4K is no longer reserved for theatrical cinema presentation; it is in demand at all levels of production. With Ultra HD recording, the GY-HM170UA 4KCAM Compact Professional Camcorder with Top Handle Audio Unit from JVC is designed to fulfill the requirement for professional functionality. It offers ND filters, custom-assign buttons, and professional audio inputs with manual gain control in a form-factor closer to a consumer camcorder. The camera records 3840 x 2180 UHD 4K in 24 or 30p, at a bit rate of 150 Mb/s, encoding the file in an .MOV-wrapped H.264 codec. With two SDHC/SDXC card slots, the camera supports dual, backup, and continuous recording. Besides 4K, it can also record 1080p at up to 60 fps in an 8-bit 4:2:2 50 Mb/s .MOV file, or in AVCHD for compatibility with consumer editing software.
For monitoring, there is a flip-out LCD screen with a 920,000-pixel panel, plus a 0.24" viewfinder with 1.56-megapixel resolution—the latter being especially helpful when working in bright daylight. For an external monitor, connecting to a live switcher, or recording video externally, there is an HDMI port with live 4K output. The included top handle audio unit features two XLR audio inputs for use with external microphones, offering switchable Mic/Line/Mic +48 inputs with independent gain control. It attaches to your camera's accessory shoe and secures with a slotted thumbscrew. It features electrical contacts on its foot that enable audio signal transmission to the camera without any cable required. An accessory shoe and shotgun mic clamp are available on top.

Ultra HD 4K Recording at 150 Mb/s
With dual card slots, the GY-HM170 is capable of recording UHD 4K (3840 x 2160) to either SDHC or SDXC cards that are at least UHS-I Class 3 or faster. It records at a bit rate of 150 Mb/s, encoding the footage in an .MOV-wrapped file suitable for editing in a number of applications.Live 4K Output through HDMI
You can output 4K live through the HDMI port for monitoring or connecting to a 4K switcher or external recording system. The HDMI port also allows you to preview previously-recorded content in its full Ultra HD glory.Also Records in HD
Since you may still need to deliver in HD, two HD codecs are offered as well. There is an .MOV-wrapped 50 Mb/s format that gives you 4:2:2 color space for compliance with many broadcast standards, as well as an AVCHD setting for shoots where file size takes precedence, or the footage needs to be edited using consumer editing software that only supports AVCHD.Dual Recording
Two SDHC/SDXC memory card slots support the following modes:- Dual recording: Recording a high resolution "master" to one card and a low resolution "proxy" to the other
- Backup: Recording the exact same format to both cards
- Continuous: Once the first card fills up, the camera rolls over to the second, allowing you to shoot indefinitely
