We have used TextIQ with some limited success on supporting qualitative analysis. What is your team trying to accomplish within the system? 

Well, Text IQ isn't really qualitative research; it's more of an analysis tool. I was thinking maybe about a feature like video response

My apologies I read qualitative research as analyzing qualitative data. You’re trying to collect video responses and analyze them specifically or was that just a “for example”? Our biggest experience with collecting qualitative data has been using free text information and feedback. We haven’t collected video feedback in any of our research or survey efforts yet on Qualtrics. 

The video/audio response will give you access to the video or audio recorded but also a video transcription that you could easily analyse with word clouds, text iQ, etc.

DXA (Digital Experience Analytics) might also be considered as qualitative as you can run UX tests for your participants to detect client’s behavior on your website.

Hope this helps !
