WAYNE, N.J.—JVC Professional Video has announced that the Version 2.0 firmware upgrade for its 4KCAM camera line is now available. With the new upgrade, GY-LS300 adds a log gamma setting and a Prime Zoom feature, while a histogram and new 70Mbps 4K recording mode is added to all three camcorders.
The ‘JVC Log’ gamma expands dynamic range on the GY-LS300 by 800 percent, 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 and Cinema 2K, which offer 17:9 aspect ratio for digital cinema presentations. Additional settings include a spot meter, black paint setting, and color matrix adjustment.
The Prime Zoom feature allows zoom in/out with fixed-focal lenses using the GY-LS300’s zoom rocker. It uses JVC’s Variable Scan Mapping technology to electronically adjust the active area of the Super 35 CMOS sensor. The Prime Zoom can also be used as a lens extender.
With the new 70Mbps mode, all of JVC’s 4KCAM camcorders can record 4K footage on Class 10 SDHC/SDXC memory cards. The new histogram is added to help check exposure; histogram is accessible through a user button.
Owners of the GY-LS300, GY-HM200 and GY-HM170 can receive their free upgrades at pro.jvc.com/firmware.
