Data collection

This is a page to add advice about specific guides for data recording, equipment and collection based on a document circulated by Ruth Parry: Conversation analysis and Clinical Encounters Conference York 2013 Report from a Knowledge sharing workshop: Tools, techniques, tips, processes, software, hardware.

What's on your packing list?

• Camera(s)
• SD flash memory cards (SDHD = high capacity SD)
• Camera clamp/pole/tripod etc.
• Wide angle lens
• Mic(s)
• Mic stand
• Digital voice recorder for back up
• Headphones
• Bulldog clips, duct tape
• Spare batteries
• Consent forms, record forms

Camera(s)

Things to consider when selecting cameras:

• Bring one or more cameras?
• External power supply? (ideally don't run them on batteries)
• Fish eye / wide angle lens recommended
• Headphone jack for monitoring audio recording?
• External mic jack?
• Remote on/off control can be useful
• Lens cap you can put on to record sound only

Camera Storage media

• Don't go for direct to DVD (they are trouble!)
• Go for high definition + records onto SD card
• They tend to record to their own proprietary formats
• JVC records to an MPEG4 which houses an MPEG2, Canon records to MTS files
• They all need converting (encoding) into a format you can play, edit, and that works with your analysis software
• CLAN, ELAN (?transana) work well with MPEG2

Other camera ideas

• Camera you can turn into a player that projects onto the wall (show participants straight away)
• Eg. Sony

Camera recommendations / notes

• Canon Legria / VIXIA HF G25: http://www.canon.co.uk/For_Home/Product_Finder/Camcorders/High_Definition_HD/LEGRIA_HF_R406/
  • Canon LEGRIA (EU) are sold as VIXIA in the USA
  • For this camera you will need a wide angle lens for adequate capture in most environments: Canon make one, but it is expensive. A good compromise is the following, which is good quality Helder MW-4558 58mm HD 0.45x Wide Angle Conversion Lens: http://www.bhphotovideo.com/c/product/758310-REG/Helder_mw_4558_Wide_Angle_Lens_Converter.html
  • Possibly hard to find now: Canon Legria JF S200: http://www.canon.co.uk/For_Home/Product_Finder/Camcorders/High_Definition_HD/LEGRIA_HF_S200/
  • The Canons have default sound settings not ideal for our kind of work, so you MUST follow this tutorial from ‘UKAirscape’ if you want good sound https://www.youtube.com/watch?v=XVHNe-6runQ
