AE 2025 FILE TO AE 2024

[Mike Sevigny]

In After Effects 2025, you can “Save as..” and select “Save a Copy as 24.x”

[Graham Quince]

To save as an AE24 version, go to File… Save As… Save a Copy As 24.x …

Adobe support two previous versions, so you can also go back to v23.

I’ve not tried, (but keep meaning to) to use Save as Copy as XML. This in theory should allow you to pass projects to much older versions.
