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.
Contents
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
