Chapter 1 Overview
The AG-HPX370P/AG-HPX371E P2 memory card camera-recorder features a camera unit equipped with a newly developed 1/3-inch 2.2-megapixel 3MOS sensor and a recording and playback unit that provides AVC-Intra 100 compression recording as standard to offer HD full pixel and full sampling for high sensitivity, superb image quality, and high-quality video.
It handles multiple HD and SD formats: AVC-Intra, DVCPRO HD, DVCPRO50, DVCPRO and DV compression recording. The P2 card provides a reliability, speed and IT functionality that no other media can match and is destined to revolutionize recording and editing paradigms.
Multiple HD/SD formats
The camera supports both the HD and SD video formats making it ready for news gathering, program production and film making in a wide range of professional applications and content production. In 1080i/720P HD recording for broadcasting, the camera uses the highly reliable AVC-Intra or DVCPRO HD codec while also supporting SD multi- codec (DVCPRO50, DVCPRO or DV) recording capability.
The AG-HPX370P/AG-HPX371E provides high quality and uncompressed, 16-bit, 48 kHz, 4-channel recording of audio in all formats.
Variable frame rate makes speed effects possible (in the 720P format)
The AG-HPX370P/AG-HPX371E comes with the variable frame rate feature developed for the VariCam HD Cinema camera. In 720P mode *1, the frame rate can be set to any of 20 steps between 12P and 60P (50P). This puts features such as undercranking (dropping frames) and overcranking (high frame rate) for quick motion and slow motion cine-like effects at the disposal of the camera crew.
Native mode/over 60P (50P) mode selectable
Native mode:
Playing back a recording made at a frame rate set in the camera at the normal rate provides speed effects without using a frame rate converter. Native mode also extends the recording time of a P2 card.
720P over 60P (50P) mode:
Use of a DVCPRO HD recorder such as the AJ-HD1400 or the AG-HPG20 P2 portable recorder allows you to make backup recordings of DVCPRO HD streams output from the DVCPRO/DV connector. *2
1080/480 24P advanced mode
Recording 1080/24P or 480/24P makes it possible to select 24PA (advanced) mode *3. Using 2:3:3:2 pulldown, the 24PA mode performs 60i conversion to enable nonlinear editing *4 maintaining an image quality that is better than normal 24P (2:3 pulldown). Recording at 30P applies a 2:2 pulldown.
Camera Unit Features
Progressive 3MOS sensor
The AG-HPX370P/AG-HPX371E is equipped with a newly developed 1/3-inch 2.2-megapixel 3MOS sensor that enables high-sensitivity HD full pixel recording for high-resolution video.
14-bit digital circuit
The high-performance DSP (Digital Signal Processor) in the camera offers 14-bit signal input and 20-bit internal processing. It handles gamma settings and other adjustments for each R/G/B color in 1080/60i (50i) video as well as conversion to all HD/SD formats (P/I conversion, line conversion and down conversion). Because of this high-quality images can be produced in all video formats.
Seven gamma curves including cine-like gamma
To expand camera capabilities, the AG-HPX370P/AG-HPX371E offers seven gamma curves including cine-like gamma to easily produce recordings with the characteristic warm tone of film.
*1 1080 and 480 (576) recording is performed at a fixed frame rate of 24P/30P (25P).
*2 The AVC-Intra mode does not allow the output of a DVCPRO HD stream from the DVCPRO/DV connector. *3 Not available with the AVC-Intra codec.
*4 For details on compatible systems, visit the support desk at the following website. http://pro-av.panasonic.net/
24P and 30P indicate recording at 23.98P and 29.97P, respectively, while 60P and 60i indicate recording at 59.94P and 59.94i, respectively.
