You're ingesting dailies that have been backed up earlier. You have properly imported the backup drive, selected the destinations in the ingest tab. Edge processed most of the files, but refuses to transfer one or more files with the following message. "Validation failed, transcoded version has a different duration".
This is because the length of the transcoded clip is not what you would expect. Either the clip was altered between backup and ingest, or the metadata of the file are corrupt. In either case there is a potential problem.
To solve the problem, please check the length and the content of the original files and manually ingest them.
