Essential Info

This page provides important advice to help you produce the best quality podcasts for your students.


Podcasting for Semester 1 2020/21 courses

Information on how Podcasting can be used in Semester 1 of 2020/21 courses can be found on the Using podcasts in Semester 1 teaching for 2020/21 courses page.

What is recorded?

By default the Podcasting Service records the output of the projector, which might include Powerpoint presentations, document cameras, PCs, tablets, mobiles and other media (depending upon what is sent to the projector).

From September 2017 onwards 30 lecture theatres were equipped with video cameras which can record in addition to, or instead of, the projector output. The use of cameras is voluntary and must be selected to be used by teaching staff on their opt-out web page. When a video camera is recording, three red lights will appear around the camera base to show that it is in use. See the camera page for more details.

External/guest speakers

If a guest/external speaker will be delivering lectures as part of a taught course unit – you need to ensure that they are provided, and complete, a consent form – which you should then store for your records.

In larger lecture theatres there are wireless (also known as lapel or radio) microphones which will provide the best quality audio for the podcasts if they are used correctly.Before the lecture begins you should ensure that the microphone is not muted or switched off –  there is usually a mute button/switch located at the top of the wireless microphone unit.

In smaller theatres we have provided additional microphones on the lectern which connect directly to the podcast system. In the recently refurbished lecture theatres, there is a switch on the LCD control panel to turn the microphone on – please ensure that it is on before you begin your class.

The use of microphones is covered by the following policy, see section 4.4: Policy on Inclusive Teaching and Learning Materials.

The pictures below show the two different types of microphones and the control panel switch.

Projector Screens

Some teaching spaces are equipped with more than one projector. In these areas we have chosen to record whatever is displayed on the right-hand projector as you face the board if there are two screens, and the central screen if there are three projectors, as highlighted in by the green boxes in the images below. Please note that regardless of disabling a projector any content displayed on the theatre monitor may still be recorded.

Important note: the audio/video system setup in some locations means that we do not record what is displayed on the right screen; instead whichever input is selected last is what is recorded by the podcast system. This applies to: Mansfield Cooper G.22, Sackville Street C53, and Zochonis Theatre A.
If you are teaching in any of these locations, please be aware that you need to press either lectern PC, laptop or visualiser last, depending upon which one you want recorded.

In Schuster Blackett and Bragg – it is the last displayed input which is recorded by the Podcasting system, therefore you will need to ensure that whichever input you require to be recorded is what you display last.


If you wish to record output from the visualiser you will need to ensure that you switch between the relevant inputs – i.e. what is being shown on the screen that is being recorded, is what the system will capture – as only one input signal is recorded.

Using the Pause QR code to pause/resume recordings

Pause QR Code - displayed to pause live recordings

The podcasting system can detect a specific QR code which, if correctly displayed, allows the recording to be paused. Click on the image to the right to download the QR code (if the image displays in the browser rather than downloads, right-click on it and choose “save as”).

We recommend you display the Pause QR code at the beginning and end of your lectures, and during any breaks, in order to ensure that only teaching content is recorded. Using the QR code in this way can also prevent the need to further edit the podcasts.

In non-video camera locations – when the QR code is used, the system automatically pauses the recording for as long as the QR code is displayed and resumes once it is no longer shown. Note that using the QR code to pause recordings will also remove content for any DASS students on the course and should only be used when appropriate, for example when there is a break during a lecture, or before the lecture begins.

In video camera locations – only if the video camera is used – rather than pausing the actual recording in real-time, when the QR code is displayed its timings are stored in an edit file, which is then used to remove those sections when the recording is being processed. The original, unedited recording is stored by the system so if it is recalled for editing – the full, unedited version will be available to edit.

Further details on the Pause QR code can be found on the Pause QR Code FAQ page.

Macs and screen recording problems

If you are using a Macbook to connect to the projector in the room, please DO NOT USE THE HDMI CONNECTION as this will cause issues with the recording as it enables High-bandwidth Digital Content Protection (HDCP) – which prevents the podcasting system from capturing the display. If you use a HDMI connection, the podcast video will appear as either green or static video.

To avoid this issue, use a VGA cable to connect to the projector, as shown below.

Solstice Pods

In some locations technology called Solstice has been installed and this allows you to connect and project your device over Wi-Fi. If a location has a solstice pod installed, it is recommended that macbooks are connected using this to prevent HDCP issues.

Details of the system can be found on the following site:
