Currently, Cutback’s AI does not support transcribing multiple languages at once.
If your video contains more than one language, please use one of the following methods:
Set the language to A, transcribe and complete your edits, then apply the changes to Premiere Pro.
After that, set the language to B and transcribe again for the other language section.
Split the video by language:
Create one sequence with only the parts spoken in Language A, and another with only the parts spoken in Language B.
Transcribe and edit each sequence separately, apply changes to Premiere Pro, then combine them.
