Lecture Capture Services

Ensemble Logo

The University has been using lecture capture system (LCS) for years. This year, we replace the old LCS with the “Ensemble Video” platform which improves the accessibility of the video on mobile devices with better video quality. The lecture capture services enable lecture’s screen along with the speakers’ video and sound captured to digital form. The dual-video could then be viewed in picture-in-picture mode at the discretion of the viewers. With the growing use of video in teaching and learning, we will continue to enhance the services to support the needs.


About "Ensemble Video"

  • It captures lectures and speeches in our large lecture rooms to digital form for later web access or on mobile devices.
  • It captures the projected slides/computer screen of the presentation, the voice of the speakers through the microphone and the image of the speakers to form a dual-video.
  • Once captured and processed, students or end users could re-visit the lectures and presentation through a web browser or mobile devices. Normally it takes one day to process or encode the video.
  • While playing the dual-video, viewers can select the viewing options by clicking on the icon in the bottom right corner of the video player. The viewing options include layouts such as picture-in-picture, side-by-side and individual video.

Tips and Limitations

  • For good sound capture or if speakers need to move around during the lecture, speakers might need to use wireless microphone.
  • Viewers of the video recorded by Ensemble Video should use broadband or faster network to view the video smoothly. For best viewing experience, it is recommended to use modern browser such as Chrome, Edge, Firefox and Safari.
  • Setup of Ensemble Video requires many cabling and integration with the Public Address system and camera. Only large lecture rooms have the camera and PA system in place.
