The GY-HM100 samples the image at 4:2:2 and can provide a live uncompressed 4:2:2 output via the HDMI port on the back of the camera. It is possible to store and edit 4:2:2 data if you have an input device on your computer, such as the Blackmagic Intensity Pro card. In live broadcast environments, the HDMI signal can be cross converted to HD-SDI with an outboard adapter.

Recording to SDHC memory cards provides a significant reduction in bandwidth. In this case, the signal is subsampled to 4:2:0 and compressed using the MPEG2 codec. This system provides outstanding picture quality and perfectly matches the ATSC digital broadcasting system used in the United States.
