If you download the installer, in the doc now there is a shooting consideration section
(will make a FAQ link at some point).Basically use the maximum FPS you can shoot at and the shortest exposure time possible (so there is less motion blur in the source, there is the noise issue at some point for night shots that might crawl in there). Also if possible avoid fisheye type lens… it’s hard for objects that come in and out the screen.
Sometimes you end up with option more resolution versus more frame rate. Then it’s content dependant, the more the content is fast action (like sports) go for more FPS over more resolution.
For the regular version, it’s basically the same thing in AE and Premiere (same plugin). If your machine has many CPU and you enable AE multi-processing you will get a bit faster renders in AE. For camera, stabilization (or tripod) is a good thing as it can look a bit weird to slowmo camera shakes.
Finally if you are shooting some acrobatic moment where the subject moves fast, try to do it over constant color background (low detail) or facing the action rather then sideways (if someone jumps left to right of image and on top you add camera motion, the tracker can have some issues as huge portion of the scene are suddently revealed in a frame that were hidden in previous one)…

Some camcorders have manual exposure settings (AE is automatic exposure).
In manual exposure mode set the shutter speed to the smallest possible time (the camera might display 200 for example to mean 1/200th of a second) that you can compensate the Aperture opening settings so the exposure level is decent.Pierre
