Saw a cute idea on youtube what do you think

It is very pretty. I would have a few concerns though. Will your guests actually be listening to what is said if they are watching the bridal party walk down the aisle? How long would you make the letter because unless you have a huge bridal party it doesn't take that long for the bridal party to walk done the aisle? Without music will the bridal party properly pace themselves walking down the aisle? I know our bridal party had a difficult pacing themselves at our rehearsal because there was no music for them to practice so they weren't sure how quickly to walk.
