Le GZ-MG505 rassemble un disque dur de forte capacité 30Go avec un capteur 3-CCD 5 Mégapixels, Cet appareil (au prix non encore déterminé) souligne les efforts de JVC sur le marché du caméscope à disque dur et propose avec ce GZ-MG505 son nouveau fer de lance. Nous avons reçu un long communiqué de presse très intéressant car détaillant les technologies mises en œuvre (en anglais malheureusement). Nous aurons certainement l’occasion par la suite de vous proposer un test complet.
Aujourd'hui, JVC (Victor Company of Japan) annonce le lancement de son caméscope à disque dur qui combine un capteur d'image 3-CCD pour une image vidéo de grande qualité, avec la possibilité d'enregistrements de très longue durée grâce à l'utilisation d'un disque dur interne de 30Go. Ce modèle a déjà reçu le Prix TIPA (Technical Image Press Association) du meilleur caméscope 2006.
Le nouveau JVC EVERIO G – GZ-MG505 – comme les autres modèles de la gamme EVERIO G, permet d'éviter d'avoir à emporter des cassettes, disques ou autres médias avec vous, tout en vous laissant la possibilité d'enregistrer sept heures en qualité DVD cinéma, ou dix heures en qualité DVD-Cam. Pour remettre cette capacité dans le contexte, il faudrait 22 DVD 8cm simple face (8cm / 20minutes) pour stocker 7 heures de vidéo en qualité DVD-Cam. En mode "ECO", plus de 37 heures de vidéo peuvent être prises sans avoir à changer de média.
Le GZ-MG505 se situe au sommet de la gamme EVERIO-G grâce à sa haute qualité d'image, rendue possible avec l'emploi d'un capteur 3 CCD qui utilise la technologie de décalage des pixels pour obtenir une image de 5 Mégapixels en mode photo. En plus de la résolution native 16:9 (1173 x 660 x3 pixels effectifs) et 4:3 pour les films DVD de qualité supérieure, ce capteur d'image haute performance permet d'obtenir des photos JPEG de haute résolution de 2560 x 1920 pixels. Pour couronner le tout, le disque dur peut stocker près de 10.000 photos sans arrière-pensée, tout en laissant suffisamment de place sur le disque pour enregistrer des heures de vidéo même dans la meilleure qualité. Pour information, un tel nombre de photos nécessiterait 416 pellicules 24 poses sur un appareil photo conventionnel, rendant le GZ-MG505 le compagnon idéal de vos vacances pour voyager léger.
En dépit de son important capacité de stockage, le poids du GZ-MG505 n'est que de 450g, ou 510g avec la batterie et le cache objectif. Il est si petit que l'on peut l'emmener partout. Son design classique incorpore un écran LCD 16:9 de 2,7" (6.9cm) de diagonale permettant d'afficher correctement les images tournées en 16:9 natif, aussi bien en lecture que pendant le tournage. L'entrée micro et la griffe porte accessoires offrent une grande flexibilité pour la prise de son, et l'éclairage. De plus, grâce aux interfaces multiples, transfert USB 2.0 (12x), logiciels de montage et d'édition (Mac et Windows ®), il devient facile de partager tous ses souvenirs merveilleux.
Performance 3-CCD/5-Mega
L' Everio GZ-MG505 crée des images très fines et très réalistes grâce à l'utilisation d'un capteur CCD 1.33 megapixels (1.23 effectif) dédié à chaque couleur primaire – Rouge, Vert & Bleu). Le prisme optique JVC, et les 3 CCD sans filtre utilisant la technologie "Décalage de pixels" (Pixel shift) permet d'obtenir des photos de 5 mégapixels. En utilisant simplement le décalage de pixels, comme sur les caméras professionnelles, la capture des 1.228.000 pixels est doublée dans le sens horizontal, comme vertical, créant ainsi une image réellement colorée dont le nombre de pixels est multiplié par 4 en photo (En mode photo le GZ-MG505 utilise 1280 x 960 pixels effectifs pour chaque couleur primaire – RVB). Grâce à leur excellente dynamique, les images vidéo sont très claires et réalistes, et les photos numériques atteignent 2590 x 1920 pixels, permettant de superbes impressions 20x30cm ;
Other Image-Enhancing Features
To fully capitalize on the camera’s inherent picture performance, JVC’s Megabrid Imaging Engine separately processes video and still signals, providing optimal processing for each. Megabrid technology assures high sensitivity and a high signal-to-noise ratio for moving pictures, and clear, high resolution progressive still images. The GZ-MG505 is also the first model to feature new processing that increases chroma saturation and luminosity, which together provide an exceptional picture with brilliant colours, especially noticeable in more natural-looking flesh tones and greens.
