I have received permission from someone to translate the audio in their movies. The problem I am facing is that the video quality is quite poor and the author does not have the original videos any more.
How can I replace the audio in the YouTube videos without further degrading the quality of the videos?
Thanks,
Tom
Answer
You can’t, sadly.
YouTube allows you to swap audio with their list of provided songs, but other than that you are stuck with it.
Only option is to re-upload the same video with the sound you desire.
