I've had this problem for all of the versions of Media Encoder V14
When you add any form of Lumetri Colour Correction to any edit, Media Encoder crashes when you try to export.
My error log shows 'A low-level exception occurred in: AE.ADBE Lumetri (GPUVideoFitler::Render)'
This has only happened in V14 and I've never had this problem in any other version of Media Encoder.
If I revert to V13 it works fine but that isn't ideal.
Interstingly, you can export the edit without a problem directly from Premiere Pro by File - Export - Media - Export....
Any help really appreciated.
Have something to add?
