I record live wildlife webcams for long periods and am using a different screen-capture program which allows me to add current date/time (and any copyright info, as appropriate), for example:
Even if text was not possible, the timeline would be invaluable because it helps massively when cutting and joining clips from these long recordings, as well as verifying the date and time of whatever action/s I'm showing.
I would like to use Bandicam because I like its recording quality, both vision and sound, but I do need the timeline at least.
