What does this video subtitle generator do?

It auto-creates timed soft captions from your video’s speech, then lets you download SRT or VTT. The focus is caption generation in the spoken language; translation is optional afterward.

How is this different from the homepage translator?

The homepage emphasizes generate-and-translate across many languages. This subtitle generator page is optimized for speech → original soft captions first (auto-detect + original), with translation as a follow-up step.

Can I generate an SRT without translating?

Yes. Keep the target on original language and run Generate. You will get a soft SRT/VTT in the detected spoken language without a cross-language translation pass.

Does the generator burn subtitles into the video?

No. Output is a separate soft track. If you need burned-in text, import the SRT/VTT into CapCut, Premiere, Final Cut, or similar after download.

Do I need an existing caption file to start?

No. Upload the video itself. The subtitle generator builds cues from audio — you do not paste an SRT to begin.

Which languages can it auto-detect?

Speech recognition auto-detects a wide range of spoken languages for caption generation. After you have a track, you can optionally translate soft subtitles into 40+ target languages in the workspace.

What file types and limits apply?

MP4, MOV, and WebM are supported in the browser uploader. Clips must be 10 minutes or shorter and under 200 MB.

When do credits get used on Generate?

Credits apply when Whisper transcription is required — typically 1 credit per second of video. New users get 600 free credits (~10 minutes). Reusing a cached transcript for a new target language often does not re-charge Whisper. Unlimited is a subscription entitlement, not free unlimited Whisper without a plan.

Will generated captions stay in sync?

Each cue includes start and end times so the soft track aligns with speech when loaded in YouTube, browsers, or editors. Always spot-check important lines before publishing.

Can I edit lines after generation?

Yes. Soft subtitle files are editable text. Adjust wording or timing in the workspace export, an SRT/VTT editor, or your NLE.

Are uploaded videos stored?

No. Files are processed to generate captions and are not kept as a personal media library. See the Privacy Policy for details.

What if I need Japanese → English specifically?

Use the Japanese to English subtitles landing for that pair preselected. This page stays focused on general subtitle generation from any supported spoken language.

How this subtitle generator builds captions

This video subtitle generator is built for caption creation — not translation-first workflows. Drop a video, let speech recognition write timed cues in the spoken language, preview them in the workspace, then export soft SRT or VTT. Translation into other languages is optional after the track exists.

Step 1
Upload a video for captioning
Sign in, then add MP4, MOV, or WebM (max 10 minutes / 200 MB). New users receive 600 free credits for speech-to-caption generation.
Step 2
Auto-generate timed soft subtitles
The subtitle generator detects speech, writes cues with timestamps in the original language, and shows them beside your preview.
Step 3
Export SRT/VTT — translate later if you want
Download soft subtitle files for publishing or editing. Optional translation into 40+ languages is available after the original track is ready. Uploads are not stored.

Subtitle generator results on real clips

Two short examples of what an online subtitle generator can produce: clear timed captions aligned to speech, ready to download as soft subtitle files.

Dialogue clip → timed captions

Example of spoken dialogue turned into readable timed captions — the soft-subtitle style this generator exports as SRT or VTT.

Talking-head → caption track

Example of a talking-head video with timed captions generated from speech, ready for soft-file download.

What is a video subtitle generator?

A video subtitle generator listens to dialogue (or voice-over), places start/end times on each line, and writes a soft caption track you can toggle, edit, or import into YouTube and editors. It solves “I need an SRT from this MP4,” not “I already have an SRT and only want to translate it.”

Searchers looking for a subtitle generatoror auto subtitle generatorusually want original-language captions first. This page defaults to auto-detect + keep original. Cross-language translation is available afterward in the same product if you need it.

What a subtitle generator should export

Good online subtitle generators prioritize soft tracks you can revise. Hard burn-in is a later editing choice — not the default deliverable here.

Soft output (this generator)

Creates an external timed caption file from speech
Viewers and editors can enable, disable, or restyle the track
Ideal when you still need wording or timing fixes
Imports cleanly into YouTube Studio, CapCut, Premiere, and LMS players

Hard burn-in (not the default)

Pixels permanently stamped onto every frame
Cannot be turned off without a new video encode
Useful for some social apps that ignore external tracks
Do burn-in in your editor after you download soft SRT/VTT from this tool

Subtitle generator capabilities

Focused on turning audio into a usable soft caption file quickly — with credits that only apply when transcription runs.

Speech-to-subtitle, not paste-to-translate

Start from video audio. The generator creates the caption track so you are not typing every line by hand.

Original-language first

Defaults to auto-detect source and original target — ideal when you searched for a subtitle generator rather than a language pair.

Soft SRT & VTT downloads

Export timed external files for YouTube and editors. Burn-in is intentionally left to your own tools.

In-workspace cue review

Check wording and timing against the video before you download, so the first export is closer to publish-ready.

Credits tied to transcription

When Whisper must run, usage is 1 credit per second. New accounts get 600 free credits (~10 minutes). See Pricing for Lite, Unlimited, or pay-as-you-go.

No personal video library

Uploaded media is used to generate captions and is not retained as stored user content.

Who needs a subtitle generator?

Anyone publishing video who starts without a caption file — not only teams that already work with bilingual SRTs.

YouTubers adding first captions

Generate an SRT from the uploaded video, review lines, then attach the soft track in YouTube Studio.

Course and training videos

Create accessibility captions for lessons without waiting on a full manual transcription pass.

Podcasts and interviews on video

Turn spoken segments into timed cues for clips, trailers, or full-episode uploads.

Social cut-downs

Generate a caption file for short excerpts before you decide whether to burn text in CapCut or Reels tools.

Agencies delivering caption packages

Produce soft SRT/VTT deliverables clients can restyle — without locking text into the master.

Teams that might translate later

Generate the original track now; open a translation target afterward if a second language is required.

SRT and VTT from your video

After generation, download the format your destination expects. Both are soft subtitle formats produced by the same caption pipeline.

SRT for editors & YouTube

The most common deliverable when people say “generate SRT from video.” Use SRT for YouTube uploads, Premiere, Final Cut, DaVinci Resolve, and most desktop caption tools.

VTT for web & HTML5

Choose WebVTT when the player is a website, course platform, or browser-based video element that expects a .vtt track beside the media file.

Quick start: generate subtitles from a video

Use this checklist when your goal is caption generation — “video subtitle generator,” “auto subtitle generator,” or “MP4 to SRT.”

1. Keep the clip short and audible. Stay within 10 minutes and 200 MB. Cleaner speech yields cleaner auto-generated cues. On credit plans, transcription uses 1 credit per second of video.
2. Upload on this subtitle generator page. Sign in with Google (new accounts include 600 free credits ≈ 10 minutes). Source stays on Auto detect; target stays on original language so you generate captions first.
3. Run Generate and review cues. Speech recognition builds timed soft subtitles. Skim lines in the workspace against the video preview before you export.
4. Download SRT or VTT. Take the soft file into YouTube, your NLE, or CapCut. Burn-in is optional and happens outside this generator.
5. Translate only if needed. If you later need another language, change the target in the workspace. Cached transcripts can be reused without re-charging Whisper in many cases.

Why generate soft captions first

Starting with a subtitle generator keeps your master video clean and your caption file editable.

Ship captions without re-encoding. Export a track instead of baking text into every frame of the master.
Reach muted and accessibility audiences. Timed captions help social viewers and deaf or hard-of-hearing audiences follow speech.
Fix wording after generation. Soft SRT/VTT files are plain text — adjust names, jargon, or timing before publish.
Keep uploads private. Videos are processed to create captions and are not kept as a personal media library.
