With DVK-400, you isolate the presenter from the green background and replace that background with something you choose yourself. We deliver a high quantity of backgrounds that will suit your lecture seamlessly.

Alternatively, you can upload your background and use that instead.
With keying occlusion, you can select a part of the screen that isn’t keyed. This way, you prevent the chromakeyer from keying out your presentation. Using green in your presentations is no problem this way!

Using a large touch screen is an easy way to lecture digitally. Showing your presentation and creating annotations on the screen is very easy to learn. The system can record the output of the digital touch screen as well to offer a full-screen rendition of your lecture.

Recording your video should be high quality, uninterrupted and safe from errors. The brand new HDR-90 ProRes 4K Video Recorder ensures all of that and more. By streaming the lecture through our NVS-33 h.264 streaming encoder and dvCloud, the file will be available on the VOD system as well, to be recalled at any desired moment.

One step Start/ Stop Recording
You don’t need to walk back and forth to the production station to start or stop recording during production. The FS-220 foot-switch allows you to start and stop recording with a tap of your foot.

The whole VGB-4000 system with the H.264 video streaming server allows you to live-stream the course scene to the web platform in RTMPS or RTSP mode or transfer it to a school or corporate training. Moreover, it provides the backup video recording function to record the video in MP4 format by inserting an SD card. Lectures can keep the recorded backup video by themselves.

The wireless microphones provide audio input. The audio gets embedded on the recorded video, so there’s no need to dub it later. The built-in audio delay ensures synchronized audio and video.

When producing video in a chromakey video, reference is always a thing to take in mind. You usually can’t see yourself with the background as this is just a green screen. The included LBK-1 look back kit ensures you are always in the proper position, while the teleprompter design helps you keep looking in the camera lens. An extra LED indicator shows you when you’re recording and when the recording is ended.

Different backgrounds will suit various lectures. Datavideo includes multiple backgrounds and easy importing tools to add your own.
