this is the 3rd time I've seen this issue in maybe a 2-3 year span (meaning each time issue resurfaces its a different mac os and different version of AE and premiere). if you look at the first picture thats what it looks like in AFter Effects. I rendered it out of after effects and brought it into premiere and it looked fine. and I'm on premiere 2025. Then I updated premiere today to 2025.1.0 and when I reopened premiere it had all this nasty blue outlines behind the text in my MOV. the last 2 times I had this happen, I re-rendered the text and it looked fine and then the minute you close out of the proejct and come back in, the issue is back. and can only be solved by re rendering a brand new MOV file and not closing out of premiere.

Hi, I've been having this issue for a few weeks now (since 2025 update) where when I add my alpha mov gfx on my premiere timeline, graphics appear with a blue or red outline. I've tried to change settings, delete media cache but nothing worked...

I was wondring if anyone have had this issue before and knew how to fix it ?

Thank you.

Ann had probably the best suggestion. I wouldjust add that anytime there's an alpha channel issue in Premiere, go into the Timeline panel's settings and de-select "composite in linear color". That sometimes sorts certain types of alpha issues.

Everyone's mileage always varies ...

Problem: I get the dreaded blue (or coloured) outline on my alphas once imported into Premiere.

It's been happening intermittently across different projects and different Macs & Adobe versions since 2020. Have looked in the forums over the years and there doesn't seem to be a line of best fit. Or definite solve.

The current solution: re-render the alphas in Ae — which I have to do pretty much every time I re-open the project in Premiere.

Troubleshooting:

Latest software updates
Played around with different interpret footage settings
Played with different codecs (Animation/Pr422HQ/Pr4444)
Ae alpha render settings (attached). Tried Premultiplied/Straight. Both work, then don't work upon re-opening projects in Pr.
Tried clearing cache / safe mode
Ae Alphas export fine and I can use them in other NLE's (Resolve) but when imported into Premiere, alphas intermittently have the blue outline.

Is this an actual bug in Ae/Pr or an Ae render settings issue?

My System:
Apple MBP M1 Pro 2021

macOS 15.3.1

However, I've been able to replicate the error on multiple Macs in our studio with different macOS versions and different Adobe Versions over the years.

Hi Jonagrey,

Thanks for creating the detailed post. This issue has been reported as a bug in Premiere Pro. I'll merge your post with the original thread.

Thanks,

Hello,

I have a sequence of 52 animated chyrons, created in After Effects 25.1. They all exported successfully as Quicktime RGB+Alpha, no audio MOV files. I did this for ease of use and transfer, rather than a PNG sequence.

When I imported the MOV files to my Premiere 24, there was no issue. However, when I upgraded to Premiere 25 (mid-project, oops), rather than being a transparent black and white image, a Cyan hue is present, even showing an outlilne before the graphic fades in - as seen in the videos below.

I'm attaching images of my sequence settings and a screenshot of my After Effects composition.

Is it as simple as the non-visible background color in AE being blue? Would having a non-visible black background color fix this issue?

Hi @gregsgammato - Thanks for submitting your bug report.

I believe you have answered your own question if you are using transparency then your comp background should be straight black.

@rachelcenter I deleted that response because It does not work. You can change the premultiplied over to straight but it still shows you the blue halo just less opacity. For now while Adobe looks into the issue I think the best bet is to change the background of the comp from Blue to Black. It may only be on comps with drop but we are currently attempting to figure it out. I did report your issue and I get the exact same results as you did.

Thank you for submitting the bug, we hope to have it fixed soon.

i have an email from adobe that says you responded to this thread with "I have attached some screen grabs for the modify clip panel. Let me know if this works as a workaround for you." but when I go to the thread i dont see any attachments

Hi @rachelcenter ,

I did manage to see the issue using the GFX you exported out. The first time I dropped it into Premiere Pro 25.1 it looked fine then the next time I opened the project it had the blue halos around the drop shadow area and I could not get it to work even after deleting the clip and dropping it back in. I am not entirely sure if this is the drop shadow and blue background that is causing this in After Effects or something in Premiere but I do see the issue. Can you send a screen shot of the export settings in After effects? And for a workaround I would just change the blue color for the comp background to black before you export and that should help. I will see what the team thinks and get this logged.

Thank you

Ian

Hi @rachelcenter ,

COuld you send me the file you exported that looked fine before the update? That way we can check it? And would you mind sending a screenshot of the export settings in After Effects?

Thank you

Ian
