Examples

Prompt

Translate my .srt subtitles from English to Spanish for the movie I just downloaded.

Output

Sure! I'll run the subtitle translation from English to Spanish using the `scripts/translate.py` script. Please provide the path to your input file, e.g., `movie_en.srt`, and specify the output filename, such as `movie_es.srt`. If you have any proper nouns or technical terms, consider creating a glossary.json to ensure accurate translation. Once I have these details, I'll process the translation and return the translated subtitle file.

Prompt

Can you convert these captions from Japanese to French? The file is captions_jp.srt.

Output

Absolutely! I'll execute the translation from Japanese to French on `captions_jp.srt`. If there are specific names or terms to preserve, please prepare a glossary.json and share its path. I'll run the `scripts/translate.py` with the appropriate parameters, handle chunking for speed, and provide you with the translated `captions_fr.srt` file once complete. Remember to review the output for accuracy after translation.
