Stabilize media - General footage vs. handheld

Hey guys,
So, I've been messing around with the new stabilize media feature and couldn't find very good documentation on it. Has anyone figured out the differences between General Footage and Handheld Camera? And what about the slow vs. fast, fast vs. medium settings?

Have a look here
Mercalli manual

I was about to post the same exact question -- in MS10, what exactly do the settings in this dialog mean, so we can make smart choices about which to use when.

I flipped through the Mercalli document you referenced-- but it doesn't seem to answer the question. it has modes like "Handycam: smooth watched scenery", and a list of like 30.

MS10 has only 6 choices, and they aren't understandable. (when should you pick "general footage" versus "handheld camera"? I presume if it's really bumpy, you pick "handheld"..) But that still leaves questions:
- does "handheld camera, very smooth" mean MORE INTENSE correction than "fast-moving scene" or does it mean the scene started out smooth?
- Should I always pick the 3rd in either category because it will be "best" if I'm willing to wait for rendering?
- what does "rolling shutter correction" mean and when should I check it? (again, always if I 'want the best' and am willing to wait?

THanks for any additional help/info/tips!

The settings you mention are just templates. You can adjust the settings beyond those. Take your best guess and check it out. No harm in trying!

- The third option is the best in terms of quality. It will perform the most tedious calculations to get the best (according to the software) stabilized media render, VMS offers the general footage (fast, medium or slow/intensive analysis) or handheld options (slow moving, fast moving, very smooth).

General footage is likely tripod based. Then, you just need to pick the type of scene you ecorded. Handheld is for handheld video, but I'm not sure of the answer to Question 2.

No harm picking the best/most intense option if you don't mind waiting.

Rolling shutter appears in CMOS cameras. If the footage is static, there is no issue. If you pan or if there is action, due to the way the camera records the each line in the fame, if something moves quickly in the scene, then it could appear blurred in the video because not all parts of the image are recorded at the same time. See here for more complete details http://en.wikipedia.org/wiki/Rolling_shutter. If you have a CCD camcorder, you don't have to worry about this.

I've been working on this a lot recently due to footage shot on a small camcorder with poor stabilisation. I've found the best method, in my opinion, is to use Handheld camera - fast, for clips that are not too shaky and Handheld camera - slow for clips that have fairly violent shakes (as in telephoto shots). It doesn't seem to make any difference if the scene is fast moving or slow moving. I know that there's a limit. If you try to stabilise a clip that's too shaky it starts shimmering and blurring.
