JVC GY-HMQ10

Last updated by Yermy Weiss on May 28

The JVC GY-HMQ10 is a small, relatively affordable, ENG style camera built around a single 1/2.3” (6.2mm x 3.5mm) 4K CMOS sensor. The despite its compactness the HMQ10 still manages to offer a 10X optical zoom with OIS, two XLR audio inputs, as well as a flip out LCD and viewfinder. The JVC HMQ10 is well suited for run and gun type work and can easily be operated handheld. The relatively small image sensor gives the HMQ10 a deep depth of field making focusing much easier, it even has autofocus.  However, the small sensor does mean the HMQ10 will struggle in low light and have a lower dynamic range then cameras with larger image sensors. The camera is also a fully functional HD camera and can record AVCHD into a single SDHC or SDXC memory card.

4K on the JVC GY-HMQ10

The JVC GY-HMQ10 has one of the most unique ways of recording 4K footage. Effectively the GY-HMQ10 records 3840 x 2160 QHD at 144 Mb/s in a heavily compressed H.264 based 4:2:0 codec. What it is actually doing is recording four separate 36 Mb/s 1920x1080 videos onto four SD cards simultaneously. Each 1920 x 1080 video is one quadrant of the full QHD image. The four quadrants can then be easily combined on a Mac OSX based computer into one 4K ProRes file with free downloadable software from JVC. If you are using a PC you will have to manually combine each of the four quadrants. This novel approach makes recording 4K very affordable since SD cards are very cheap, but it also makes 4K recording very labor intensive since all footage must be combined into a 4K file on a computer after shooting. 4K monitoring and playback is done via four separate HDMI out ports, each port representing one quadrant of the total QHD image. The HMQ10 can record QHD 4K in 24P, 30P, and 60P. A minute of recording will take up about 1.08 GB of space and an hour will set you back about 65 GB. Keep in mind that it’s spread out among four cards so four 64 GB SDXC cards would give you almost four hours of recording time.
