Capturing and editing audio and video
Hardware
Equipment for recording video:
- Smartphones (+ additional lenses if desired - largely catering for iPhone/iPad users but some Android compatible hardware is avialable). Clive Young has posted about using smartphones for video/audio on the ELE blog.
- DSLRs (Digital Single Lens Reflex) - ostensibly stills cameras, these often include video functionality. For talking head clips a prime - or 'pancake' - lens can be useful in blurring out background and fixing your subject in precise focus (this blurring is known as bokeh). Engineering & MS&I are both using Canon EOS700D DSLRs with a Canon 40mm f/2.8 prime lens. (If you're a member of Engineering staff you can request equipment loans via this form).
- If using a DSLR for video (especially outdoors in bright conditions) it can be useful to attach a loupe. These detachable viewfinders allow for better perception of composition/focus and circumvent troublesome LCD glare issues.
- iPads and Android tablets
- Kodak Playfull Waterproof Video Camera (UCL STEaPP are using a couple of these)
- A tripod. You don't necessarily need a huge, expensive piece of kit:Â eg Joby make a range of flexible, gripping tripods for numerous devices - including telephones & tablets.
- Laptops and desktop computers for screen captures and web cam recordings.
- Webcam - built in to laptops, smart phones, or external for desktop computers.
Equipment for recording audio:
- Smartphones (iPhone & iPad owners are able to buy additional 'professional quality' microphones such as the Tascam im2/im2x)
- Tablets
- Dedicated handheld hardware recorder (range in price from ~£50 - £1000s)
- Laptop with built-in microphone
- Laptop/desktop with external microphone (eg Engineering has a Samson USB microphone). If you need to be able to move around, USB clip-mics (eg Revolabs xTag USB) are also available and, again, vary in cost. (The Revolabs set costs ~£200).
Software
For free audio conversion software for PC and Mac see:Â http://blogs.ucl.ac.uk/ele/2015/03/16/need-to-convert-wav-files-to-mp3/
Video
Cross-platform:
- For video, voice, screen capture and streaming, Open Broadcaster Multiplatform is open source and straightforward to use (see this quick screencast introduction from Feb 2016).
- www.screencastify.com - a chrome plugin that records free 10 minute videos of Internet applications (can be saved as wmv files) with a screencastify logo in the top, right corner.
Not recommended:
- Filmora is easy to use, but the watermark goes right across the bulk of the lower 3rd of the screen, so is unsuitable for video capture unless you buy a license.
Audio
Cross-platform:
- Audacity - free cross-platform audio editor and multitrack recorder.
Free options for recording audio on a Mac:
- Audacity - free cross-platform audio editor and multitrack recorder.
- Soundflower with Audacity configured to capture the output of the Skype call:** http://www.wikihow.com/Record-Skype-Into-Garageband-With-SoundFlower-and-LineIn
- Soundflower with GarageBand** http://www.wikihow.com/Record-Skype-Into-Garageband-With-SoundFlower-and-LineIn
- QuickTime Player on Mountain Lion.
File > New Audio Recording.
It records your voice and the sound coming out of the computer, be it Skype or whatever. (http://www.youtube.com/watch?v=nqfog_Ve5Rc) ****** recommended! QuickTime Player is simple to use and it just works - it’s 1 channel recording though, meaning each person on the phone call comes through on the same track.
Free options for recording audio on a PC:
- Audacity - free cross-platform audio editor and multitrack recorder.
- Windows Sound Recorder - is a very basic recording application built into Windows that captures mic/line input.
- Soundleech -Â
- Total Recorder -Â
For either of these options to be able to capture a Windows computer's native sound output (eg Skype, Youtube videos etc  - not external audio such as a microphone) the soundcard will need to be configured accordingly. Windows soundcards vary from machine to machine, but a fairly comprehensive set of instructions for configuring them can be found on a dedicated Audacity hardware configuration page.
Options for recording Skype calls on a PC:
