My typical trail video is around three minutes long. I keep it short so you can quickly learn what the trail is like. I'll shoot 50 to 80 scenes on the trail, which adds two to three hours to the riding time. I mix point-of-view with trailside, overhead, and ground shots. This multi-camera technique tells you a lot more about the trail than the usual endless "look down the trail" shots. So I ride with 5 video cameras. Then in the video editor, I cut each clip down to just a few seconds each. My goal is not just to avoid boredom -- it's to show you as much of the trail as I can. Editing takes 4 to 6 hours.

That's me in the year 2000, with a heavy camcorder bolted to the top of my helmet. Filming was hard work when compared to today's video technology.

Point-of-view trail footage, through-the-wheel shots,  and scenes of zipping past the flowers and cactus.

The Point-of-View shot is the workhorse of mountain bike videography. The Karma smooths out the bumps. I try to limit this classic GoPro footage to less than 10 seconds at a time. While mostly used for down-the-trail views as I'm riding, I also take the gimbel off the chest mount to shoot special-interest shots -- such as a view of the wheel as the bike rolls along the trail. I avoid having any point-of-view shot fade into a second point-of-view scene. There must be a clip from another camera between GoPro sessions.

Overhead shots, ride-along shots, distance shots that show the terrain.

The drone adds considerable visual interest to a biking video. While I really like shots where the drone flies along close to me, these often aren't possible due to the terrain of the trail. (The software can't track me if there are lots of very dark objects like junipers, dark boulders, or harsh shadows. Or it can fly straight into a tree while "watching" me.) "Moon dust" or fresh snow on the trail, or gusty wind, may make it impossible to launch or land the drone. Drone shots may be long or short, depending on the visual interest.
PS - the cell phone is not only part of the drone-controller, it doubles as a 6th camera to shoot photos for the trail web page.

Natural-perspective shots as the rider comes past the camera.

In this case, an adapter allows a GoPro mount to snap onto the top of the tripod. The various knobs allow me to adjust the camera's tilt where the terrain is so uneven that the tripod can't compensate. I usually shoot an approach shot and a ride-away shot, then stitch them together in the final video. The total time for a ride-by is usually only around 4 seconds. That's why it takes so many scenes to make a movie.

The camera rides inside its clear case, stuffed inside a fluffy sock in the gear-net of my backpack. When I set up, I snap the mount onto the tripod. It's a compromise between protecting the camera and avoiding time spent fiddling with gear.

Low-angle ride-by shots, wider-angle scenes on turns and structures.

Many scenes need a bit wider angle of view to get more of the surroundings -- and more of the biker -- into the frame. For example, sometimes I want to show myself riding all the way around a hairpin turn, but the trees won't let me move a natural-angle camera back far enough. This camera setup is also great for low-angle ride-by scenes. I stuff this whole assembly inside a fluffy sock, and it sits in a quick-access net on the back of my backpack.
Q: Why use separate cameras?
A:  So I don't have to mess with changing settings on the trail. Ride time is limited. And, in bright sunlight it may be impossible to read the LCD displays correctly.

Jump-overs, ride-bys in tech terrain, extreme wide-angle shots, dirt ride-bys.

This great little camera endures a lot of abuse. It's my "dirt camera." I put it on the ground, then grind it into the dirt or prop it up with pebbles to set the angle of the shot. Then I turn it on, ride away and come back flying past the camera. If you see a shot of my tire going straight over top of the camera, it's this one. I destroyed three lenses during 2017 when the camera (1) fell over onto rocks in a high wind, (2) was accidentally smooshed by a bike tire, and (3) was bashed when my cleat slipped and I fell down a smallish cliff while setting up a shot. These "view upward from the dirt" wide-angle shots add a lot of visual interest to a video. The typical scene is 1.5 seconds riding toward and 1 second riding away.

The GoPro and Karma stay on my chest for the entire ride. When not filming, I pull a half-sock over the camera to protect it from dust and sweat.

Everything else goes into this huge CamelBak. When shooting a scene, I stash the big backpack behind a bush so it won't show up in the video. Because I'll be out on trail for two extra hours, I need extra food and fluids. So making a video adds about 15 pounds of weight to my ride. 

Back-and-forth riding to get the scenes makes the ride a couple of miles longer. With around 40 sprints to get up to speed for the ride-by scenes, and I usually come home totally trashed. It's a lot of work to make a video -- the way I do it.

Graphics and titles are easy to stylize, size, position, and fade in-out in this software. And although the selection of free music is limited, Adobe will analyze any clip you give it and re-mix the music so it fits your movie length.

My typical riding video is 3 to 5 minutes. I'll spend about 4 hours cutting clips, setting transitions, adding titles, plus adjusting the gamma, contrast, and color tones.
