JVC Professional Video, a division of JVCKENWOOD USA Corporation, today announced the availability of its Version 2.0 firmware upgrade for its 4KCAM camera line. Upgrades are free for all current GY-LS300, GY-HM200, and GY-HM170 owners, and are available on the JVC Web site at pro.jvc.com/firmware. The upgrade adds log gamma setting and a unique Prime Zoom feature to the GY-LS300, as well as a histogram and new 70 Mbps 4K recording mode for all three camcorders.
For the GY-LS300, “JVC Log” gamma expands dynamic range by 800 percent with film-like latitude, preserving more information over the entire dynamic range of the Super 35 sensor for grading and manipulation in post production. New recording modes include Cinema 4K (4096x2180) and Cinema 2K (2048x1080), which offer a 17:9 aspect ratio for digital cinema presentations. V2.0 also adds a spot meter that allows the operator to monitor the dynamic range of select portions of the image and adjust the exposure accordingly, black paint setting to precisely adjust color temperature of master black, and color matrix adjustment.
Also new for the GY-LS300 is Prime Zoom, which allows zoom in/out with fixed-focal (prime) lenses using the camera’s zoom rocker. The system uses JVC’s unique Variable Scan Mapping technology, which electronically adjusts the active area of the camera’s Super 35 CMOS image sensor. The Prime Zoom feature can also be used as a lens extender for zoom lenses.
In addition to the 150 Mbps 4K recording mode, a new 70 Mbps mode allows all 4KCAM camcorders to record 4K footage on economical Class 10 SDHC/SDXC memory cards. The lower bit rate creates smaller, more manageable files. A histogram, useful for checking exposure by showing the brightness distribution of the image, has also been added. Shooters can access the histogram through a convenient user button and set the range to provide top and bottom limits.
The GY-LS300 is the flagship camera for JVC’s new 4KCAM product line, offering the latest advancements in 4K imaging and efficient encoding for seamless workflow integration. Its built-in HD streaming engine with Wi-Fi and 4G LTE connectivity offers live transmission to hardware decoders or content delivery networks (CDNs). JVC’s most affordable streaming camcorder, the GY-HM200 is ideal for corporate video and ENG with a 1/2.3-inch BSI CMOS imager, built-in 12x zoom lens (24x dynamic zoom in HD mode), and dual XLR audio inputs. The compact GY-HM170 features a heavy duty body with comprehensive video profile settings and controls for professional use.

As we enter the "Internet of Things" era, when all sorts of "things" are directly reachable over the internet, it should come as no surprise professional camcorders are coming along for the ride. They are actually somewhat late to the game, with smartphones already providing the ability to send a video out over the internet from the same device that captured it for quite some time. But connected professional camcorders have a lot to offer users looking for a streamlined professional streaming solution that video-capable smartphones can't deliver.
JVC is running ahead of the pack again with the GY-LS300, an affordable ($3,995), interchangeable-lens, Super35/variable-sensor area, 4K/HD camcorder that also features internal streaming capability, first model in a new product line.
