Environment needed
- If a full body shot is needed, the minimum distance for shooting must be considered for the camera to capture the complete image. We suggest that space is as following sizes: 5x5x3.5m
- Chroma key wall: The primary colors for the virtual set background are blue and green. The clothes color of the presenter can determine the background color.
- Ambient Lighting: Lighting determines the aesthetic feeling for the final chromakeyed virtual set. Ambient lighting ensures you of isolating the talent from the background the best. Recommended is to use three fill lights and six ceiling lights.
Chromakeying
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!
Interactive touch screen
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.
Video recording and recalling
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.
