First, let's talk about money since its one of the primary factors in choosing a videographer. A lot of videographers don't post their prices because they want a chance to negotiate with you. Usually they'll start ridiculously high and see how you react, then negotiate down from there, which usually makes you feel like your getting a good deal. My advice is to go into a situation like that with a little caution. We proudly post our prices, for example, because we treat everyone equally and don't waste time with the negotiation dance.
Another basic expectation is for the videographer to ask what aspects of your wedding are especially important to you. This is the starting point of any professional editor! It's a basic question ask, and if they're not asking it, they are assuming the responsibility of deciding for you. We always ask before and after the wedding. It's important to discuss these points before the edit begins, because once it starts, there are no re-edits. Unless there are major flaws, most videographers do not allow changes without a cost. This makes sense, since most editors work at around $40 an hour. If the bride and groom kept asking for edits no one would be able to afford a wedding video. Manoa Productions doesn't run into these issues because we always have a good sense of what the bride and groom want.
Lastly, the most important thing to do is to ask for sample videos. Don't confuse this with highlight videos posted online, because they only contain the good parts. Ask for full example videos, not necessarily to watch them all the way through, but just to get a feel of how your video would turn out. When we meet the couple we always offer to watch of few full versions.
