With Smartcat’s AI-human collaboration, every translation benefits from both AI automation and expert refinement, resulting in superior content translation that improves over time.

To create an SRT file, use a text editor or subtitle editing software. Enter the sequence number, start and end time codes (hours:minutes:seconds,milliseconds), then the subtitle text. Save with a .srt extension. To use the SRT file, match its name to the video file and place them in the same directory. Most video players will detect and display the subtitles automatically.

With Smartcat, you simply upload your SRT file, pick your target language, and let our AI agents provide an initial translation. Reviewers can then refine the translation within the Editor to confirm accuracy and train the AI if necessary. Once finalized, you can save and download your SRT file in the new language.

If you need subtitles embedded in a video in SRT format, extract the subtitles using video editing or subtitle extraction software. After extraction, save the subtitles as an SRT file.

Some tools let you export directly to SRT format, while others may need manual formatting to ensure proper sequence numbers, time codes, and subtitle text.

Smartcat’s AI agents combine AI translation engines, translation memories, and glossaries to deliver high-quality, consistent SRT translations. With Smartcat’s AI-human collaborative workflows, each translation benefits from AI automation and expert input, improving over time.
