I agree with Pablo.
My recommendation is to not stress too much about the video interview.
Through your application, INSEAD knows how you come across on paper. So the idea behind the video interview is simply to know how you come across in person. So, whether you answer from a professional or personal perspective doesn't really matter. Most questions don't have a right or wrong answer anyway. What really matters to INSEAD is the "soft" part of you, e.g. do you come across as someone who is confident, mature, introvert/extrovert... In a way, INSEAD is just trying to check whether the person in the videos is the same as the person in the application (e.g. essays, LoRs...).
I hope this helps.
Warm regards

Also if i'm asked to talk about an achievement, should it be on a professional note or i can say my family for example?
Thanks.
Hey, this is answered few messages above.
It is not clear, I would say that use the one you like the most for each question unless it is specified.
In the end, it is for them to know you as a person and you combine both.
