  1. Visual Analysis and Software Assistance Dr. Christine Rivers QUIC Project (NCRM) University of Surrey

  2. Rationale • PhD Project - Experiments • Remote Tabletop Collaboration • Gained Different Multimedia Data Sets • Unsynchronised files • Merging different Data Types • Which software allows synchronising and analysing in-depth?

  3. Questions • Which software is useful? • How can we analyse effectively?

  4. Overview • Criteria for: Which software is useful? • Comparison • Atlas.ti 6 • Transana 2.41 • DRS (Digital Replay System) • Conclusion

  5. Which software is useful? • Type of Data – Multiple Multimedia Files • Synchronisation • Preparation of Data • Analysing Data • Extracting Sequences in-depth Analysis • Coding Schemes

  6. Atlas.ti 6 • Compatible with Windows/ Vista/ Mac BootCamp • Text files: txt, rtf, doc, pdf • Multimedia files: jpg, jpeg, gif, bmp, wav, avi, mpg, mpeg, mp3 • Synchronisation of Transcript & Video using F4 • Synchronisation of Multiple Videos not supported • Requires Preparation if Multiple Data Files used

  7. F4media

  8. F4media • Allows Transcribing and Editing Existing Transcripts in relation to a Video File • Synchronise Transcript and Video for Use in ATLAS.ti • Requires Preparation of Videos • Particularly Multiple Videos • Video Quality poor but less important for Transcription

  9. F4 Docs in ATLAS.ti

  10. Windows in Atlas.ti

  11. Quotation Manager

  12. Code Manager

  13. Memo Manager

  14. Summary ATLAS.ti • Advantages • Initial / Open Coding • Identifying Themes • Linking several codes to 1 quotation • Data (Video or Audio) can be synchronized with a transcript using F4 but difficult • Disadvantages • Data has to be prepared • Detailed Analysis difficult

  15. Transana 2.41 • Compatible with Windows/ Mac • Multimedia files: wav, avi, mpeg-1, mpeg-2, mp3, rtf • Does not support multimedia files from CD or DVD or still images • Video and Transcript(s) can be analysed together - Interactivity • Video Data requires Preparation

  16. Windows in Transana

  17. Video Window

  18. Transcript Window

  19. Data WindowAdding an Episode (Video)

  20. Synchronizing Visual Data

  21. Producing Clips for Coding

  22. Viewing Clips

  23. Coding by Keywords

  24. Summary of Transana • Advantages • Importing Data of Different Types easy (e.g. ATLAS.ti F4) • Having Multiple Transcripts and Video Files in one • Extracting Clips and coding individually • Disadvantages • Videos have to be prepared • No still images

  25. DRS (Digital Replay System) • Compatible with Windows / Mac OSX 10.4 • Multimedia files: wav, avi, mpeg-1, mpeg-2, mp3, rtf and jpg, png, gif. • Video and Transcript(s) can be analysed together - Interactivity • Video Data requires Preparation similar to Transana (Synchronization Issues)

  26. Windows in DRS

  27. Video Window

  28. Project & Analysis Browser

  29. Analysis Browser

  30. Analysis Browser

  31. Transcript Window Time Codes

  32. Track Viewer

  33. Coding in DRS

  34. Moving & Adding Codes

  35. Summary of DRS • Advantages • View multiple media files synchronously (video, transcripts etc.) • Coding is easy to do • Adding and Importing files easy • Disadvantages • In-depth analysis produces a lot of ‘windows’ • Codes can not overlap in one track • Video quality is poor even if prepared

  36. Conclusion • Each CAQDAS tool offers good solutions • Depending on type of data • Amount of data • Level of analysis that want to be achieved

  37. Suggestions • Synchronization • Preparing the media files before using them in one of the CAQDAS tools • Transcription • Transcribing directly in the CAQDAS tool is beneficial as data can be directly related to media file
