If you are looking to film a video, you do have to be careful about the process as it can be a bit complicated than you might think. There are not too many things that you have to do when filming a wedding, however, the more careful you are, the better it is going to be. This is the part where most people make mistakes and end up messing up their projects.
Keeping that aside, I would suggest you head to the professionals, or at least see their guide here to have a better understanding as to what is the right thing and what is not. As for now, we are focusing more on some of the things that you should take care of before filming a wedding.
Make Sure Everything is Ready
The first thing that I suggest to everyone is making sure that the equipment is ready. Not just the cameras, but everything else as well. You do not want to have any unprepared stuff that is only going to delay the process or make it not as good. If you are getting paid, you have to give your level best, something that everyone should keep in mind.
Always Have Backup
Another thing that I always suggest everyone is that they should always have a backup. This applies to both the equipment, as well as the crew. You do not want to arrive at the menu half prepared because then it will just look like an effort that is not done completely.
That is why people hire videographers in advance so they know how to arrive at the venue, and how to make sure that they reach the venue with everything with them.
