Unfortunately, currently it's not possible. All MVC decoders must decode all frames, starting at the first frame, and therefore they are currently unable to seek to a certain point in the movie to begin the decoding at that point. (In fact, there is a way to drop the beginning of the movie and start to encode only after a certain frame number, but it will be necessary to decode the beginning of the movie anyway, and that's long and useless.) That means that there is no practical way to encode only a specific chapter, or to provide the starting and ending frame numbers.
However, if you really want to do a short test, you can manually change the number of frames to encode in the __ENCODE_3D.cmd file. (You have to change that number two times, or 4 times if you encode in 2-pass mode.) That way, you can restrict the encoding to the beginning of the movie, and that should be sufficient to do a quick test. But it is impossible to encode the middle or end of the movie only, and therefore I will not implement that feature in the GUI. Sorry.
Note also that if you want to build a short MK3D after having computed the full movie, you can use the Mkvtoolnix GUI to cut a short sample anywhere in the movie. That may be handy if you need to provide a sample, but you'll have to encode the full movie anyway.
