The Canon XF705 UHD HDR camcorder with HEVC recording records 4K to SD cards.
Canon's newest camcorder for professional videographers in the XF705. With styling reminiscent of the mini DV ZL series, the camcorder meets the needs of broadcast and video production applications where videographer want to capture UHD HDR video live, or recording to memory cards. For live capture the camera has genlock and 12G-SDI out.
The camera has a 1in UHD sensor (3840 x 2160 pxls) at its core and an integral L-series 15x Zoom, 8.3-124.5mm (35mm equivalent 25.5-382.5mm), f/2.8-4.5. The larger sensor promises better low-light performance than earlier XF cameras with a minimum subject illumination of 1.5lux.
With 4K capture calling for accurate focusing, the camcorder has Canon's dual-pixel AF, which can also be used as a focus assist for manual focus. 5-axis optical image stabilisation provides for steady shots.
The three lens control rings have wide spacing for easy operation and end stops, and the camera has an ND filter turret with three densities (ND 1/4, 1/16 and 1/64).
The camera offers a choice of compression codes: H.265/HEVC or MPEG-4 AVC/H.264, in an MXF wrapper. HDR recording can use PQ, HLG or Canon Log 3. With the XF-HEVC codec at 2160P60, maximum data rate is 160Mbps, well within the limits of the current round of SD cards.
The XF705 Professional Camcorder offers the ability to stream video live online using IP transmission in either the H.265/HEVC or H.264/AVC encoding format. Live H.265 streams (16Mbps at 59.94p) can be used to reliably distribute either 4K UHD or Full HD data efficiently to a variety of TV and social media platforms.
The livestream can be viewed directly from the camcorder using the on-board LCD monitor, sent to a standalone HEVC IP encoder or redirected to a 4K UHD monitor for a confidence check and public viewing. In addition, Live HDR data (Message/Mastering Display Color Volume) can be added in the H.265 stream if required to help improve picture quality.
