How many of you have seen a UAP but when trying to film it – nothing is evident/visible in the replay?

Hello everyone. Many people studying the phenomenon (e.g. Jacques Vallée/Gary Nolan/Karla Turner) have stated that an aspect of the phenomenon exists in one’s individual consciousness. There are stories of individuals/couples seeing UFO’s but the people around them don’t seem to notice or at least, it wishes not to appear to them. Since most of the posts in the sub are what we would call ‘physical’ sightings – I wanted to ask the community if they ever experienced such a phenomena but when trying to ‘record’ it somehow (could be camera, could be assurance from others) nothing is overtly visible? Thank you.
