Translate subtitles on your own computer

How subtitle translation works in Wolfcaps

In Wolfcaps, translation is the second step of one job. First, Wolfcaps makes the subtitles from the speech in your video (English, Hebrew or Russian), or uses text subtitles that are already inside the video file. You fix the original. Then you translate it.

The original and the translation stay side by side, line by line, with the same timing. You can read either one, or both together, while the video plays.

The translation runs on your computer, like the speech recognition. Your video and your subtitle text stay on your device.

How to translate subtitles with Wolfcaps

1. 1Open Video → subtitles and drop your video.
2. 2Let Wolfcaps make the subtitles (see the auto subtitle generator). If the video already has text subtitles inside, Wolfcaps finds them and uses them instead.
3. 3Read through the original and fix mistakes first. The translation can only be as good as the text it starts from.
4. 4Click Translate…. Wolfcaps first asks Finished editing? Choose Yes, translate when the original is final.
5. 5Pick the language and choose Fast or Best. The first time, the translation model downloads once and stays in your browser.
6. 6Check the result. Switch the view between Original, Translation and Both, and click any line to fix it.
7. 7Click Export… to save an SRT, VTT, ASS or TXT file in either language, or the video with the original and the translation as tracks.

Fast or Best

Wolfcaps has two ways to translate. Both run on your device.

• Fast.

  A translation model: about a 1.8 GB download, and quick to run.

• Best.

  AI with a names glossary: about a 3.4 GB download, and slower.

Before it translates, Best builds a glossary of the names and terms in your subtitles, to help keep them consistent from line to line. You can see the glossary in the Full editor, change a translation there, and add your own terms.

Pick Fast when you want a translation quickly. Pick Best when you have the time, and especially when the video is full of names.

Edit, then update the translation

Translation is offered after the subtitles are made, for a reason: if you change the original after translating, those lines need to be translated again.

Wolfcaps keeps track of this for you. It remembers which original text each translated line came from. If you change lines in the original later, an Update translation button appears, with the number of lines that changed. It translates only the lines you changed and leaves the rest as they are.

Languages

You can translate subtitles into 20 languages: English, Hebrew, Russian, Arabic, Spanish, French, German, Portuguese, Italian, Ukrainian, Turkish, Polish, Dutch, Chinese (Simplified), Japanese, Korean, Hindi, Persian, Indonesian and Vietnamese.

We've checked translation quality for English, Hebrew and Russian. For the other languages, quality isn't verified yet, and Wolfcaps tells you so when you pick one. Ask someone who speaks the language to read it before you publish.

What to know before you start

• Wolfcaps translates subtitles that come from a video or audio file: the ones it makes from the speech, or text subtitles already inside the video. It doesn't open a separate .srt file on its own.
• Subtitles stored as pictures inside a video, as on some DVD and Blu-ray copies, can't be read as text. Transcribe the speech instead.
• Speech recognition works for English, Hebrew and Russian only, so that's the language your video needs to be in, unless it already has text subtitles.
• Machine translation makes mistakes, especially with jokes, slang and names. Read it through before you publish.
• You need a computer with Chrome, Edge, Brave or another Chromium browser, or Safari 26 or newer on a Mac, and a GPU the browser can use (WebGPU).
