Subtitle translation in film and television dramas serves the purpose of conveying culture and promoting cultural exchange. When translating such works, it is crucial to grasp their unique characteristics.

Due to the influence of diverse ethnic cultures, customs, historical backgrounds, and other factors, subtitle translation involves a wide range of grammatical and syntactic expressions. This complexity can sometimes lead to loss of meaning during the translation process, potentially resulting in a lack of essential movie information. To effectively convey the information in the source language, translators often need to incorporate additional words and phrases. This ensures that the target language audience can experience the film in a manner similar to the source language audience. This practice of adding translation is a common strategy in subtitle translation. The additional subtitle information acts as a bridge between segments, supplements information, and interprets implied meanings.

Furthermore, to enable the audience to easily grasp the main information while watching the film, it is often necessary to delete certain sentence components during subtitle translation. Typically, the word count of movie subtitles is kept within one line. Non-essential language elements that do not align with the target language's linguistic norms, such as information conveyed visually or through the film's music, may be omitted without translation. This approach is known as subtractive translation, which prioritizes coherence in subtitles. Utilizing subtractive translation not only maintains the overall plot but also assists viewers in navigating subtitles, facilitating information absorption.

In summary, when translating film and television dramas, it is essential to consider the original author's intended meaning and strive to convey it accurately while ensuring smooth, coherent translation that aligns with the target language's cultural context. The translation should preserve the essence of the original language without altering its meaning, enabling the majority of target language readers to easily comprehend and engage with the content.
