Hi there,
Thank you for getting in touch!
When you encounter the Dubbing error, here's usually the way to solve the issue:
1) Selecting another Speaker's voice and clicking the Dub Video button (you can also try selecting the Clone voice back after that, it might help in case you need the Clone version and not the preset voice);
2) If it still doesn't work, you can re-upload the video and dub it again. In this case, feel free to send us a project link and we'll credit your account with additional minutes as compensation.
If you made some changes to the transcript, you can download the original/translated subtitles in SRT format by clicking the Download button in the initial project and then when re-creating the project, upload the SRT file together with your video.
Please keep us posted!
