I don't agree on Mad Max. (In my few) It's obviously center-framed because of eye-scanning. With all the cuts and explosive action, it would be tiering and hard to follow if the action would switch sides of the frame.

But maybe that is an obvious matter for others?

2. keep some extra cameras with you.
3. Keep it steady.
4. good shoes.. (some want you to dress more classy, but I always use comfortable shoes. Like running shoes)

I've done wedding videos, in which I have filmed the whole event. (1 to 3 days)
I then edit it down to like 2-3 hours. There are a lot of speeches and dancing. And the actual wedding. I use a lot of music between speeches and often end the video with a nice look-back at the wedding and past shots. I often don't use to much editing and music. In my case, I think they're more interested in the speeches.

1. keep an eye on the wedding photographer.

I've always been interested in changing the color of the wardrobe throughout a film.
A color can tell something about the character. If it's blue or green, it will or can stand as the color of the character.

A simple example,
a character loves writing books. And in the scenes the character writes and loves it, he's dressed in red.
Then he get's in an accident. He wears the white robe when in the hospital. When eventually he get's home, he's wearing black. He can't write books. (Because of reasons)
As the film goes, he will eventually get back on his feat and finds himself. He now wears green. Recovery.

Presenting a color when presenting the character at a certain emotional state. And yes, I presented a very bad example. But I hope I got my point crossed.
Thanks.
