Simple Production by a Single Operator

Live Stream and Record Simultaneously
The VGB-4000 system with the H.264 video streaming service 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. There is no need for post-production, which improves the efficiency of production to produce teaching videos.
4:4:4 Broadcast-Level Chromakeying
The VGB-4000 system applies the broadcast-level DVK-400 for chromakeying. The DVK-400 supports resolutions up to 2160p60 with a 4:4:4 10-bit image processor, providing a professional real-time chromakey effect. The chromakey parameters such as brightness, contrasts, color, and saturation are available to adjust by the user. With the careful adjustment, the lecturer's image can perfectly combine with the background, just like in the actual scene.
The system adopts HDR-90 ProRes 4K Video Recorder to record course videos. The recorder supports UHD 4K recording and is compressed in 10-Bit 4:2:2 ProRes. The built-in 5-inch touch screen allows user to easily configure parameters and view the live video. The HDR-90 is not just for a single-camera setup, and the recorder can record up to four 1080p60 streams simultaneously to separate ProRes files. All files are synced with the same time code, making it easy for tracking during post-production.
Virtual Sets and AR Objects
The system includes multiple sets of free virtual backgrounds. The lecturer can choose their favorable virtual sets for the backgrounds. They can also apply the images and animations from the laptop as backgrounds to create different teaching situations.

Look Back Kit Makes Presentation Much Easier
