This page provides important advice to help you produce the best quality podcasts for your students.
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.
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 pictures below show the two different types of microphones and the control panel switch.
The use of microphones is covered by the following policy, see section 4.4: Policy on Inclusive Teaching and Learning Materials.
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, Schuster Theatres: Blackett, Bragg and Moseley, 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.
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.
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.
