Most clips are filmed from the three-quarter angle. Alternate viewing angles are sometimes provided with the demonstrators performing in different orientations, or in a separate clip altogether. In most cases the demonstrators' arms are not in frame to allow an unobstructed view of the lower body.

The clips are provided in Real Media format (.RM) and the Audio Video Interleave format (.AVI):

RM files are small and can be streamed i.e. if you have a fast enough machine and connection, it may not be necessary to download the files.

AVI files are larger and should be downloaded by Right clicking on the link, selecting "Save Target As...", and following the prompts. Their advantage is that they perform better on older machines and can be set to play continuously (by right–clicking the picture as it plays, selecting «Options», «Playback», «Repeat Forever»). The AVI files have a much higher image and sound quality.
