Don't pay too much attention to Karl, lostinqueens. He's running Linux, and he's not testing in the common Windows or OSX browsers or other media players, and that's where this failure is showing up.
The only thing I do is point and click. Everything works within jAlbum regarding displaying media. I love jAlbum.
Here's the solution to the problem, without having to use any external encoder or any preprocessing. Go to Album > Settings > Videos > Resolution, and choose anything other than Original video. Choosing 1080p (Full HD), for example, works in all browsers. The rotate works properly, and the video plays with all player scripts - Turtle uses jPlayer, Matrix uses JW Player, and Minimal uses a simple <video> tag.
Note that if this video were also an anamorphic, jAlbum would still be fooled about its dimensions, and the video frame would be in the wrong aspect ratio. That's a separate problem.
Were you running jAlbum 12.2.4 with Turtle 5.2.5 on a Windows 7 x64 machine?
No. However I am a physicist. Physicists are standing on the shoulders of giants. Thus they are seeing a little further than the average windows user. Specifically I need not instantiate Windows 7 on my machine to figure out what your problem is.
And I'll ask this question again: Do you think we're all idiots?
