Is there any feature/plugin that allows me to import and export labels in other files like
subtitle files (sct file) for DVDs
or CUE Files
It whould be much easier to create a subtitle file for DVDs by using audacity because you can “see” the dialoges to find the right moment to start and stop the text.
You may be able to use a spreadsheet application such as Microsoft Excel, or a scripting language such as Python, to convert between labels and other formats.
