I am doing a video recording for a powerpoint presentation, and sometimes I have some seconds of (idleness) during the recording (where there is no change in the presentation nor speaking audio). For user experience reasons, I prefer to remove all such parts that are longer than 1 second (to keep the video engaging).
I am currently doing this in a manual way, but it is an extremely time-consuming process.
I was thinking if there is a way to automatically (using a tool or a filter or so) remove such parts in the video.
