Premiere not rendering background video on export

I’m on a MBP M2 Max using the latest version of PrP 26.5.2

A number of times now I have exported my sequence using AME and the background video of a graphic/still has not rendered on export. Usually these backgrounds are duplicates of stills that are scaled up with a gaussian blur effect applied in order to provide background for a vertical picture or graphic (see attached pict). This was not happening in previous versions of Premiere.

@einsof613 I found a pre-existing ticket for this and the fix is already in the current Beta, so the next release should resolve this. I found that if your Program Monitor is set to Full and you choose “Match Source” so that there is no scaling on the initial export, then the backgrounds will export properly our of AME. This does mean you may need to make an initial Export of your sequence and then you can run that export through AME again to the desired preset.

Thank you for your post and let me know if you have any additional questions.

Amy, thank you for your attention to this and all your help. I’m hoping to see the fix in the new update.
Just to let you know, I always have my Program set to full and also always select Match Source when exporting with AME, but was still seeing the issue. I started using your suggestion of an adjustment layer with the gaussian effect applied there and it has been working well.
Thanks again for all you help!

Hello @einsof613

Files are received and I was able to reproduce this issue. I did notice that if I rendered the backgrounds by selecting those tracks and using Sequence → Render Selection, they would export properly. This may be best practice as a workaround while we work on this.

Thank you,

Amy

Thank you for the suggestion.
The main issue is that I don’t think ME utilizes preview/render files when it exports, so I would only be able to directly export out of Premiere. Unless I’m wrong about that, but there is a pop-up within the software that says this.

@Amy the Stuv Here’s another example where the video looks fine in my timeline, but when I go over to my export window you can see that the background channel is not there.

@einsof613 Thank you for the additional information. I’m wondering if you could try a direct export from Premiere and let me know if those same backgrounds do not render directly out of Premiere? If that export is correct, this could indicate the issue is in the dynamic link to AME and then we can troubleshoot that connection. If not, then the issue is overall encoding in both Premiere and AME and we can look into that.

A screenshot of the layers on your timeline could help too so that we can try recreating a timeline with stock images on our end. I have not been able to recreate this issue yet, unfortunately. Thank you for testing on your end!

Thanks for your reply. Exporting both directly from PrP and AME gave the same results.
I now have to go through my entire timeline to double-check each effect. Tedious after a long edit. It seems that the main issue is with the Gaussian Blur effect. The only thing that seems to fix it is to nest the bottom/background layer and then apply the effect to the nest.
But, this should not have to be the case and is extra work on my end, especially when i need to do this 20-30 times in each timeline.

Hello @einsof613

Welcome back to the Premiere Forums. Thank you for your bug report. I’m having a little trouble reproducing this issue on my end and could use some clarity on the steps to reproduce.

A screenshot of your timeline with the layers and your Effects Control Panel or Properties Panel showing the layered effects would be helpful. When you say “Duplicates of Stills” is this a freeze frame from a video or a standard 1920x1080 image zoomed in about how much? When it plays in the timeline do you see this background? Does the background render when exporting directly out of Premiere or only when run through AME?

Hoping to help,

Amy

Hi Amy,

Thanks so much for getting back to me.
I will post some screenshots so you have a better idea what I’m talking about. Everything looks and plays fine on my timeline but on export with AME the background is missing. This has happened a few times now after upgrading. When I park on this effect in AME I can see that the background is messed up, but I cannot be expected to check every layered graphic each time I need to export. I did not export directly from Premiere.

This is how the effect should look:
