I agree with RafaMar about percentages vs pixels, it is more intuitive
for an user.
I spoke about in different place, for example:

I think it is not good that these sliders are linked to the values
seen below the timeline.
It is true that on the X and Y axes you can drag directly from the
monitor.
But the fact that the sliders are limited by the values of the
mentioned box below the timeline, can mislead users and make editing
difficult.
These sliders should be independent and work with percentages (%) and
not pixels. I mean, in numerical value, yes in pixels, but the slider
internally in%.

For example on a fullHD (1920x1080) slider X axis in the center, 0%
centered image, the slider at its right limit 100% shifts the 1920px
video frame to the right, and vice versa, -100% -1920px
And the same Zoom, in the center 0%, size 1 in the numerical box, if
we move to the left we reduce it to 0.01%, value 0.01 in the numerical
box, if we move to the right, we enlarge, by example up to a value of
1000% what would be zoom x10 or 10 in the numerical value.
