My understanding of "perspective" must be limited because
the above paragraph makes no sense to me.

If you are referring to the aspect ratio of the thumbnails, there
are three different parts involved. There is the aspect ratio of the
"Frame", there is the aspect ratio of the "thumbnail" layer, and
there is the aspect ratio of the clip itself. In TDA itself all the
aspect ratios are maintained, when resizing.

This may sound confusing, but is provided to give you an idea
of how these factors can be manipulated, a short answer follows.
The "Frame" and "Thumbnail" layers can be made to any
dimensions, and thus aspect ratio. The clip or still image that is
displayed on the thumbnail layer however is restricted to 4:3 or
16:9 aspect ratios. This means that if you have a thumbnail layer
that is shorter and wider, the image/clip will be fit to the width
and only that portion of the image/clip that fits within the height
will be displayed. (From the center of the image/clip) In other
words, you would see everything from side to side but only a
slice of the image/clip from top to bottom. As if the top and
bottom had been cropped off.

The short answer is that only 4:3 and 16:9 are supported.

{ This is the main reason the "Thumbnail Speck" trick was
needed }
