The CineTreak Stream Master SDI Video Switcher can accept 4K signals when using HDMI inputs 1 and 2. But the internal processing is still 1080p HD. And the program is output at up to 1080 60p. Also the SDI ports are all 3G-SDI for up to 1080 60p signals.

does this take SDI input 4k UHD signal out from SONY PXW-x70 video cameras?
Asked by: ramesh
The CineTreak Stream Master SDI Video Switcher has 3G-SDI which cannot receive 4K whatsoever. Also to be noted, the Sony PXW-X70 Professional XDCAM Compact Camcorder also only has 3G-SDI and this does not output 4k.
