It is stuck here, just says "exporting video: preview not available"
Sorry about that. Does it happen with a specific project? Do you have any third-party plugins?
Could you also try some methods mentioned here? https://helpx.adobe.com/after-effects/kb/after-effects-composition-export-error.html
Let us know.
Hi there, sorry to hear you are having problems. In order to help you I need more information like AME and Ae version used? Is your issue reproducable? Where are the files located? Is AME still responsive or does it hang? If it hangs, could you provide a spin dump file of the hanging AME?
