Many a time we may like to keep our or other privacy while creating a video, especially when the video is going to be posted on the internet or be sent to people unknown not simply who cannot be trusted.
The best option in this case would be take a video appropriately while hiding any personally identifiable thing. Obviously it may not be always possible, so the other alternative might be to just edit the video. If the video is edited to completely remove the portion it may seems obvious or you might have to miss showing some other important thing. So the best thing to do would be to simply blur the unwanted area.
