DO IT YOURSELF
You can use the following tools, if you are not paying a professional human captioner. But please be aware that we don't accept A.I. generated captions without human corrections. You must do your own manual edit after you have used A.I..
Upload your low quality video, generate subtitles and auto-translate into English. You should also manually go through the subtitles and edit grammar and vocabulary because you cannot trust the A.I. - There is no accuracy with this tool. It's just help.
If the subtitles of your movie are in a DOCX or EXCEL or TXT file, you can use other free tools to convert them. Try out the following websites or check yourself on Google and Baidu.
