MXF Import broken on AE 24.4.1

Question

Hey there!I've recently discovered that MXF files, which were rendered from AE with Media Encoder on previous versions seem to be broken on the latest AE version. Downgrading to 24.0.3 (as per an old unresolved post here on the community forums) fixes this issue and the file imports flawlessly, display alpha and also render correctly in new projects on this version.The original file was rendered using the Apple ProRes MXF format with the Apple ProRes 4444 with alpha preset in ME. I can provide the .mxf file if necessary but any and all previously rendered files do not import correctly in the current build. Steps to reproduce:- Create a comp on 24.0.3- Render in ME using Apple ProRes MXF format with the Apple ProRes 4444 with alpha preset- Install latest version of AE- Importing said MXF file will fail

Thanks for sharing the file via DM. I can import your file without any issues. Please try the following:

Run After Effects in Safe Mode and clear cache (Edit > Purge > All Memory & Disk Cache)
If you're importing the file from an external or server location, try importing it from a local location.

Let us know how it goes.

Thanks,

Nishu
