Improving Your Lecture Capture Recordings

  • The College of Engineering Lecture Capture System is an automated option for recording most classroom courses and events.
  • Video and audio of the instructor is recorded, along with any slides or other content being projected.
  • The system will automatically create a nice web-based viewer with thumbnail navigation and separate views for video and slide content.



A typical classroom is a challenging space for recording. Most were not designed with video in mind, so lighting and layout are not ideal. The following tips may help you increase the production value of the recordings you make using the lecture capture system:

  • Set the camera's preset - When an automated recording starts, the recorder positions the camera to cover a wide area around the lectern. You can adjust this preset to better match where you stand while lecturing. The preset that is recalled at the start of a recording is the "wide" preset, which you can set using the manual recording controls.  More information is available on using the manual controls, or contact CAEN for assistance.
  • Use the wireless microphone - Every classroom with lecture recording capability includes a clip-on wireless microphone. Using this microphone will give the best audio on the recording. Clip it to your clothing about 6 inches below your chin, and place the transmitter in a pocket or clip it to your clothing. Remember to turn it on by sliding the Off-Standby-On switch all the way to On. Note that most classrooms also have a backup mic that will pick up audio if the wireless microphone is not used, but the wireless microphone gives the best results.
  • Turn off your mobile phone - Radio transmissions from mobile phones can cause a chirping/clicking sound on your recording and/or from the speakers in the room. If you must leave the phone on, keep it as far as possible from any microphones and A/V equipment.
  • Avoid using the chalkboard/whiteboard - The camera generally does not pick up writing on the board well enough to be visible on the recording. A good alternative is to use the document camera, which can display on the projector anything you write on paper. Another option is to use a pen-enabled device such as a Tablet PC to electronically draw to the projector. These methods have other advantages, such as being able to start with a partially filled out page, and being able to save and post the writing to C-Tools after class.
  • Avoid using a laser pointer - The laser dot is not picked up well by the recorder, and can even be difficult to see in the room. A simple alternative is to display the computer's mouse cursor.
  • Match your laptop's resolution to the projector - The native resolution of all our classroom projectors is 1024 x 768 (60 Hz preferred). Set your laptop to this resolution to eliminate black bars, stretched images, or even the possibility of no slides showing up at all. Other resolutions may work, but if you experience problems try changing to the projector's native resolution.

When recording video:

  • Adjust the room lights to provide as much light at the front of the room as is possible, while still ensuring good visibility of the projection screen (if being used).
  • Wear camera-friendly clothing. Generally choose solid pastel colors, and avoid fine patterns, white, or dark colors. Avoid jewelry which could add audible noise or bright flashes for the camera.
