Nine reasons to make your English subtitles here.
Not a feature list — the things that decide whether your video ships captioned today.
Start from any video you have
- Upload or paste a linkMP4, MOV, MP3, M4A — or a public YouTube, Instagram or Facebook URL.
- Long files welcomeUp to 8 hours and 30 GB per file, on every plan.
- Record in the browserCapture the screen or your voice with nothing else installed.
- Bring subtitles you haveImport an .srt or .vtt and translate or edit from that.
Pick the subtitle languages once — 95+ to choose from
- Any source, any targetTranscribe the spoken language, then translate into as many targets as you need.
- One track per languageEach language becomes its own subtitle track you can open, edit and export.
- Mixed-language speech holds upCode-switched sentences come out in one clean cue, not two broken ones.
- Bilingual pairsSource and translation can ship together in a single subtitle file, cue by cue.
The file the platform asks for
- Subtitle filesSRT and VTT, single-language or bilingual.
- Text and tablesTXT, DOCX, XLSX or Markdown, timestamps included.
- One ZIPEvery format in a single download.
- Share linkSend the result to a reviewer — no account needed on their side.
Proofread before anyone reads
- A score out of 100Suggestions sorted by kind, usually in ten to thirty seconds.
- Approve by groupApply the groups you agree with; the rest is left exactly as it was.
- Timings never moveMisheard words and punctuation get fixed without the cues shifting underneath.
- Entirely optionalNothing is applied until you press the button.
Hallucinated lines get caught, not shipped
- Two detectors, not oneAI hallucination detection and engine-side checks run on every chunk, so invented text is flagged where it happens.
- Automatically re-runA flagged segment goes back through a different engine instead of landing in your file.
- Silence stays silentA pause is a pause, not a sentence the model imagined.
Captions that look like your channel
- Two caption stylesOutline and shadow, or a background box with its own opacity.
- Styled per trackPrimary and secondary styled separately, so bilingual subtitles stay readable.
- Adaptive font sizeLong lines stay inside the frame instead of running off the edge.
- Previewed on the frameFont, size, colour, alignment and margin, shown on the real still as you set them.
Need the finished video? Burn it in, up to 4K
- Up to 4K720P, 1080P, 2K or 4K, with the style exactly as you set it.
- Bilingual burn-inTwo languages stacked on one frame, each styled separately.
- Your watermark, or noneHide the default one entirely, or replace it with your own.
- Renders in the backgroundKeep editing; the job uses a snapshot from when you pressed render.
Your names survive the subtitles
- Mark a term universalPeople, products and jargon come back spelled your way in every track.
- Or pin it per languageWhen a market really does use another name, set that rendering just for it.
- A workspace glossaryApplies automatically, on every project you start.
- Import or extractLoad terms from CSV or XLSX, or let the AI pull candidates out of a PDF.
The same pass writes more than subtitles
- Chapters and quotesReal timestamps and the lines worth pulling, ready to paste.
- Description and tagsThe upload copy comes off the same transcript.
- Summaries, translatedThe second market gets more than translated captions.
- Ask the videoEvery answer points back at the cue it came from.
If your video needs English subtitles, this is for you.
Four situations, one need — accurate English subs, timed and ready to publish.
Going global
Non-English channels
Videos in any of 95+ languages get English subs — translated cue by cue, bilingual on screen if you want both.
Lessons & lectures
Course & training teams
Recorded sessions become readable, searchable and captioned; hours-long files process in one pass.
Demos & webinars
Business teams
Product names spelled right via the glossary, captions styled to the brand, video exported ready to send.
And the rest of it.
None of these are the reason to switch, but every one of them is there when a delivery spec asks for it.

See it in the productQuestions people askbefore they hand over a video
Upload the video or paste a public YouTube, Instagram or Facebook link, pick English, and the AI transcribes the speech into timed cues. Review, fix anything, then download the file or burn the captions into the video.
Yes — this is how 'eng sub' actually gets made. The AI transcribes the spoken language (any of 95+), then translates into English. It works on video files you have: your footage, licensed content, interviews — Subanana holds no library of ready-made subs for shows or movies.
Overall accuracy reaches 98%. Every chunk passes two hallucination checks — silence stays silent instead of becoming an invented sentence — and an optional proofread pass proposes misheard and same-sounding words for you to approve, without moving a single timestamp.
SRT, VTT, TXT, DOCX, XLSX and Markdown — single-language or bilingual, or one ZIP with everything. You can also export the video itself with the English captions burned in, up to 4K.
No. Font, size, colour, outline or background box, position and margin are all yours to set, previewed on the real frame — and a saved style template applies to every video after this one.
A free account previews the first 15 minutes of each file, 3 files a month, no credit card. Downloading the subtitle file is a paid feature — you check the quality before paying anything.
