With a huge new interest in race videos, thanks to Cooper's slow-mo action, here is the process I used to make my Dusty Roads video...which is derived from what I was able to pick from Cooper. The tools were right in front of me, I just hadn't taken the effort to figure them out.
The key to the process is the iPhone. In particular, an iPhone with the slow-mo camera feature...which is the iPhone 5s and newer.
You can make slow-mo videos without the iPhone but the quality just isn't as good because the slow-mo is being done by third-party software on your computer. Recording with a slow-mo camera is always going to be better than artificial slow-mo from a program. But I'll address desktop software in a bit...
Using the iPhone
The only thing you need to install is the iMovie app, it's $5 in the App Store. I know that's kind of expensive for an app but it really is a easy-to-use app that makes video editing stress-free.
I was able to make my entire video using just iPhone. It was a tedious operation, mostly due to the size of the phone - way too small (and I even have a big iPhone 6). As far as I could tell, there isn't a way to easily transfer raw video from your iPhone to an iPad. Bummer.
Anyway...recording with slow-mo is easy, just turn it on and hit record...just like any other video.
After you've recorded a video, go into iMovie and create a new project to get started.
I'm not going to cover how to use iMovie. It's honestly pretty simple and trial-and-error is a better way to learn this type of thing. Just be prepare to try and try again.
Import your slow-mo movie. Trim it down to how you want, as well as adding any text and stuff...but you're doing it just for that race, not the "final" video.
After you've got it cut down the way you like, you need to export the movie. I just saved the produced movie into gallery - not to YouTube or anything like that - and was done.
We all know a tournament can be many, many races. However, rather than having one project where I imported every slow-mo video, I exported each slow-mo video on it's own. Then I created one final project and import each of the completed videos to make the final video that gets uploaded to YouTube.
So rather than put all your eggs in one basket, you put one egg in one basket until all your eggs are done. Only then do you dump all those eggs into one big basket for delivery.
I found this method easy to work with and manage rather than dealing with tons and tons of videos within a single project. It was easier to make changes and and focus.
Not using the iPhone
If you don't want to edit movies on your tiny little phone, using desktop software on your PC or laptop is the other option. If you do have an iPhone, you should still using the built-in slow-mo camera to record...it will result in a much better quality video.
But the trick is you must export the slow-mo video first, before transferring it to your computer. If you just drag-n-drop the movie file from your phone to your computer (like I first did), it won't come across as a slow-mo video, just a normal speed video.
After that, just use your software like you normally would.
The first videos I made was using desktop software and while it worked, the quality of the video coming out of the iPhone is just so much better, it's really night and day.
Slow and steady win the race
Editing videos is a slow and tedious process. I find it really boring but we've all seen that having a video adds a ton to the excitement of a race.
I would suggest rather than putting every single race/heat into your movie, just pick out the highlights. Find the races that were closest or biggest upset or whatever...your choice. Not only will this require less editing time, but it will make it easier for viewers to digest. Few will watch 30-minutes of racing. If you can keep it under 5-minutes, you're good.
One other thing to consider when making videos is lighting...lighting, lighting, lighting. If you invest in anything other than the $5 phone app, buy some lights. Or at least some daylight bulbs for your lamps around your track. You might have an awesome track and make an awesome video, but if the lighting is shotty and otherwise dark, it's hard to see the true action.
So that's how I make my videos. What do you use to make yours?
