How it works

Three steps, no editing software and no subtitle files to write.

1

Upload your video

Drag in an MP4, MOV or WebM up to 500MB. The speech is transcribed and timed for you — vertical and horizontal videos both work.

2

Pick a style and position

Choose from 29 caption styles, then drag the caption band over your video to set exactly where the text sits.

3

Generate and download

Captions are burned into the video itself, so they show up everywhere — no separate subtitle file, no watermark.

Captions that actually get watched

Most social video is watched on mute. Captions aren't a nice-to-have any more — they're the difference between someone stopping on your video and scrolling past it. But adding them by hand is the slowest part of editing: transcribe, time each line, style it, then do it again for the next video.

VdoZen's subtitle generator does that whole pass for you. Upload the video and the audio is transcribed and timed automatically. You pick how the captions should look, drag them to where you want them on the frame, and download a finished video with the captions burned in.

Burned in, not a sidecar file. The captions are rendered into the video frames themselves. That matters because most platforms either ignore uploaded subtitle files or hide them behind a settings toggle most viewers never touch. Burned-in captions show up for everyone, everywhere, including reposts and downloads.

29 caption styles

Different content wants a different look, so the style list spans the range rather than giving you one house style:

  • Clean and readable — full lines in bold white with an outline, or classic karaoke where each word lights up as it's spoken.
  • Punchy and social — big bold caps with the key word highlighted, stamp-style phrases that slam onto the frame, comic bounce-in captions.
  • Cinematic — focus blur that keeps the spoken word sharp while the rest of the line softens, or gold-and-cyan glow text with a halo.
  • Playful — automatic emoji that bounce in above the words, chat-bubble captions for POV and storytime, letter-by-letter typewriter with a blinking cursor.

Five styles are available on the free plan, with the rest unlocking on paid tiers. Every style is previewed as a live animation before you pick it, so you're not guessing from a name.

Position captions where you want them

Automatic caption placement usually means "bottom centre, hope it works." That falls apart the moment your video has a logo in the corner, a talking head low in the frame, or a platform UI overlay eating the bottom third.

After uploading, a caption band appears over your actual video frame. Drag it up or down to set the vertical position, and that placement is applied at the right scale for your source resolution — so the same choice looks correct on a 1080×1920 vertical clip and a 4K landscape one.

What it costs

Captioning is priced by video length and costs a small number of tokens per run — you see the exact cost before you generate, based on the real duration of the file you uploaded. New accounts get free tokens on signup with no credit card, which is enough to caption a video and see the output quality for yourself.

There is no watermark on any plan, free included.

What you get for free

Every new account starts with 100 tokens — no credit card, no trial timer. That's enough to generate a short video, caption a clip, or run a batch of voiceovers and see the real output quality before spending anything.

You also get a referral code you can share. When someone redeems it, you both get the Starter tier with 400 tokens — more voice actors, more caption styles, and the higher-quality generation modes. It's a genuine two-way reward, not a discount code.

Tokens are shared across every tool, so the same balance covers video generation, captions, clipping, voiceovers and SEO. Nothing you export carries a watermark on any plan, free included.

Frequently asked questions

Is the subtitle generator free?

Yes — you get free tokens when you sign up, with no credit card required. A short video costs only a few tokens to caption, so you can try the full flow before deciding whether to buy more.

Do the captions have a watermark?

No. Videos you export from VdoZen have no watermark on any plan, including the free tier. What you download is what you can publish.

What video files can I upload?

MP4, MOV and WebM files up to 500MB. Both vertical (9:16) and horizontal (16:9) videos are supported, and captions are scaled to match your source resolution automatically.

Can I choose where the captions appear?

Yes. After uploading, drag the caption band up or down over your video to set the vertical position. The placement is applied at the correct scale whatever resolution your source video is.

How many caption styles are there?

29 styles, from clean single-line captions to karaoke fills, word-by-word highlights, emoji pops and typewriter effects. Five are available on the free plan and the rest unlock on paid tiers.

Does it transcribe the audio automatically?

Yes. Upload your video and the speech is transcribed and timed automatically — you don't need to write or upload a subtitle file.
