Thanks for posting. Unfortunately Spanish is not my primary language so I’ll reply in English:
Your question is whether it is possible to use Videosync in Arrangement view since it doesn’t disappear like Ableton’s native video window when closing a set.
Ableton does not yet expose Arrangement view information to third parties, so we are unable to use it in Videosync. As soon as this information is added to the Live API, we’ll be happy to support it.
Until then I’m afraid the only option to use Videosync would be to change your performance to the Session view, and do something like triggering scenes sequentially, but I can imagine that is not viable for you.
