Premiere is imprinting artifacting on my after effects render. I’ve reported this issue several times. I render something out of After Effects. bring it into adobe premiere. looks fine in the source monitor of premiere. then you lay it down on the timeline and it has all these weird artifacts on it. look at what i circled in the attached screenshot. I drag that same MOV render back into after effects and the artifacting isnt there. I cleared my cache in AE and premiere. that didnt fix it. re rendered the gfx from scratch. same result. I’m using Premiere 2025 (version 25.6.6 Buil 5) and After Effects 2025 (Version 25.6.6 build 4). Do not ask me to try to use a later version of these programs. The company I work for has asked that I use 2025 because they have not upgraded to 2026 and cant open those projects.

Yes sequence settings are 1920x1080. I can do a screen share, but it needs to be sent to you over private message and not posted here on this public forum. I am on Mac Tahoe 26.5.1 but i’m almost certain it’s not related to the OS because I’ve reported this issue a few times under different mac operating versions. I’ll go DM you for a dropbox upload link

@rachelcenter Thank you so much for taking the time to gather those files, and that super helpful and thorough screen recording. I’ve passed these bug report details along to our team, and I’ll provide an update once I receive it.

It sounds like at least there’s a workaround for now with fresh export or straight test that may assist while these finicky “jaggies” are better examined. Very sorry for these frustrations happening like that.

Thank you once again!

a few other times that I’ve experienced this bug, you would have to render from scratch with a new name and bring it into premiere but the minute you closed out of premiere and came back in those brand new renders had artifacting all over again.

“use alpha premultiplication from file”, i dont believe this to be the issue because i dont have issues with any of my other graphics that have an alpha channel embedded
i started a new sequence in this project and put a yelllow solid down and then put the new render (lossless straight alpha test.mov) on top of it, and i dont see the issue on the straight alpha test. but listen to this. then i take the file in question, from a day or so ago, and put it into the source monitor and cut it onto the same timeline with the yellow solid, and its not displaying the issue at all. so then i go to the other timeline where the issue is present. and i click copy, then come to the new sequence and hit paste, and paste that graphic over the yellow solid and the artifacting is still there. and i go to effects controls and theres no effects applied to it. does this point towards the problem being with the sequence? (cant be if a copy paste onto a new sequence replicated the issue)
attached is the settings i always use (Without issue) to render out of after effects

@rachelcenter Appreciate your time trying those out! Yes, that is quite curious it’s retained artifacting in the copy/paste. I see the render is at 1920x1080, is your sequence in Premiere also matching that?

1) Could you send a short screen recording showing that exact behavior:

the file looking clean when brought in fresh
the older timeline clip showing the artifact
and the artifact returning when that older clip is copied/pasted

2) Can you confirm if on Windows or Mac and what driver version/build or which macOS?

Since the same file looks clean when brought in fresh, but the artifact comes back when the older timeline clip is copied/pasted, this feels more like something Premiere is carrying with that clip instance rather than a problem with the render file itself.

Would you be able to share even a simplified Premiere project with just the clip in question and the sequence where the artifact appears for our team to further investigate? I can provide a Dropbox upload link, or you can DM me a link to a location you prefer, such as Google Drive.

Thanks again, the extra testing you did was very useful and your time’s appreciated.

Hi @rachelcenter

Welcome back to the Premiere forums. Thanks for explaining about your issue and including that helpful screenshot. Sorry for any frustrations going on with those artifacts! Since the file looks okay in After Effects and in Premiere’s Source monitor, but shows the artifacts once it is placed on the timeline, this could be an issue with alpha/compositing.

To help us troubleshoot, are you on a Mac (and which macOS) or Windows (Win11 and what driver version/build)?

A few things to try:

In Premiere, right click the rendered file in the Project panel and choose Modify > Interpret Footage. Check the Alpha Channel setting there.
If possible, render a short test out of After Effects using Straight Alpha instead of Premultiplied Alpha.
You can place it over a solid black background and then a solid white background, and let us know if the edge changes.

To further narrow things down, let us know the exact settings you exported from After Effects, can just screenshot the media file properties and what export settings were used.

Hope to help!
Katie
