Known and fixed issues in Adobe Premiere

Summary

Export from Premiere or Adobe Media Encoder can stop responding at the “Validating ingredients” step when the sequence contains AI-generated media with Content Credentials that list a very large number of ingredients. Encoding never starts, and no error is shown. Turning off Content Credentials in Preferences or on the Export screen doesn't prevent the issue because Content Credentials are always applied to exports containing AI-generated media.
