FAQ
-
Q: How does SE 4K differ from the original CineView SE?
A: SE 4K transmits up to 4K30 (the original is limited to 1080p), extends range to 400 m, uses H.265 encoding, can control Sony / Canon cameras, and has USB-C ports for wired phone connection on both the transmitter and receiver.
-
Q: Can it transmit 4K over SDI?
A: No. The SDI ports are 3G-SDI, supporting up to 1080p60, and when the transmitter receives 4K HDMI, the receiver's SDI port has no output. For 4K30, input to the transmitter and output from the receiver via HDMI.
