Most people don’t have both and therefore expect the MOH to do things like handling the bouquet and helping with garments (like if the veil or dress get caught up.) And in general people pick their bridal party because they are people they want to be paying close attention, focused on, and participating in the live event. So people just need to realize that if they ask a member of the bridal party to film, that is now that person’s ‘job’/role for the duration of the time they are meant to be filming. It isn’t fair to ask someone to film and then, for example, be cranky because you didn’t feel like they were ‘present’ enough with you or that they missed a cue to help with/do something else. (General you.) That was my point. If it’s important enough to ask someone to film, people need to then recognize that a person taking that task seriously is going to prioritize that over other things, because it’s not like you can just redo it all if the filming doesn’t work out.

Also, if it is important, people should keep in mind that often the best place to film from will not be where the bridal party typically stands, as they are usually put off to either side. To get a good view of the relevant parties, the person filming will likely want to move (this should be scouted out during the rehearsal) which means in photos they won’t be lined up all neatly and symmetrically because one of them will be positioned for filming, not for looking nice in photos. I’m not saying symmetry in photos SHOULD be important, just that to some people it is and those people should consider that when deciding who will film things.

Finally, for anyone planning to do filming themselves (however they do it): there is no such thing as too much battery life or storage space. Calculate how much you think you’ll need then make sure you have a lot extra. It is MUCH better to be in a position of not having to worry about wasting or running out of battery or storage space when deciding what and when to film. Because if you’re limited, it’s pretty much guaranteed that you will then run out at the worst possible moment, because Murphy’s Law. (For battery in particular, if someone is just using a smartphone - which have pretty decent cameras these days - there are some pretty good battery packs you can get now for not too much money, and that’s worth it. Heck, if your filming person likes to do filming/photography with their phone in general, it’s a great gift.)
