I currently make heavy use of frame links with video and audio files. I use DT for history/sociology research, so my tasks revolve around making RTF files for topics, and then I use links to video, audio, and PDF’s to group all the relevant instances for that topic.
I do also make videos, but once I get to that part of my process, I just use timestamps or the DaVinci Resolve transcripts to get to the relevant video/audio sections.
