Why do I have to create captions in the source language of the video?

It is always necessary to create captions in the original language of a video before generating an automatic translation. If we went straight to the translation, the result would be of lower quality. And in case you have several languages, some modifications would have to be made on each foreign language. Our platform must generate captions in the original language before generating an automatic translation. For this reason the credits are debited for each language created. We remain available if you have any questions.

How long are my credits valid?

The credits you buy are valid for one year.

How can I top up my account by buying credits?
