List of aspect ratios (used in The Wiggles)

Full Screen
The Wiggles used full screen in the early videos (1991-2004). If a full screen sequence was used in a wide screen video or episode, it would need borders.

Letterbox
Letterbox (different than Widescreen) was only used in some editions of "Cold Spaghetti Western".

Widescreen
The Wiggles started using Widescreen in the more recent videos (2004-present).
