Datavideo SE-4000 12 input UHD videoswitcher (splitunit)

Datavideo SE-4000 — 12-input UHD videoswitcher with selectable 8 live channels and 5” touch control

The Datavideo SE-4000 is a UHD videoswitcher designed for live production. It provides twelve physical inputs and seven outputs, while letting you select eight live channels from the available inputs. You operate key functions using a built-in 5” touch panel for fast, on-board control.

Inputs and outputs

The SE-4000 accepts a mix of 12G-SDI and HDMI sources. You can choose which inputs run live, and you get multiple program outputs for simultaneous distribution.

• Inputs: 8 x 12G-SDI + 4 x HDMI (select any 8 live channels from the 12 physical inputs)
• Outputs: 4 x 12G-SDI + 3 x HDMI (seven outputs in total)

Control and scaling

The unit features a 5” touch panel that controls the switcher’s core functions. In addition, each input supports up/down scaling so you can match different source resolutions before mixing them live.

Compositing and effects

The SE-4000 includes multiple compositing and transition tools for live productions. These tools let you build layered scenes and switch between sources with various styles.

• 2 x Chromakey engines for live green/blue screen compositing
• 2 x DSK (Downstream Keyers) for graphics and lower-thirds
• 4 x PIP (Picture-in-Picture) windows for multi-source layouts
• XPT (Cross Point) routing capability
• Transition types: Wipe, Mix, DVE, Cut, and Stinger

Typical use cases

Use the SE-4000 for live event switching, multi-camera broadcasts, or corporate productions where you need flexible input selection and multiple outputs. The scaling per input and on-board chroma keying make it suitable for mixed-resolution sources and simple virtual sets.

FAQ

Question: Can I mix SDI and HDMI sources and use them as live channels?
Answer: Yes. The SE-4000 provides 8 x 12G-SDI and 4 x HDMI physical inputs and lets you select any eight live channels from the total of twelve inputs, so you can mix SDI and HDMI sources as needed.

Question: How many outputs can I send program video to at once?
Answer: The unit offers seven simultaneous outputs: 4 x 12G-SDI and 3 x HDMI, allowing you to feed multiple recorders, monitors, or downstream devices concurrently.

Question: Does the switcher handle different source resolutions?
Answer: Yes. The SE-4000 includes up/down scaling on each input, so you can match and integrate sources with differing resolutions before switching or compositing.

Question: What compositing tools are available for live graphics and keys?
Answer: The switcher includes two chromakey engines for green/blue screen work, two downstream keyers (DSK) for graphics and overlays, and four PIP windows for multi-source layouts.

Question: Which transition types can I use for switching between sources?
Answer: You can use Wipe, Mix, DVE, Cut and Stinger transitions to move between sources and create professional-looking live transitions.
