An interview from the 2015 NAB New York Show with Craig Yanagi of JVC Professional. JVC is a leading developer and manufacturer of sophisticated audio and video products that use superior technologies to deliver high quality sound and images. JVC offers a complete line of professional equipment for the broadcast and professional video marketplace including studio cameras, professional camcorders, 3D and 4K camcorders, Blu-ray recorders and precision HD studio monitors. In this interview Craig talks with us about a new firmware update to their JVC GY-LS300 4K Super 35 Camera.
The newly announced Version 2.0 firmware upgrade for the GY-LS300 4KCAM handheld Super 35 camcorder adds a “JVC Log” mode that practically duplicates the look of film, plus new Cinema 4K and Cinema 2K recording modes, a unique Prime Zoom feature that uses the camera’s innovative technology to allow zoom capabilities when using prime lenses, and a histogram.
With the new JVC Log mode, the GY-LS300 delivers wide latitude and high dynamic range – up to 800 percent – to rival the look of film. The camera’s Super 35 CMOS sensor delivers a higher contrast ratio between dark and bright areas within the frame without saturation while providing details within highlights and shadows. V2.0 also adds 4096 x 2160 Cinema 4K and 2048 x 1080 Cinema 2K recording modes at various frame rates, each with a 17:9 aspect ratio for digital cinema presentations.
Prime lenses have a fixed focal length, but the GY-LS300’s new Prime Zoom feature takes advantage of JVC’s unique Variable Scan Mapping technology, which was created to electronically adapt the active area of the camera’s image sensor to provide native support of various lenses when paired with third-party lens adapters. When used with a Micro Four Thirds (MFT) prime lens, the image can be adjusted between the maximum scan area and minimum scan area using the camera’s zoom rocker. As a result, the camera can deliver 2.3x maximum zoom for HD or 1.25x maximum zoom for 4K. The new Prime Zoom feature can also be used as a lens extender for zoom lenses.
Version 2.0 adds a histogram display, which is useful for checking the exposure by showing the brightness distribution of the image. The function is accessed through a convenient user button, and the range can be set to provide top and bottom limits. Beyond a histogram, V2.0 adds a color matrix adjustment, spot meter for setting exposure values, and black paint setting to precisely adjust color temperature of master black. Additional performance and streaming enhancements include a new 70Mbps recording mode, which makes it possible to record 4K on economical Class 10 SDHC/SDXC memory cards.
Designed for cinematographers, educators, documentarians, and broadcast production departments, the GY-LS300 is the flagship camera for JVC’s new 4KCAM product line. It accommodates a variety of workflows with the latest advancements in 4K imaging and efficient encoding for seamless workflow integration. It also includes a built-in HD streaming engine with Wi-Fi and 4G LTE connectivity for live HD transmission directly to hardware decoders, the Wowza Streaming Engine, and the ProHD Broadcaster server powered by Zixi. With support for various streaming protocols including RTMP, the cameras can stream directly to content delivery networks (CDNs) like Ustream and popular Web sites like YouTube.
Free for all current owners, the firmware upgrade is now available.
