Prime Image makes a box called the PassPort 4000 which provides the Video
Toaster and, therefore, the Flyer with PAL input and output. This has opened up
the PAL market for Newtek.
But what about the Quality? AFAIK the toaster can only work in NTSC which
forces these box to convert PAL to NTSC and vice versa. This will result in no
more smooth camera turns (slides) because of the Interpolation from 50 frames
per secont to 60 and back to 50. And a decent loss of picture quality because
of the interpolation from ca.576 PAL-lines to the ca.480 NTSC-scanlines and
ofcause the conversion from NTSC to PAL at the toaster output. I cannot imagine
this to be
satisfying in quality.

As to transitions on the Flyer, you can create ANY transition desired using the
Toaster's LightWave 3D and render the resulting images to a clip on the Flyer
harddrives. Of course, you have all the realtime transitions of the Toaster, as
before, as you mentioned. However, LightWave can let you create any desired
transition clip you wish with multiple sources combined for the final clip.
Using Hollywood F/X and WaveMaker, many sequences can be created with simple
GUI interfaces that don't require extensive knowledge of LW either.
I am a big LW fan and I love it (standalone 3.5), but one question comes to
mind:
If You apply a planar image map with an image sequence to a rectangle, how do
You achieve exact the same luminance and saturation like that of the "normal"
video which comes before the LW-generated 3D-Effect?
(Explanation: a scene should be fly out of the screen with the next scene lying
in the background. From the beginning to the end of the effect these two scenes
have to be rendered.) Don't You see a difference (luma/sat..) between the last
pictures of the "real" video and the rendered effect?
And what happens to the fields of the original video? AFAIK LW doesn't use
fields in image maps.