Also present is JVC’s 3D NR (3-Dimension Noise Reduction). Conventional 3D noise reduction offers limited accuracy since it compares field A and field B that make up a frame with different sets of odd and even scanning lines to compensate for noise. JVC’s 3D NR technology compares field A to field A, and field B to field B across two frames so that the scanning lines are identical and noise can be reduced more accurately. As a result, the signal-to-noise ratio is improved by 2 dB and noise reduced by about 30 percent. Flicker is eliminated and colour reproduction is improved, enhancing overall picture quality.
The Everio GZ-MG505 also features a high resolution 10x optical zoom (8x for stills) JVC lens, with one of the widest 16:9 angles available for video – 35mm equivalent to 41.2mm (43mm for 4:3 stills). To achieve 3CCD high-resolution images, the zoom lens is a seven group ten element system developed originally by JVC. Chromatic aberration is decreased by using low dispersion glass lens materials. A combination of ultra-high-density and miniaturization was achieved with three aspheric elements. In addition, highly accurate 3 CCD registration and multi-angle glass fixation technology developed by Fujinon for broadcast cameras are also used.
MPEG-2 Video Recording for DVD-Movie Quality Footage
JVC is a leader in MPEG-2 encoding technology for both professional and consumer camcorder applications. The Everio G Series GZ-MG505 offers seven hours storage at 9 Mbps, which is close to the maximum bit rate for DVD movie quality recording, or 10.5 hours at 6 Mbps, comparable to DVD Cam recordings. Either way, the high quality MPEG-2 recordings are in the same format used in DVD so there will be no quality loss when burning them to DVD, and no time and quality wasting conversion. Two more modes are available for even more recording time, offering sufficient quality for normal TV-connected viewing or for uploading to the Internet.
Recording mode Shooting time Bit rate

Ultra (DVD Movie) 7 hours 9
Fine (DVD) 10.5 hours 6
Norm (TV) 14 hours 4.5
Eco (Internet) 37 hours 1.7
*Combined A/V rates.
Easy Access to Recordings
The benefits of recording video to a hard disk are the same benefits that have made hard disk-based audio players so popular — random access to quickly locate desired material, the ability to effortlessly delete unwanted material, and easily rearrange the playback sequence. What’s more, there’s no danger of mistakenly recording over something you want to keep.
A new feature for this year’s Everio G Series is Event Selection. In addition to accessing video clips by Thumbnail image or Date, with Event Selection the user can pre-assign while shooting or later assign a convenient topical category with Icon. Simply calling up the event type, like “Birthday”, brings up all events associated with it. Event categories can also help make playlists for “in camera” video programmes or for burning to DVD. And with remote control operation, it is possible to connect the Everio G camcorder to a TV and operate it from a distance, just like a DVD deck.
Hard Disk Protection and Stability
A challenge in designing and building a hard disk camcorder is protecting the disk from shocks and vibrations. One way this is done in the Everio G camcorders is through a unique floating suspension system that effectively dampens vibrations through advanced polymer shock absorbers. Another security measure familiar to notebook PC users is its gravity (G) force sensor system that automatically senses sudden acceleration such as in a free fall situation, and turns off the power to defend the hard disk so that a head crash can be avoided even when the unit is dropped.
Make Full-length DVDs Easily, With or Without a computer
Everio GZ-MG505 offers built-in DVD burner control allowing it to be directly connected to the optional JVC DVD burner, the CU-VD10 SHARE STATION. The camcorder connects to the burner via a USB cable and the burner is easily controlled by the camcorder. The Everio converts its .mod video files to DVD Video format so the SHARE STATION can create long playing full size 12cm DVD-R discs that play on most DVD players.
Advanced Interfaces for PCs and Printing
For use with Windows®, the GZ-MG505 comes with CyberLink’s PowerProducer™ 3 NE for authoring DVDs, PowerDirector™ Express NE for editing, and PowerDVD 5 NE for playback. For Macintosh users, JVC provides PIXELA’s Capty MPEG Edit EX for simple editing and file conversion to popular editing formats, and “mono DVD” for easy DVD authoring. An available option is Capty DVD/VCD 2 for enhanced function DVD authoring.
For quick downloading to a PC, simply connect the camera via its USB 2.0 interface. All transfer is digital-to-digital so there is no quality lost in the process. The accelerated transfer speed for this year’s Everio G Series including the GZ-MG505 is 12-times real-time speed, so a top-quality Ultra mode 60-minute (4GB) video clip can be transferred in about 5 minutes. And since the camera supports PictBridge, it can be connected by its USB terminal to a compatible printer for easily printing of stills directly from the camera.
This model also has an SD Memory Card slot for direct transfer of digital still image data. DPOF (Digital Print Order Format) support allows the menus on the camera screen to be used to conveniently select images and quantity before giving removable media to a printing service. The JPEG images themselves conform to DCF, PIM 3 and Exif 2.2 for optimised print quality.
