premiere altering my AE renders to include odd artifcating in the background

[rachelcenter]

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 @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

@IanB_360I'll message you a private dropbox link

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

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

[IanB_360]

@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.

but i thought i didnt have any colored background. or any background for that matter. its an alpha channel background

[rachelcenter]

it's happening again! is there a fix for this?

[rachelcenter]

@IanB_360this time I'm using this template called the Lookbook, and i rendered out several scens and only one of them is giving me this graphic issue. https://elements.envato.com/the-lookbook-JWYUVLZ

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.

[gregsgammato]

The MOV file is also available here for reproduction: https://www.dropbox.com/scl/fi/pr9bytk86puxmo4sqd6c7/Awards_CC_Titles-OldManRhythm.mov?rlkey=her7sxv...

[gregsgammato]

Thanks, @jamieclarke - got it. Maybe this topic would be better for the AE boards, then. You're saying if I had a video that was mostly blue and I decided to use a black comp background, then this same image would show up - only black? I feel like that would still be troubling for me. I'll get back to work - thanks!

[gregsgammato]

Even more confusingly, regarding consistency, this is an in-context screenshot from an export I did last week. No issues with this one. (Exported from Pr25)

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.

Try changing the Interpret footage Alpha Channel setting.

It origin is Ae save the image to a different alpha setting.

[R Neil Haugen]

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.

Hi @Gramafilm352744625nxe 

Yes this my be similar to another issue I have seen. I am merging you into that post. If this is a different issue than what I merge you into please let me know.

Ian

[rachelcenter]

this may not fix it altogether but when you do Command K to bring up composition settings, see where it says "background color"? make sure thats not blue.

[Kirsten22]

My renders from After Effects that I import into Premiere Pro look great at first, then whenever I close and reopen Premiere Pro they get this strange blue effect that also shows up when I export media.

My export settings are formated for Quicktime, and Channel output is RGB + Alpha for transparency.

I've added a screenshot as well.

This only happened with the last few versions of Premiere Pro. I didn't change the way I exported renders from AE, and didn't have this issue previously. The only way I've found to fix it, is either start from scratch by importing the renders again, or downloading an older version of Premiere Pro (which doesn't always work and I can't always get it to open my project).

Am I doing something wrong or is this a new bug?

[IanB_360]

Hi @Kirsten22 

This is a known issue and I am merging this post to the current bug report. Right now the best workaround is to make sure the background is set to black before you export the graphics. 

Thank you

It happens so many years that the MOV with alpha file shows a weird green silhouette when imported into Premiere sometimes. It appears randomly. How to fix this?

[LW0121]

I export those mov files from After Effects. For some reason, video producers import them to the Premiere may have this issue sometimes.

[R Neil Haugen]

Try deslecting "composite in linear color" as that affects the image differently depending on whether the alpha channel is pre-mulitiplied or not.

[IanB_360]

Hi @LW0121 

I would take a look at what Neil has suggested and if that doesn't work see if your back plate is on a black background and then re export it. I am merging this with another issue that sounds similar but please let me know if this is a different issue. We have logged the Alpha channels not working properly as a bug with the team. 

Thank you

Ian
