In the webcast studios, you can simultaneously record yourself and the touch screen on which you can display PowerPoints or do formulas. While doing your presentation, a reference monitor shows what is being recorded.

At Media Lab, you can use our webcast studios to produce video-based educational materials.

The studios are designed to make it both easy and efficient for you to record videos of yourself to use in your teaching. You can run PowerPoint, screencasts, whiteboard-based teaching, and software demonstrations during your recordings.

Videos are produced with only a few clicks, and they are saved directly to the Science and Technology streaming server. This means that you do not have to wait to check your recordings, and you can immediately see if you need to make a new one. It is a simple and easy production solution.

Application

You can incorporate the videos in your Blackboard course to explain issues that students have trouble understanding, or even make recordings of entire lectures so that students can revise the curriculum whenever and wherever they need to.

You can also have students answer questions related to the videos so that you can provide individual feedback, or you can use the videos to free up time during lectures for discussions, repetition, or immersion.

Technical information

The studios are equipped with a laptop from which you can run your slides or other presentation material. Thus, you do not need to bring and spend time connecting your computer. The laptop is connected to a touchscreen that acts as a digital whiteboard, where you can, among other things, write and draw with the ChalkBox and, for example, annotate your presentations.

Webcasts are recorded in two tracks – also called Picture-in-Picture. This means that the shot of you in front of the touchscreen and the screen of the computer is being recorded separately. Thus, both tracks can be displayed side by side in the final video, and the viewer can decide how to display the video.

The sound is recorded using a microport kit. A microport kit consists of a lapel microphone connected to a transmitter and a receiver connected to the camera. It must be turned on and clipped on your clothes before recording.

A small remote control is attached to the computer from which the presentation is running. With it, you can remotely switch between your slides.

In the spring of 2019, the setup in the Navitas studio was updated, which means it is now possible to record in even higher resolution.

Lightboard studio

The lightboard studio was established through a collaboration between Media Lab and Jan Arlt from the Department of Physics and Astronomy. The studio is available for use to all educators at Science and Technology.

In addition to our studios with touchscreens, we also have a lightboard in our Campus studio.

A lightboard is a glass board where light is projected into the sides of the glass. The light makes everything you write on the glass become extra clear. This allows you to make advanced calculations without losing details. At the same time, you are facing the board and your audience, which makes it easier to write – the studio automatically mirrors the recordings so viewers can see what you are writing.

You can record yourself behind the lightboard while superimposing presentations on the screen. This allows you, for example, to annotate your presentations, add graphs, or other types of animations to your presentation, which you can annotate while you explain.

A detailed technical introduction to lightboard presentations can be found here. If you want to produce webcasts without the lightboard, you can find an introduction here.

Tips and tricks for better recordings

  • Prepare well.
    A five-minute video does not take only five minutes to record. Prepare your PowerPoint and talking points well.
  • Adjust your PowerPoints to the studio format.
    To avoid black bars on the presentation, we recommend you run PowerPoints in the 16:9 format instead of the 4:3 format. If you want to present PowerPoints on the lightboard, everything that is black will become transparent. Thus, make sure your text and illustrations are in white or other light colours.
  • Do not make your videos too long.
    A suitable length is about 5-10 minutes. If your videos are longer than that, you or your audience might lose focus.
  • Check your recordings every time.
    This ensures that nothing is missing. For example, you may forget to turn on the microphone.
  • Wait some seconds before you begin.
    Wait for 4-5 seconds after you press start before you begin speaking. This ensures that the video does not start in the middle of a sentence.
  • Practice before your presentation.
    If you use the drawing function on the touchscreen or want to annotate illustrations on the lightboard, you may want to practice this through a few times before filming. It is not difficult to do, but it may require a bit of practice.
  • Look at the camera.
    It can be tempting to look at yourself in the reference monitor; however, it offers the viewer a much better experience if you look directly at the camera lens. It may feel strange at first, but you will get used to it quickly.
  • Dress according to the presentation format.
    The walls in the studios are black. To avoid blending in with the background, it is a good idea not to wear black clothing. However, when using the lightboard, we recommend black clothing.
