### FAQ

<details>

<summary><mark style="color:red;">Why does OpenAI only support full-text and sentence translation, and not subtitle translation?</mark></summary>

Open AI has been spending a lot of time on subtitle translation with unsatisfying results, and we are still trying to find a better solution. The main reason for inaccurate subtitle translation is due to sentence breaking. If the sentence breaking is optimized, the effect of using a custom translation engine will be better. We are still in the process of optimization, and we appreciate your understanding and support.
