The GY-HM150U Compact Handheld 3-CCD Camcorder from JVC is an ultra-compact professional HD camcorder that records 35 Mb/s Long-GOP MPEG-2 to SDHC/SDXC cards. Offering an integrated 10x Fujinon zoom lens and three progressive CCD imagers, the camcorder debuts a Dynamic Digital Signal Processor from JVC that processes the full 1920 x 1080 signal, regardless of recording mode. Despite its tiny size, the HM150U slides right into most professional workflows in ways that far surpass the flexibility of AVCHD-recording models.
The camera records 35 Mb/s 1080i video natively as QuickTime files for effortless integration with Final Cut Pro, or it can be saved in MP4 format for compatibility with XDCAM EX workflows. And building on the success of its predecessor, the HM100U, the HM150U adds a proprietary Rotary Optical Image Stabilizer (ROIS), pre-rec & time-lapse recording, and standard-definition recording, for compatibility with SD workflows that require fast turnaround times.
The HM150U also features wider options for recording to its two SDHC/SDXC card slots: You can set it record either sequentially or simultaneously to both cards, for instant backups. With dual 64 GB SDXC cards installed, you can record full HD video for hours without changing out media. This endurance, coupled with its small size and removable handle, make the HM150U a strong choice for capturing fully professional video under adverse conditions that might require surreptitious operation.
The focal length of the lens ranges from 3.7-37 mm (39-390 mm at 35 mm film equivalents), offering a good balance of wide angle and zoom. For wider angle shooting, the built-in lens hood can be removed and an optional wide-angle converter fitted.
Focus is controlled manually or automatically. A smooth servo zoom is controlled with a conventional rocker on the handgrip, or manually on the lens. For close-up shooting, a macro mode allows for shooting subjects as little as 2-inches away from the lens. Exposure (iris) is automatically or manually controlled, letting the shooter adjust the depth of focus by selecting the appropriate F stop. The current F stop is displayed in the viewfinder in the manual mode
The GY-HM150 supports all major HD signal formats, including 1920 x 1080, 1440 x 1080, and 1280 x 720
For users of all major NLE systems, including solutions from Adobe, Avid, Grass Valley, Sony, and Apple, the GY-HM150U supports the MP4 file format, which can be brought into your editing system without re-encoding. HDV-compatible M2T files can also be created from these MP4 files using the ProHD Clip Manager (Version 1.1).
Finally, the popular type-2 AVI file format can be recorded in SD for easy import into almost all current and legacy NLE systems
Dual SDHC/SDXC card slots make the GY-HM150U a truly versatile camcorder. Footage is recorded either to both cards simultaneously, or from one card to the other in relay. Simultaneous recording means that it easily creates backup or duplicate files while shooting without the need for any external equipment – either for a client copy or simply for peace of mind. In relay recording mode, shooting is continuous and seamless over multiple cards. When one card is full, the camcorder switches seamlessly and automatically to the other card. And because cards are hot-swappable, there is in effect no limit to the continuous shooting time in any mode, even with lower capacity cards. Hot-swappable media also means it is possible to start editing footage from one card while still shooting to the other. The dual card slots also offer the flexibility of scene-by-scene card selection. Additionally, while the Rec trigger is used to pause and unpause recording on one card, the other card can act as a continuous backup that overrides the pause function. Also, when recording, clips separated with the Rec trigger can be saved as a conjoined clip using Clip Continuous mode, and the Clip Cutter mode allows you to separate clips by using the User button as a trigger.
SD media offers the best combination of price, availability, capacity, reliability, and transfer speed. With no moving parts and no pins or other extrusions, SDHC/SDXC cards are both durable and reliable, and compare favorably with all other media types on a cost-per-minute basis
