Other interesting thing was that a US poster said it looked terrible
in the US too, which sort of rules out the NTSC to PAL conversion
has being the main culprit.

Dallas was tape-edited.

Thing is film has been transferred to tape since pretty well the
earliest days of tape. Think film inserts on just about every type
of studio based production. So why all of a sudden were the results
so poor? --

At this point, I move into conjecture, but...

Flying spot scanners were the exception, not the rule in US
television. Far more common was a basic projector with a 5-bladed
shutter shooting through a mirror multiplexer into a vidicon camera.
Results were adequate but never stunning. Add to this some
generation loss during the process of editing analogue C-format tape
(and then standards conversion for export) and it's amazing we could
see pictures.

Seriously? I didn't realise that point-a-camera-at-a-projector was ever used
professionally - I thought it was confined to the amateur market: those
mirror/prism arrangements that camera shops used to sell for transferring
your Super 8 onto video and which never gave even lighting across the whole
frame. I'd assumed that flying-spot (and later single-row CCD) telecines
were universal throughout the TV industry since God was a lad.

So American telecines used intermittent motion and rotating shutters? Is
that because of the infamous 3:2 pulldown? Was there enough time for the
shutter to move and the frame to advance between one field and another
between one three-field film frame and the next? Do modern US telecines
still require anything different mechanically or do they just use single-row
CCDs and then a slightly more complex playout from frame store than simple
odd+even field? Does made-for-TV film in the US used non-standard 30 fps
film (like we use non-standard 25 fps) or do they still shoot at 24 fps and
use 3:2 pulldown?
