Well, I thought the same thing. So I tried a completely different shot
- talking head, nice and sharp, no filters, etc. The result is better,
but I still see the problem.
Now, though, I've noticed something else. If NO effect is applied to
the HD clip, when brought into an SD sequence, the shot (which has an
apparent blow-up, since this is an SD cut of an HD shot) looks nice and
sharp.
But, if ANY effect is applied, which causes a YUV-RGB conversion, like a
DVE or a simple Color Correct, the picture immediately goes soft, even
if no parameter changes are made. If an effect which does not require a
conversion, like a Graphics effect, is applied, no softness occurs.
Hmmm... interesting. Any thoughts on what the heck is going on here?
I think we're getting close!

Hi Ed -
Just tried basically the same thing, and the only time I got any
softness
was when the HD shot was slightly out of focus. On an HD monitor it
looked
fine, the SD downconvert looked great, but the "close-up" of the HD on
an SD
timeline looked soft. Could this be the problem?
