Question

aerendercore keeps rising and rising

Hi. Im using Adobe Premiere with AE-Compositions inside the Projects. Now it turns out that those projects keep sucking power, and finally i cant open anything else while rendering a project in premiere, even the finder.
Any solution for that (sorry if reposting)?

Hey Andreas,

As a workaround, you can select all After Effects compositions in your Premiere Pro Sequence, Right-click, and select Render and Replace. I recommend doing this for the compositions that don't require further changes in After Effects.

 

Thanks,

Ishan

Try using Render and Replace:

Hi Andreas23715480stfn,

 

We're sorry about the poor experience. We're investigating a similar issue in the latest version, where rendering or exporting might increase memory usage. Can you please confirm if you are using the latest version of Premiere Pro (v25.4) & if you are noticing any spike in memory utilization in Task Manager/Activity Monitor?

 

Thanks,

Sumeet

Hi Sumeet,

yes, im using the latest versions.
Everything is fine, but when im using AE-Compositions in Premiere Projects, the aerendercore starts to get crazy in the Activity Monitor. After 1 Minute, i cant open any other software anymore. After 2 minutes, everything crashes down.

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
