I've had a look at Transana and it is very interesting. However it seems
more in the league of NVivo than Qualrus because it requires transcription
rather than allowing direct coding of raw video files.
What is unique to Transana is that it allows segments of transcript to be
linked to corresponding segments of video; an interesting and potentially
powerful feature, especially for presentation or collaborative work. I will
certainly investigate it further.
For me the great thing about Qualrus is sidestepping the need to transcribe
at all. The problem with transcribing is the time it takes, the loss of data
richness and the typos. However it takes some time to get used to working
directly with video (or audio) data, and colleagues often prefer a
(hardcopy) transcript for sharing data/meetings/presentations etc.
