When I was working with video (U-matic, S-VHS and Digital Beta tape, CubiComp,
NuVista, Targa and other hardware, Picture Maker, Macromind3d, 3D-Studio,
Stratavision, Lightwave and other software), the kind of image Vamp mentioned was
the type of image we worked with.

I'll have to run POV through some checks to see exactly what it's doing... and
how it's output can be piped properly to broadcast. It could be as simple as
compositing frames from fields in post (which seems to be what Thorsten is
saying). IIRC, when I looked into this in 3.1, I said to myself something like
"oh, that's strange... hmmm.... Ah, I see. Still useful". Now I just have to
remember the details of all that.
