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. Hank wrote: 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. regards Dirk Taggesell
