@burke9119 I’ve moved your topic to #ask-the-community for now, as explained below.
With regard fine tuning the timeline, if you use a pinch-out gesture, the timeline will zoom in and give you much finer control. Please see if that works for you. There are < and > buttons on the ends of the timeline that will let you jump to the previous/next segment.
If you still want start/stop buttons, please submit that as a single standalone #roadmap request.
There is already a 12/24 hour option request in #roadmap: Timestamp 12- and 24-hour time formats. Please add your comments specifically about the timeline there.
There is already a mark events topic in #roadmap: Mark Events In Playback
Please submit the direct time entry as a separate standalone request.
Ditto for the video repeat feature.
For future reference, please search the #roadmap topic before submitting and try to keep submissions to a single subject/request.
