If I have good bloopers, I usually will include them. Bloopers might not be appropriate if the video concerns a funeral or a very serious subject. Let common sense rule.
With that said, here is a tip – the audience usually will not remember how the music started but they will remember when it ends. When I have music that is slightly longer than the clip or event that I’m supporting with music, I line up the end of the music with the end of the clip or event. I then fade in the music at the beginning of the clip.
