Two paths to a movie you understand

SubPlayer first uses what is already in the file. If there are no subtitles, it creates the text from the audio.

Translate existing subtitles

If the file already has a subtitle track, pick a language and watch the translated text with the same timing on screen.

How to translate SRT

Create subtitles from audio

When there are no subtitles, SubPlayer recognises speech from the movie's audio on your computer and prepares the text for watching.

How subtitles are made

When you want to watch, not configure settings

The usual situation is simple: the movie is there, but the subtitles are in the wrong language or missing. SubPlayer shortens the path to watching and clearly shows which step runs locally and which needs the internet.

Open the movieThe app checks whether the file has subtitles.
Pick a languageTranslate the existing text or create a new one from audio.
Watch in the same windowAdjust timing, size and position while watching.

See clearly what happens to your file

The app separates what stays on your computer from what is sent for translation.

Quick answers before installing

Is the movie uploaded to a server?

No. The movie and audio stay on your computer. When translation is needed, the subtitle text is sent.

Does it work without internet?

Playback and speech recognition run on the PC. The subtitle workflow still needs either an active subscription licence or your Gemini API key, and translation needs internet access.

Why might Windows show a warning?

SmartScreen can warn about a new app or a publisher without an established reputation. Only download the installer from the official link and check the checksum.

Is this a professional subtitle editor?

No. SubPlayer is for preparing subtitles and watching a movie. For publishing or frame-accurate editing, choose a dedicated editor.

Open the movie. SubPlayer prepares the subtitles.

One-movie player trial, no card. Bring a Gemini API key for AI subtitles or choose a paid plan with cloud translation included.
