It may be the same in the Kayak, but the 4:3 / 16:9 switch changes the "Geometry" of the [b]Kalypso[/b] World. In 4:3, there are 4 units from the left edge to the centre of the screen, and 3 units from the top to the centre. In 16:9, there are 16 units from the left edge to the centre of the screen, and 9 units from the top to the centre. The size of the units is therefore different. Moving an image (via a Transform Engine) 8 units to the left will move the picture totally off screen in 4:3, but as soon as you switch to 16:9, the image is exactly a quarter off screen. That's because 8 units is the entire screen width in 4:3, and a quarter of a screen width in 16:9. This is the reason why you can't take E-Mems from one world and just run them in the other without making some changes. Check parameters such as: Transform Engines (positions in X, Y and Z will be affected, as will Perspective and Z-Axis Rotation) Wipes (esp their position and softness, and if you have applied Aspect) Key Masks Many years ago we used an old analogue mixer (an Ampex Century, and therefore definitely 4:3) to produce widescreen analogue programs. We simply fed it with cameras that were set to 16:9, all our replays were 16:9, we switched our monitors to display 16:9. Our output program was for all intents and purposes a widescreen program. The only tell-tale sign that the switcher was really operating with 4:3 geometry was that our DPM-700 (also a 4:3 device) could not produce the correct geometry when we did a Z-Axis rotate: the image appeared to Skew as it spins. Other than that, no one would have known that we didn't have a brand new 16:9 vision switcher. TV's all make-believe, after all.

The 4x3 or 16x9 has to do with the DVE settings & wipe aspect settings - it's the monitors that determine the output. If you put your monitors into 16x9 mode, you'll get what you want. Switchers themselves do create a 4x3 or 16x9 image...only devices that create video do that (like CG's, VTR's, Servers, & Cameras). So it's the monitor settings that will show you a difference. Switchers just pass the video...there are the same number of pixels in a 4x3 as in a 16x9 SD image - they're just stretched by the creation device. So changing the aspect in the switcher will only change the aspect of you wipes & the X & Y numbers of the DVE.
