bat-mitzvah montage

Not exactly a Jewish question, but apparently Jewish-adjacent nowadays:

My daughter’s bat-mitzvah is in two weekends (yikes!). Nowadays there are big screens everywhere at b’nei-mitzvah venues, and my daughters is expecting a photo/video montage at the beginning of the reception. Those who’ve put these together: how many photos/videos did you include, and how long was your montage altogether? Five minutes seems reasonable, no?
