You’d be amazed at how quickly natural light can shift–when you’re shooting outdoors, the sun goes behind a tree or cloud, and boom, two full stops of exposure change. Since it’s not your only source, it doesn’t have that much effect, but enough to be noticeable–I’d wager a beer that’s what’s going on.

I believe you can right-click on your captions in the bin, select Modify -> Interpret Footage, and changing the size of the subtitles there. Your captions may need to be set to Open Captions vs Closed Captions for this to work, I don’t recall off the top of my head.

[Mike Smith] “You don’t mention whether you are using progressive scan or interlaced video (at 24fps). Interlaced will allow you to push your pan a little faster before this kind of effect shows up – though it may have other effects which are unwelome for you.”
There’s no such thing as interlaced 23.976 fps video. But otherwise, Mike is completely correct: given the frame rate, you’re running into issues with the pan speed. Pan slower for smoother movement, pan faster for more motion blur. You could lower your shutter speed for more pleasing motion blur at the same speed, I suppose. Increasing shutter speed would make this look even worse.
One thing I notice is that there appears to be some kind of image stabilization going on in-camera that looks REALLY bad. In fact, it may be contributing to the problem–as it tries to stabilize and “catch up” to the movement, it may be introducing more judder. Put this camera on a tripod and turn the IS off; it may help.
If you’re not required to deliver 23.976, you could consider using a faster project framerate of 29.97, or even 59.94.

Did you check and make sure Auto ISO and Auto White Balance are both disabled? Also, it appears that you have some natural light leaking in the background at least; could the sun be moving in and out of clouds? That would cause small but noticeable exposure changes.

Good luck finding SSDs with any rpms at all, let alone 7200rpm!

I will have to give this a try–matching those two cameras drives me nuts. Thanks for sharing!

I mean, don’t get me wrong, I’m not shooting film. I don’t have budget for that.
Film is one of those things that, for me, might not be super useful because of the expense. But again: the benefits are intangible, and it seems like Mark is partially answering his own question when he opens by pointing out that the professionals at the absolute top end of our profession still choose to use film. They’re not doing that because it’s easier, because as we all know, it ain’t!
Frankly, it’s not really relevant whether IMAX films use other sources–many of those docs are limited by available footage. The point is that the IMAX medium is different, and measurably better, than any current digital option. Will that change someday? Probably. But for the same reason plenty of art photographers still use medium and large format film and develop manually using chemicals, I believe that it would be a mistake to abandon celluloid entirely.

Premiere Rush is the iMovie of the Adobe CC. It’s for people who don’t know how to edit and don’t want to take the time to learn a real NLE.

You might try doing a 3D Camera Track on the footage, inserting a slightly oversized solid into the 3D scene to match the ground plane, and then drawing the mask on the solid to refine the borders. Since the trees are moving on a different plane than the ground, Mocha might be having trouble resolving the motion of the tracked area.

[mark thompson] “Do people agree it is a waste of time or is there benefit from film that can make it through the process to delivery?”
…obviously SOMEBODY thinks there’s a benefit to it, or it wouldn’t still be in use. As long as you have the budget, it adds that “je ne sais quois” to the look.
Most of the benefits are not entirely quantifiable. The ones that ARE quantifiable: film records great detail and dynamic range, and can be rescanned years later to make new digital copies. It’s a great long-term storage medium. 70mm IMAX film is still the highest-resolution capture format available, by a long shot. Just ask Christopher Nolan about it!
Other unquantifiable benefits; unique color processes, grain structures, processing tricks, and things that are theoretically possible to replicate on digital, but in practice, just “feel” better.
