Clipping by pixels in Premiere Pro 1.5

I'm having a problem with Premiere Pro 1.5 running under Win XP SP2.
Any help you can provide will be greatly appreciated.

I have some home video shot on DV and captured to AVI. I'm making a
credit sequence in which the right half of the screen is black with
titles overlayed and the left half displays video. I'm modifying dozens
of short clips and each one requires its own individual settings. I'll
use one clip as an example.

In Clip A, Cousin Bertha is in the center of the frame. I need her on
the left side, so I use the "Position" effect to move the video 220
pixels to the left. That leaves a big black rectangle on the right hand
side of the screen, measuring 220 pixels (wide) by 480 pixels (high).
And that's good; I *want* a black rectangle. That's where I'm going to
display my text. But I need that rectangle to be larger - 360 pixels
wide, to be exact - so I want to use the "Clip" effect to add another
140px.

Except that I can't; not directly, anyway. In the "Clip" settings, the
default is to measure everything in "percent." So you can make the
rectangle five percent of the width or 20 percent of the height or
whatever; anything up to 99 percent. There is an option that allows you
to change the measurements to pixels, but when you do, the counter will
still only go up to 99. The visual confirms that it's clipping pixels
instead of percents (if Clip > Right is set to 99, there's an extra 99
pixels of black space visible on the video) so it *can* clip by pixels.
It just can't do more than 99 of them. I need to clip 140 pixels, so
I'm SOL.

Now, since I know the dimensions of the video, I can, theoretically,
translate from percent to pixels. I set up some tables in Excel to help
me (1% = 7.2px, 5% = 36px, etc.) and, using them, I can get pretty
close, but I can't get it exactly right. Plus the numbers quickly get
confusing. It's slow going and I need to do this with dozens of clips,
all of which need to match up. With the percent conversion method, they
never quite do. And god forbid I should have to go back and make any
editorial changes. Then I might have to re-jigger everything.


I considered doing the clipping in another program and then importing
the clips back into Premiere. I'm concerned that I'll have to reencode
and this could make things even more complicated than they already are.
If someone more knowledgable than myself can offer some words of
reassurance on this option, I'll certainly re-consider it.

I considered moving the whole project to another big league video
editor such as Vegas. The problem: it took me forever to get comfy with
Premiere. I don't really have the stamina or time to learn a whole new
program.

I tried setting the measurement to pixels, closing Premiere, then
re-opening it. The setting stayed where I left it, but the problem
persisted.

I tried upgrading to Premiere Pro 2.0, thinking maybe Adobe has fixed
the bug. But for the new version, Adobe tells me, I'm going to need a
processor that supports "the SSE2 instruction set." For me, this means
upgrading the processor and the MB. Not an option at the moment,
unfortunately.

I suppose I could use Avisynth; set the clipping, import the Avisynth
file. This still seems like a long way around.

I've googled the problem and come up with snake eyes. Any suggestions,
ideas, thoughts, or methods of committing suicide painlessly?

Clay,
It sounds to me like you're making this a lot more difficult than it
has to be. Why don't you use the titling tool to create a black box
precisely the size you want on the right hand side. Then position it
on the video track above each video clip, and use clip effects to
resize each piece of video so that it fills the left side nicely.
