Which subtitle formats are supported?
You can upload common formats like SRT or ASS and export your translations as SRT, ASS or a hardcoded video. Starting from a raw video is also possible – the studio generates subtitles first.

Why translate subtitles instead of re-recording?
Re-shooting or dubbing every video is expensive and slow. Subtitle translation lets you keep your original visuals and voice – and still speak your viewers’ language.
🌍
Turn one video into many markets
Take a single master video and localise it into English, German, Spanish, Japanese and more – without spinning up a full production for each language.
🧠
Keep meaning, not just words
Good subtitle translation is about nuance, timing and line length. AI gives you a strong first draft – the editor lets you keep punchlines, tone and pacing exactly right.
⚡
Ship in days, not weeks
Batch-translate your existing catalog and go live in a few days – instead of waiting for manual translation and versioning for every single upload.
How to translate subtitles online with Subvideo.ai
Start from a raw video or an existing SRT file – the studio takes you from first upload to finished multilingual subtitles in a few clear steps.
1. Upload your video or subtitle file
Drop in MP4, MOV, MKV or upload SRT / ASS. If you start from a video, Subvideo.ai auto-generates accurate subtitles as your source layer.
2. Clean up the original once
Edit wording, fix typos and adjust timing in the source language. Every translation that follows benefits from this one clean master track.
3. Pick your target languages
Select the languages you want to support – for example English, German, Spanish, French, Portuguese, Japanese or Korean – and let AI generate the first pass.
4. Translate subtitles with AI – side by side
See original and translated subtitles next to each other. Keep nuance, brand terms and humour by editing sentences inline while the timing stays in sync.
5. Adjust length, reading speed and style
Different languages need different space. Shorten lines, split long phrases and adapt style so subtitles stay readable on phones and widescreen.
6. Export SRT, ASS – or hardcoded video
Download classic subtitle files for YouTube, players and LMS – or burn the translated subtitles straight into an MP4 if you need a final, platform-agnostic file. Learn more about burning subtitles into your videos.
Try it with your video or SRT file
Upload a video or subtitle file, let AI create and translate your subtitles and you will be redirected to the editor as soon as processing is done.

FAQ: Translating subtitles online with Subvideo.ai
A few quick answers so you know how formats, timing and privacy work before you upload your first file.
Can I translate directly from a video?
Yes. If you do not have a subtitle file yet, Subvideo.ai first creates subtitles from your audio and then uses them as the base for translation.
Does AI translation respect timing?
The timing of each subtitle line stays aligned with the original. You can still tweak timestamps if you want to tighten cuts, shorten pauses or improve reading flow.
Can I keep multiple languages for one video?
Absolutely. You can export several subtitle files in different languages for the same video – or create separate hardcoded versions if platforms do not support soft subs.
Is my data stored permanently?
No. Files are stored only for processing and a short retention window so you can review and download results. After that, they are removed automatically from EU servers according to your privacy settings.
