Video recording technology

MediaRecorder enables synchronous video recordings from up to eight different video and audio sources at a time. Compatible with both The Observer® XT and FaceReader , and a broad range of cameras, it is the ideal recording tool.

  • Easy to use.
  • Flexible software that fits your needs.
  • Versatile, extra equipment for mixing (PiP) or combining videos is not necessary.
  • High quality recordings at HD in MP4 format.
  • Record videos with or without sound. 
  • Capture the full computer screen on which MediaRecorder is installed.
  • Easily copy external displays.
  • Accurate synchronization.
  • Robust software tool for precise and flexible recording.
  • Playback of videos available via Windows Media Player.
  • Compatible with Windows 7 and Windows 10 (64 bit computers).


MediaRecorder can be used with the newest state of the art video recording technology. It is compatible with a broad range of high-quality digital cameras based on today’s technologies, as well as analog systems. Using MediaRecorder, you can easily record the same scene from different angles or record in up to eight rooms. This makes recordings fast and accurate! 


MediaRecorder is easy to operate which for example means that you can switch between different cameras and control them with your mouse or joystick. With IP cameras, Pan-Tilt-Zoom is now possible: position the cameras precisely with a joystick or mouse (no additional hardware needed). For example, you can record classroom interaction and use MediaRecorder to combine the videos. The first camera is following the teacher and the other three cameras are following three children. The video cameras can be controlled with a joystick and recording can be started manually or another software package can be used to command the MediaRecorder.

Fully integrated 

The key to synchronization is integration. Files recorded with the MediaRecorder can be used in The Observer XT making it a fully integrated package. Once you have set up a project in The Observer XT, all data and video material are stored in one database and shown in one software application. It gives you complete control over video, and guarantees a frame accurate link with your data. By controlling the MediaRecorder from The Observer XT, you can manage all your data with one application and ensure that all your videos and audio is recorded in perfect sync. You can also start other tasks from The Observer XT, such as facial expression analysis with FaceReader. By using The Observer XT as the main project manager, you stay in control of your collected data.

Picture in Picture

When studying interactions from several different angles, it’s helpful to see what your participants are looking at. Videos from four cameras can be combined into one file, so you can inspect your entire setup in one view. It is also possible to display up to three small video images in one main video image (Picture in Picture). You can choose the position and size of the embedded video images within the primary video display.  

Record rapidly occurring behaviors 

When you are studying rapidly occurring behaviors, it is ideal to record videos and code them afterwards with The Observer XT; the playback functionality of The Observer XT allows you to play back the videos at a low speed, and code behaviors in greater detail. With special cameras, you can even record up to 100 video frames per second. So you can record fast movements accurately; for example, for sports research.

Stand-alone option 

You can use the MediaRecorder as a stand-alone tool, or can run it on your computer in the lab, at home, or in a classroom to record, combine, and file your video recordings. Then use the video files later on your office computer running The Observer XT. This is an easy and efficient way to increase productivity (MediaRecorder is compatible with Windows 7 and Windows 10, 64 bit computers). 

Complete solution 

It is also possible to create your own solution or ask Noldus to assist you with designing the entire lab set-up as there are so many possibilities to consider. MediaRecorder is available as 4, 6, or 8 recording solution. Record up to four high quality videos simultaneously or, for larger observation labs, extend this number to eight. The choice is yours!
