Datavideo SE-500HD

The SE-500HD is a four-channel 1080p HDMI switcher aimed at presentations and small live productions, letting you cut between consumer camcorders, action cameras, laptops, and tablets over plain HDMI. Two HDMI outputs carry a multiview on one and the clean program on the other, so the operator sees every source while the audience sees only the cut.

On-board effects include luma key for logo and lower-third overlays, split screen for two-shot interviews, and picture-in-picture for slides alongside a talking head. A built-in audio mixer takes stereo RCA and two microphone inputs and sends audio to RCA and a headphone jack, so sound and vision are handled from one box.
