also contains the following unsupported frame rates that can be reached with a hack ([2] [3]):
- 720: 2,3,4,6,8,10,14,16,23,24.9,27,28,34,38,40,42,44,46,50,52,54,56,58 fps.
- Professional/Robust format (DVCPRO-HD)
- Tapeless recording using the P2 storage media (Available in 8 GB and 16 GB sizes currently, with the 4 GB option dropping off the market after the introduction of the 16 GB cards in June 2007.) A hard disk recording device has also been announced by various 3rd-party vendors (FS-100 Firestore, Shining Corp's Citidisk HD and Cineporter from Spec-Comm, but due to lack of market interest, the CinePorter™ will NOT be going into production.)
- Audio: 48 kHz 16-bit 4-channel PCM audio, 2xXLR
Digital Cinema and Videography
The AG-HVX200 is popular with users because the DVCPro HD recording format helps minimize compression issues and maintain color fidelity compared to similarly priced HDV and DV cameras. The variable frame rate options of the AG-HVX200 are also more extensive than in competing cameras. HDV serves a different market by recording high-definition video on inexpensive miniDV and DV tapes, with some potential quality compromises from using inter-frame compression and reduced color sampling.Competitors
The main competitors of the HVX200 as as of August, 2007 are as follows (all of which use HDV recorded on miniDV tape):- Sony HVR-Z1U
- Sony HVR-V1U
- Canon XH-A1
- Canon XH-G1
- Canon XL-H1
- JVC HD100U and HD-110U
