Video Translation: Transcription & Generative AI is Recommended

Automatic video translation is convenient when you want to watch foreign language videos or add foreign language subtitles to your own videos.
However, previous video translation methods had their drawbacks.
YouTube's automatic translation subtitles are easy to use, but since they are auto-generated, they often contain mistranslations, which can significantly alter the meaning.
Also, Google Translate translates mechanically sentence by sentence, often resulting in unnatural phrasing because it doesn't consider the surrounding context.
That's why we recommend creating an SRT file with the AI transcription app Mr. Transcription and then translating it with generative AI.
Generative AI translates by understanding the overall flow of the subtitles, resulting in higher quality text.
Furthermore, Mr. Transcription is a free Japanese website that can be used for commercial purposes.
You can create video subtitles using just your iPhone.
