During the presentation by Dr. Laurent Filliettaz, excerpts of videos and transcripts from the videos were provided as examples of the data gathering and analysis of workplace based interactions between apprentice and trainer. From this, I could see that it would be important to have a way to bring transcripts and the video together in order to save time and multiple screenings. Therefore I had a look in the library for articles or books on video annotation.
An article by Rich & Hannatin (2009) in the Journal of Computing in Higher Education, 21 (2) caught my attention. This article reported on a project ‘ scaffolding video self-analysis discrepancies between preservice teachers’ perceived and actual instructional decision’ used a customised video analysis tool (VAT) to annotate the videos using a ‘commenting’ process to add speech bubbles to the videos.
The previous review of video analysis software shows that many of the tools are used in the sports areas and can be expensive when all we need to do in our project is to annotate the videos.
I then began an investigation into video annotation tools, as opposed to video analysis tools. nVivo provides for the facility to run a video and to have a transcript entry along with a blank column (for comments). I did the usual google search for ‘video annotation tool’ and came up with the following.
Anvil is a free for educational and research purposes and requires a email to the developers to obtain a copy. Seems to work very much like Audacity. Not sure if we will need all the bells and whistles but will email to obtain a copy to do a comparison with nVivo.
A simple video annotation tool might be the way to go if all we need to do is to put simple tags on the video.
Project pad provides a comprehensive tool with more information provided at open cast projects
So will need to follow up with trying things out on nVivo. As future iterations of the multimodal analysis project at CPIT will include collaboration with other polytechnics, I will also explore the use of Anvil and perhaps Transana, which has appeared on several research papers which require video data analysis (does cost small amount).

Video analysis software for multimodal data analysis
While browsing through literature on multi-modal analysis, I came across studiocode as a video data analysis software tool. I then asked around CPIT and found out the sports science people were using a NZ developed product called silicon coach which is developed specifically to analyse sports performances but also provides capabilities for comparison of individual performances and to build up resources based on annotations made on videos. Many video analysis software has a sports orientated slant as this is where it is most useful for analysing the performance of athletes.
I then did the usual google search and came up with a short article which recommended four video data analysis tools including studiocode (Mac OS only). The other three are annotation which is only Mac based but seemed to have an attractive, user friendly interface for US$299; ecove with a byline of software for gathering data while observing behaviour, runs also on Palm OS & Pocket PCs for US$189; & Observer xt which has both Mac & Windows versions plus a version for mobile devices, seems to have all the bells & whistles (like studiocode).
A comprehensive list of qualitative data analysis software provided over thirty examples with about a third capable of video and audio analysis. These include:-
Transana which is developed by the University of Wisconsin and open source and cost US$50 for single user and US$500 per project.
Dart fish which provides a free download trial for 30 days
Atlasti which is a standard qualitative data analysis provides for multimedia coding and supposed to be similar to nVivo.
Hyperresearch $399 as another alternative to the more expensive sports based video analysis tools.
A couple which are freeware to have a look at include Elan and signstream.
So plenty of choice for the moment, the most likely ones will need to be evaluated against nVivo. I am looking for one which will be easy to use as one of the goals of implementing multi-modal analysis protocols for observing teaching & learning at CPIT is to devolve the analysis to tutors.
