Translate videos online into editable subtitles with EasySub. Upload a video or subtitle file, or paste any YouTube or video URL, choose the language spoken in the recording and the language you want, then generate both the source and translated subtitle tracks. You can review each line beside the video before downloading subtitles or exporting a captioned video.
Use the video translator for YouTube videos, tutorials, interviews, courses, podcasts with video, product demonstrations, marketing clips and social content. To translate a video into English, select the language actually spoken as the source and English as the target. If you only need captions in the original language, use the AI Subtitle Generator.
How to translate a video online
- Add the video, audio or subtitles. Start a new subtitle project and upload your local file, paste any YouTube or video URL, or upload an existing SRT subtitle file.
- Choose the source and target languages. Select the language spoken in the video, turn on Add translation, choose a translation model, and select the language you want. Automatic language detection is available when the source language is unknown.
- Generate and review both tracks. EasySub creates timed source subtitles and the translated track. Play the video while checking names, numbers, terminology, meaning, line breaks and timing in both versions.
- Download or export. Choose Translated only, Source only or Bilingual when downloading subtitles. Export SRT, VTT, ASS or TXT, or render a video with the selected captions displayed.
Translate a YouTube video from any URL
Paste any YouTube or video URL into the URL upload field and use the same translation workflow as a local file. Select the spoken language and target language before generating the subtitles, then review the result in the editor. This is useful when you want English subtitles for a foreign-language YouTube video, translated captions for your own channel, or reusable subtitle files for another player or publishing platform.
You can also upload a local video when that is more convenient. The workspace accepts common video formats including MP4, AVI, FLV, MOV and MKV, and audio formats including MP3 and WAV. For an audio-only recording, the Audio Translator provides a focused version of the same transcription-and-translation workflow.
Translate an existing SRT subtitle file
If a video already has subtitles, upload the SRT file and translate its text without rebuilding the project from the beginning. Keep the existing timestamp structure, check that every translated line matches the intended scene, and adjust line breaks when the target language is longer or shorter than the source. You can then export translated-only or bilingual subtitles for review and delivery.
An SRT upload is especially useful when the source subtitles have already been checked by an editor. It separates source transcription work from translation work and gives translators a stable timed script. If you want a dedicated subtitle-file workflow, see the Subtitle Translator.
Video translation in more than 150 languages
EasySub supports more than 150 languages in its subtitle workflow, so one video can be prepared for viewers in English, Spanish, French, Portuguese, German, Italian, Japanese, Korean, Arabic, Hindi, Vietnamese and many other languages. The available source and target choices appear when you create the project.
Select the language spoken in the recording as the source and English as the target. Review names, technical terms and idioms that may need a natural English equivalent.
Select English as the source and the audience language as the target. Keep product names and brand terms consistent across every subtitle line.
Use the bilingual download option when viewers, reviewers or language learners need the source and translated text together.
How accurate is automatic video translation?
For clear recordings, EasySub automatic source subtitle generation can reach over 90% accuracy. The final translation also depends on the quality of that source transcript. Background noise, overlapping speakers, strong accents, low recording volume, names and specialist vocabulary can affect the result, so the editor keeps the video, source subtitles and translated subtitles together for review.
Start by checking the source track against the recording. A translation can be fluent but still repeat a misheard number, name or negative. Then review the translated track for meaning, tone and terminology. Replay the subtitle timing after edits, and preview longer translated lines on a small screen so they remain easy to read.
Download translated subtitles or a captioned video
| Output | What it contains | Best for |
|---|---|---|
| SRT | Translated subtitle text with timestamps | YouTube, media players and editing tools that accept standard subtitle files |
| VTT | Translated subtitle text with web-compatible timestamps | Web players and platforms that use WebVTT captions |
| ASS | Timed subtitle text with styling information | Compatible players and editing workflows where subtitle styling matters |
| TXT | Readable source or translated text without subtitle timestamps | Scripts, notes, content reuse and text review |
| Captioned video | A rendered video with the selected subtitles visible | Publishing a video where captions should remain part of the picture |
When a project contains a translation, Download subtitles offers Bilingual, Source only and Translated only. Choose the version required by the destination platform. SRT, VTT and ASS preserve subtitle timing; TXT is plain readable text and does not contain subtitle timestamps.
Video translation checks before publishing
Check names, numbers, units, instructions, idioms, branded terms and industry vocabulary. Keep repeated terms consistent throughout the video.
Replay edited lines, split long sentences, avoid crowded bilingual captions and give viewers enough time to read each subtitle.
Preview accents, right-to-left text and non-Latin characters in the final player or exported video. Confirm captions do not cover important visuals.
For detailed line-by-line timing and text changes, open the Subtitle Editor. If you need to create original-language captions before deciding whether to translate, begin with the Auto Subtitle Generator.
Can I translate videos for free?
Yes. Free EasySub accounts receive a fixed 30 minutes of processing each month. You can use the allowance to create and translate subtitles, review the result in the editor, and choose the output needed for your project. The workspace shows your remaining time and current account options.
