Hey everyone,
I have a bit of a problem while using a luma matte on a video. I’m using a custom video to transition between photos, the idea is that a circle grows showing the next image:
In this render however the circle is oval, while in the studio it shows correctly. It’s as if it somehow gets stretched during the render.
This is the asset:
Does anyone have any idea why this is happening and how to resolve this issue?
Thanks! 
Hey @Ondev, it looks like the issue might be with the luma transition you’ve chosen. You were aiming for a circular transition but ended up with an oval shape instead, correct? I tested the luma matte you shared and also observed an oval transition in the output video.
However, when I switched to a different luma transition, I managed to achieve the circular effect you were looking for, with the circle smoothly expanding to reveal the next image.
Thanks for the quick reply, this is indeed the problem I was experiencing. Gonna give this a try! Thanks
The issue seems to be caused by the fact that I’m using a video in portrait orientation.
Alright. Are you seeing the circular transition effect now?
