Other Stuff



We, and the videocam, are going to traverse across the width of the subject, so we can easily generate as much width as we want, just by traversing as far as necessary. But we also need to cover the subject's height. Since a videocam's image is wider (or in the case of HD, much wider) than it is high, we rotate the camera through 90° (in what would be called 'portrait mode' in a still camera, and yes, this is unusual for video). Then we set the zoom to cover the subject's height (while rotated), and the exposure to 'manual' (we don't want Automatic Exposure changing things during the shoot - trust me).
Incidentally, rotating the camera also simplifies the processing stage, as TravoMaker needs to extract only a few complete lines from each video frame, rather than a few pixels from every line otherwise.

Another consideration is avoiding (or minimising) camera shake. A tripod won't help us here, because we'll be moving. A good solution is a bracket which clamps on a car window which is wound down to leave about two inches showing. Then you need to mount your videocam on that, but rotated 90° (left, preferably). This may require another bracket/gizmo.

We don't want any other vehicles to pass between ours and the subject, so perhaps early morning works for where you are shooting. Start shooting, and drive along a line approximately parallel to the main shape of your subject, or along Main Street. Stop shooting when you've gone far enough (yes, that's obvious, but sometimes other consideration make me forget).


If you're shooting AVCHD video, you will need to convert that (specifically, the *.MTS file, which is found deep within AVCHD's 'PRIVATE' folder hierarchy), to an *.mpg file, which TravoMaker can handle. Currently, Nero Vision (and possibly other software) can do this.
N.B. This limitation will be removed in an updated version of TravoMaker when some other software, which TravoMaker links to, gains AVCHD capability.

A note re potential for confusion: When dealing with a video frame, we think of the shorter dimension being the frame height, and the longer dimension being the width. But we rotated the camera while shooting, and when taking frames apart to create Travo images, we turn the image strips back to the expected orientation. It's easy to get width and height mixed up.
