How are the hard subtitles in the video recognized and translated into French?

I am a short video content creator,I often spend a lot of time extracting copy, modifying it and translating it for content creation in the process of video translation i, so I need an AI tool that can automatically extract video copy and apply chatgpt to localize and translate video copy, I finally found GhostCut, a tool that automatically identifies the hard subtitles in the video and translates them into the language of each country, and the most important feature is that they apply the chatgpt interface in the translation process, and can automatically synthesize with the original video, and if there are unwanted hard subtitles in the video, you can also use the subtitle removal function to remove them, this product have launched ;
