Camera angle variety. That's not to say going ham with senseless angles will make it better either. The more control the game allows you to have with camera, the more you can do. If not, then that's too bad really.
Music on the other hand... this one is
very subjective, but I would aim for music that fits the tempo and mood of the video content. It doesn't fit well to have high tempo music with slow movement and vice-versa. You can either compliment the mood of the video or, if you're good at it, you can manipulate the watcher's mood when watching without detracting from their engagement and/or enjoyment. Highly subjective stuff like I said, but it can be done. Some people nail this very well intentionally and some by sheer luck.
Here are some racing game videos I made where I put the time into arranging external music. While I get that we all perceive art differently, let me go through my thought process and perhaps you may find some of it useful. Try to feel out how the music works with the engine noise. I'd be interested to hear what you think about it.
1) I open the video with an over-stretched intro with recorded footage of the camera panning over the car and scenery slowly. I matched this with a mellow beat.
2) During the run, I ran a high-energy rock track. You might notice I didn't run the track until the approach of the first turn. I chose not to because to me the excitement of driving in a racing game is when you reach the first corner- the first game-changer in the course. This would create a sudden excitement by pushing all the elements of tension in at the same time.
Why did I choose rock? Rally driving... wild driving... aggressive music. I wanted to use it as an enhancer rather than simply an additional set of sounds that compete for attention. The video is still about the car and the adrenaline car noises create, so this is why I kept the music volume lower.
By the end of the race, I think I did a hack job at transitioning to another part of the same track, but the reason for that will be explained later. The point was to signal a change of scenes at an audible level. I don't know how effective that really is, I'm not a composer, but I thought it may have some worth. the same kind of energy continues on throughout the replay. I have nothing to say about the camera angles as I did not do anything there. The game changes the camera angles on its own.
By the end of the replay, the song slows down and we move into the credits. I had moved the music track around in the video editor to match the video track like that. For the same reason as before, it's to indicate a change of pace.
When you're not composing your own music, the music won't always line up to what you have in your video content. I think I arranged the outtakes to time a good ending for when I cut the music. There was still more to the song but the video was coming to an end, and it'd be a clear sign of laziness to not put any thought into how I can end the audio in a video. In one of my outtakes, I crashed the car into a tree. The idea came to me that I could cut the music at the same time as if I wrecked the radio in the car.
I know rock tends to be the one of the more popular choices of BGM for driving, so this was one where I experimented with jazz. The event's called "Wild Ride", so I that was one theme I tried to match. Here I moved the music track so the race ends with the piano bit. The sax playing throughout the drive was all bonus.
Here's a police chase. I wanted action, something to heighten the thrill of a getaway. I chose an orchestra piece from a Sci-Fi/Action show. The music once again does not start at the beginning. There's no tension or the slightest bit of urgency a this time. The music starts playing we are introduced to the interceptor Corvette, but the track is heard the moment I blow through the first roadblock. Same concept as the one in DiRT3.
If you haven't played this game before, when you use a Turbo or Jammer, it cuts out all game music. I did the same thing hear to match that. I felt it would decrease the intensity of the turbo if the music played the exact same way at normal speeds, so decreasing the volume would create the illusion that we're traveling
super fast.
The energy raises towards the end like a climax. I think I moved the music around to match that ending before
and after
the finish line. I think the music playing at the beginning with the roadblock collision was a complete coincidence. But whatever, it worked!
