Media Encoder messes up the framing of my shots when rendering

Hi there,

Here's what I'm doing: 

I have a 4k video of someone talking to camera, so to add variation, I zoom in and out to different fixed positions. (I.e. scale to 100%, to 120% and 140%).

To make things easier for me, I set up different adjustment layers with a transform effect on them (on source) and scale to taste so I can then drop them on the timeline whenever I need to. I name them accordingly, "camera 1", "camera 2", etc...

When I render via Premiere, things look all right:

But when I render using Media Encoder, the issue appears:

Media Encoder seems to be scaling from the upper corner of the videos instead of from the center of the videos...

So I don't know if it's a bug nor what might be causing the issue.

Do any of you have an idea why this might be happening?

I'm using Windows 10, the version of Me is 25.1 (Build 65) and Pr is 25.1.0 (Build 73)

Best,

Mauro.
