I gotta say, I’m not sure why you’re having trouble. I downloaded the file, ran the 3D camera tracker, and it solved a perfect track, first try–I didn’t even need to specify camera AOV or use Detailed Analysis. Pinned a solid to the grass round with no problem.
I’m assuming you’re going to roto the background and place the soccer player in an environment. Based on what I’m seeing, the camera track ought to be the easiest part–the roto is gonna be a pain, but the matchmoving is a simple job.

You want to do a 3D Camera track? What’s your goal?
-
Yeah, exactly–the Ray-Traced was the only option, and as we all know, it’s sloooooooow. I’m just happy to have something that works quickly.

If you reduce fps, you can reduce bitrate by a LOT. Bitrate and resolution determine your filesize–reducing the framerate just means that you can compress each frame less at super low bitrates. Maybe try going down to 0.1 mbps, see what happens.

At anything like HD resolution, your file sizes are about as small as they’re going to get without reducing the bitrate down to nothing. You’ve got an hour of video–regardless of how little it changes, there are still 30 frames per second’s worth of data being compressed in there.
I’m wondering if doing something truly ridiculous, like reducing the framerate down to something like 1 fps, would work for something like this. I’ve never tried it, but hey, there’s a first time for everything.

If it’s just using the audio from the wrong camera, right-click the MultiCam clip, and select “Open In Timeline.” Then either move the correct camera’s audio clip to the track with audio enabled, or enable the track where it is and mute the incorrect ones.

In a nutshell, yes. And let me be clear–I’m not bashing this camera. For certain fields, this is a great system. But for ultimate flexibility, it’s not what I’d choose.
Fixed lenses are often only so-so in terms of quality, speed, color rendering, etc, and if you need a different look, or a macro lens, or an ultrawide, you’re sort of stuck. Even in the hands of a smart cinematographer, you can only do so much with a given system–that’s why we have so many options available to us today ☺ The out-of-focus areas on a full frame sensor with a 50mm lens don’t look identical to a 1″ sensor on a 25mm lens, even though the FOV is theoretically the same. On a large sensor, I can deepen my DOF by stopping up, but there’s almost no chance I can get equivalent shallow DOF on a small sensor, even with a ridiculously fast lens.
I’m sure the files coming out of this camera would be perfectly good, and nice for color grading. Sometimes smaller sensors in all-in-one camcorder systems aren’t as good in lower-light situations, and can be noisy in any case, but I haven’t used a new one in awhile, so maybe it’s getting better. I used to use a Canon XA20 and Canon 5DIII side by side–same codec, pretty close in terms of when they were designed–but the 5D blew away the camcorder in terms of noise, performance in less-than-ideal light, and versatility.
My point is, though, there’s a lot of demand for a certain cinematic look these days that tends to come more easily with larger-sensor, interchangeable lens systems, and the demand for ENG-style all-in-one camcorders is more limited, mostly to ENG and corporate communications-style stuff. Everyone else wants the movie look, for better or for worse.
Now, if you’re in a situation where you need autofocus…that’s a whole different story. For that, I’d choose an ENG camera all day long, and would take a good hard look at the XF705.

I mean, just for simple VFX shots alone, it could be a game-changer. Get your greenscreen footage, do a 3D camera track, pull the key, drop it into an Orb instance with an environment map, and you’re in business. I’ve got to believe that it would be super useful for VFX previz-type scenarios, especially. Certainly for 3D motion graphics, it’ll be a fantastic tool.
