How it works

Three steps, not one more

1

Upload your video

Pick the spoken language, or let flysub detect it, then the language of the subtitles: a search box over 98 languages.

2

Check the translation in the editor

The speech is transcribed, translated sentence by sentence with the whole video as context, then cut back into subtitles on the same timing. Fix any word, switch between the original and the translations, or add another language, even on a video you already subtitled.

3

Export

MP4 ready to post, or transparent MOV for your edit.

Video translation questions

How do I translate the subtitles of a video?

Upload the video to flysub, choose the spoken language (or let it be detected) and the language you want the subtitles in. flysub transcribes the speech, translates it sentence by sentence with the whole video as context, and cuts the result back into subtitles synced to the voice. Pick a style, check the text in the editor, then export an MP4 with the translated subtitles burned in, or a transparent MOV to overlay in your editing software.

Does flysub translate the voice too?

No. There is no dubbing and no translated voice: the audio stays exactly as recorded, in its original language. Only the subtitles are translated. That is the fastest way to make a video readable by an audience that does not speak its language.

Which languages can I translate into?

98 languages. The most requested come first in the list: French, English, Spanish, Portuguese, German, Italian, Dutch, Polish, Romanian, Turkish, Russian, Ukrainian, Arabic, Persian, Urdu, Hebrew, Hindi, Marathi, Bangla, Tamil, Telugu, Malayalam, Thai, Vietnamese, Indonesian, Korean, Japanese, Chinese, and 70 more, with a search box to find yours. The spoken language of the video is detected automatically, or you can set it among 28 languages.

Is the translation accurate?

It is a machine translation by an AI model, done sentence by sentence from the original transcript with the whole video as context, so each line matches what is said at that moment. Read it once in the editor before exporting: you can fix any word, and your custom dictionary keeps your names and brands spelled right.

Do the translated subtitles keep the word-by-word timing?

Yes. Each translated sentence keeps the time slot of the original one, its words are spread over that slot, and the result is cut back into subtitles, so karaoke and highlighted words still follow the voice.

Can I translate a video I already subtitled?

Yes. Open it in the editor and pick a language: the translation is added as a new version of the project, next to the original. You can switch between the versions you already have at any time.

How is a translated video counted?

Translation is included in every plan, free trial included (with its watermark). Importing a video with a translation counts as one video, exactly like a subtitled one; each further translation from the editor, into another language or again, counts as one more video. Switching back to a version you already have, the original or a language already translated, is free. The free trial includes 3 videos.

How long can the video be?

3 min on the free trial, 3 min on Creator, 5 min on Pro and 15 min on Studio.

Is there a watermark?

Only on the free trial. Every paid plan exports without a watermark.

Will the final render really match the preview?

Yes, down to the pixel: the preview and the export are produced by the same rendering engine. What you see in the editor is exactly the file you download.
