Every Video i render Has a thin Half pixel border
Windows 11 Running After effects 2023 & Premiere 2023 where both issues exist.
When I use a white solid or a shape layer as a background, I get a weird border artifact that appears only at certain times in the program, but always in the renders.
In the attached image “Boarder issue 2” and “Boarder issue 3” you can see the lines appearing at different viewport zoom levels (12.5% and 25%) they disappear at 50% and at 100%, but regardless of what the viewport is, they will appear in the final render.
If I add a white rectangle/solid behind the video like in “Boarder issue 4” the outline disappears (in this case I put the solid behind half of the video) but it will still appear in the render.
Trying to export from premiere leads to a similar result, in “border issue” you can see scaling down the video (or up to try and crop the border) still results in a new border being created.
I have rendered in H.264, MOV. Transparency videos. none successful.
Please if you have any idea of what I am doing wrong or if this is just a bug let me know. Affecting my client’s work.

My first guess is that your source imagery was created with dark edges somehow. Try masking the image so the edges are cropped a little and see what happens.

The Lines still appear even when just using a shape layer and a solid in a pre-comp, which is what the pink ball is one of the images I supplied

Have you tried exporting to prores 422hq or something with less compression, and then export that to h264?
-
yes,I’ve rendered in many different formats
-
Before you render, if you look at just the alpha channel in the comp viewer, are the lines present there ?
Perhaps your layers are 1 pixel smaller than your comps, and your composition background – if set to white – will not show you the “holes”. If you then render via Adobe Media Encoder (Just an assumption as your project is full of MP4s), AME forces a black background color.

this is not the case, I have expanded the background past the bounds of the comp to ensure there are no blank spots. it also wouldn’t explain the outlines of a comp inside another comp
-
Probably not the case, but you don’t have a layer style on the problematic layers, do you?
-
unfortunately no, the line can still appear with just a shape layer and a background layer both set to normal
