We use jitsi / jibri for usability studies.
We ask participants to try out our prototypes, while the session is screencast and recorded.
It would be helpful if one could set markers or bookmarks in the video, e.g. when the participants performs an unexpected action. The experiment should not be interrupted, so bookmarking the moment and asking the participant after the experiment for her/his motivation would be ideal.
The manual workaround is sitting aside with a stopwatch, starting when the recording starts and noting down the time by hand.
Does such a feature already exist?
Could the mp4 ‘chapter’ feature used for this?
Imagine a button ‘add bookmark’ shown only when recording is active and for moderators of the room, that simply adds a new chapter 1, chapter 2 … everytime it is clicked.
