Let’s say someone sends you a video to watch. How long can said video be before you decide it’s too long to watch?
For the purpose of this question, let’s assume you’re trying to decide whether to watch it or not right when you receive it. Let’s also assume that it’s moderately interesting (5/10).
If we are in a voice call I will never watch anything anyone sends to me immediately because they are going to continue talking over it anyway.
If the video is something I am genuinely interested in I will watch it regardless of length, otherwise 5 to 7 minutes is my max range.
