Thank you so much for your support and suggestions. This is very much appreciated!
In general all suggested options would/could work. But they have nevertheless a realistic chance to end up in a video playback which is interrupted in somewhere within the playback time. Usually it takes some few seconds (depending from bandwidth, location, display,…) until the video really starts. This means, when I have a 1min video it will be cutted at the very end for let’s say 1-2 seconds. If I have a 45 second video in a 1min priority schedule, it will run twice - once full and the second cutted after aproximately 15seconds.
Sure, I can work around all this by defining propper video length with some “flexible” time at the end so that a “cutted” video isn’t recognized by the audience. Nevertheless it would be more convenient and flexible to have this play-count option as it was already taken into concideration by Dan in Feb 2018 (Scheduling question).
