Supports 4K UHD Resolution Input
4K cameras are widely available and content online doesn’t require the full 4K resolution for streamed content. A single 4K camera can be utilized to obtain 4 cut outs or regions of interest. The KMU-300 is perfect for interview application with small panels or smaller houses of worship. With Social distancing becoming commonplace, the KMU-300 reduces the amount of cameras needed to get your production streamed live.
Make Your Streams More Reliable with SRT
Many broadcasters have experienced pixelated video during live streaming, often due to unstable network environments caused by bandwidth volatility and packet loss. Streaming RTMP over unreliable networks can cause issues. With dvCloud, you can now replace the RTMP protocol with SRT, which will fix most streaming issues you may have. SRT is better than RTMP because it handles problematic networks more efficiently. As a result, your viewers will experience a better stream, with less buffering and pixelization.

Create Your Professional Landscape Program
When using the landscape switching mode with the KMU-300, you can easily switch between the four selected frame pictures on the right side of the screen, full-screen mode, or computer output using the corresponding buttons.
The operation is simple and user-friendly. The frame selection area can also be adjusted as presets in advance, making on-site video production convenient.
You can also record your production on the dvCloud platform in h.264 format. After recording you can directly use this recording to upload it to your favourite content platform.
Direct SRT streaming to dvCloud prevents hickups and lag in your stream, especially when using slow or unreliable internet connections or when streaming large distances (for instance to the other side of the globe). Even if your destination does not support SRT you can still stream SRT to dvCloud and go to the destination in RTMP.
