Hmmmmmmm

Hmmmmmmm....... OK, one problem may be if you are doing multiple

levels of motion (rendering, exporting, importing the resultant file,

then applying motion again...), since each motion use without the

optimum values used (any horizontal motion is OK, but in vertical

direction, my notes show values of .5, 3.5, 6.5, etc. are best for

eliminating the *slight* softening that can result from using the

motion tool without resizing - but if the image is in motion, there

are no possible optimum values). Another problem may be more important

I found a bug in P-6 compared with P-5 in that when a colored edge

was used in a wipe or iris transition, the image softened a LOT.

The cure was to specify "square pixels" in the P-6 set-up (resulting

in 720x480-proportion preview window instead of 43) - the transitions

then worked properly in P-6. The project done in P-6 (I'm conservative,

and did not try it again until recently, though I've owned P-6

since it came out - but why "rock the boat" when P-5 worked so well

for me...? ;-) did not require the use of the motion-tool, so I

do not know if the use of square pixels will solve the problem - but

I suspect it might... You would need to redo all operations,

unfortunately - but a test is worth a try on a new experimental

project...

Thanks once again for your help and input here. This must be almost as

trying for you as it is for me.

So far I've been doing my repositioning (and as per your instructions NOT

RESIZING etc.). But I am still having problems

For one thing, I have about eight corrections in the first take alone.

This is a 2.5 minute shot with tracking and dollying, and it has to be

corrected all over the place.

As per my previous e-mail, losing sharpness is a big problem. Each

"correction is done in the motion menu and is between +4 and -4 in the

vertical. This is because the measurements used in the menu are not true,

but SCALE implementations -- in other words 4 pixels in MOTION MENU is

about 32 on the real image. Anyway, this is my problem. -(

However, could you explain what it is exactly I'm trying to avoid when I

make my corrections. I tried the process you suggested, but the Premiere

interface makes it clumsy and inaccurate. As I understand it I am trying

to avoid "interlacing problems" that will occur as I move my image up and

down -- fields moving out of alignment?

Is there a more precise way of calculating this so I can type in some

accurate numbers (i.e. use values that will not create softening in the

image). It seems there must be some kind of formula determining this. If

you could explain this concept a little more clearly, maybe I can figure

it out.

Again, sincere thanks.
