Note on USB Connectivity
A lot of the devices listed below require a USB-A port. Some devices such as new Apple MacBooks may only have the newer USB-C type port, for which you will need to buy an adaptor. iPads have the proprietary Apple Lightning connector, so may also need an adaptor to connect to USB devices.
Capturing better video
Choosing a Camera
Existing laptop camera (will likely either be HD720p or HD1080p)
Peripheral USB HD Webcam such as a Logitech HD cam
Thinking about Light
...
If you are having to record at night, or in a room that does not have enough natural light then we recommend the below:
A ring light such as this
A webcam with integrated lighting such as this
In lieu of the above, a well positioned desk or standing lamp will suffice, just remember to carefully consider positioning in line with the recommendations above.
Capturing better sound
Microphone
If a student has to watch a lot of recordings across their different courses, then ensuring good audio quality is very important. Audio that sounds ‘okay’ on playback may be fine over short periods but will be fatiguing over longer recordings. Thus it is important to really focus on good quality audio.
...
Lavalier microphone (wired clip-on lapel microphone, similar to those found in teaching rooms). DTS have tested this mic and for £23 are very happy with the results.
USB podcast/streaming condenser microphone such as this one
Sound Recording Tips
When recording, try not to touch the microphone as this handling noise will be captured on the recording. Be careful of any loose clothing or long hair that may come into contact with the microphone while recording as, again, this will be captured.
When positioning the microphone you want to be close enough to capture a good clear audio signal, but not so close that you overload the microphone. Plosives (as in the phrase “peas popping”) and sibilants (as in the phrase “sizzling sausages”) are most likely to cause problems as they create sudden big movements of air and so jumps in volume; record a practice phrase to check these sounds and that you are not too close.
If wearing a clip-on lavalier type microphone, position the capsule a short distance below your chin(where a shirt pocket would typically be) and with the capsule facing downwards towards the floor. Though counterintuitive, this will mean a good signal level and avoid any problem plosives or sibilants from negatively affecting your recording.
Before you start recording, consider your environment and any noise there might be (nearby building works, air conditioning, traffic noise, TV, washing machine etc.). How could these be avoided (e.g. record at different time, switching off electrical items etc.)
