# Add Text to Video: Put Text, Titles & Logos on Video

Put text on video, timed titles, lower thirds, and your logo or watermark on any MP4 or MOV.

## How it works

1. Add your MP4, MOV, or WebM video, then pick a text style: a title, a lower third, a headline, or a label.
2. Type your words and drag them onto the canvas, or pin them to a corner. Add a PNG or WebP logo watermark the same way.
3. Set when each text or logo shows on the timeline, play it back, then press Export to download the MP4.

## Titles, lower thirds, and watermarks where viewers look

Audo adds text, titles, lower thirds, and PNG or WebP logo watermarks to MP4, MOV, MKV, WebM, and AVI videos up to 2 GB without an account, with the first 10 minutes free, 10 times a day, and no sign-up. Because social feeds start playing on mute, a clear headline in the opening seconds, a speaker name in a lower third, or a persistent channel watermark often decides whether someone keeps watching.

The live canvas preview in the editor uses the exact same font and layout renderer that produces your exported H.264 MP4, while keeping your original resolution, frame rate, and soundtrack intact.

Tool: Add text and logo (`add_overlay`). Price: 1 credit a minute — $0.01/min ($0.60/hr), with no subscription — of input for whole files, charged only when a job succeeds.

## Free API

```bash
curl -F file=@clip.mp4 -F logo=@logo.png -F 'overlay={"version":1,"items":[{"type":"logo","position":{"anchor":"bottom_right"},"scale":0.15,"opacity":1,"margin":0.04,"start_ms":0,"end_ms":3000}]}' https://audo.ai/api/try/add-overlay -D response.headers -o response.body
```

Read response.headers and response.body before naming media. Handle 202, 200 JSON and errors with the complete response client at https://audo.ai/docs/api?utm_source=markdown&utm_medium=agent#responses.

Free for the first 10 minutes of each file, 10 times a day per person, with no key or account. Uploads up to 10 GB, 2 at once from one address. The response is the result itself; a job that runs longer than about 30 seconds returns 202 with a link to check on it. With an API key (`-H "Authorization: Bearer $AUDO_API_KEY"`), omitting free runs the whole file with credits if the balance covers it, otherwise the free portion if quota remains. Set free=true to prohibit spending; for paid whole files use free=false with an approved positive max_credits. A free result cut short comes with finishUrl (and the Audo-Finish-Url header when the response is the file itself): give it to the person, who pays there (from $5, no sign-up), and the whole file runs; keep checking the status link, whose finishedBy names the whole-file job and its own status link.

## Options

Form fields with the same names as the MCP tool's inputs:

- `overlay`: OverlayDocument v1: timed text and logo items; end_ms is exclusive. Positions are item centers, or a nine-grid anchor with margin. Sizes use frame height; logo scale uses frame width.

## Languages

Any language: it works on the sound, not the words.

## From an assistant (MCP)

Add https://audo.ai/mcp and sign in (setup for each assistant: https://audo.ai/setup.md). The tool is `add_overlay`:

> Adds timed text and logos to video using OverlayDocument v1. Set fonts, colors, stroke, shadow, background boxes, positions or nine-grid anchors, margins and fade/slide/pop animations. logo_file_id supplies the image for logo items. Keeps the soundtrack. It costs 1 credit a minute of video, charged only if the job succeeds. Free for the first 10 minutes, 10 times a day. Returns MP4 and the document JSON with download links, or job_id for get_job if it takes longer.

Example: "Use Audo to add the title “Episode 12” to the first five seconds of interview.mp4."

## Questions

**How do I put text on a video online?** Add your video above, pick a text preset, and press Add text to open the editor on Text. Type your words directly onto the canvas, drag the text box into place or pin it to one of nine anchor points, and press Export to download the MP4 with your text rendered on the picture.

**Can I add a logo or watermark a video?** Yes. In the editor, add a PNG, JPEG, or WebP logo layer. A PNG or WebP with a transparent background stays transparent on the video. Scale it down, adjust its opacity for a subtle corner watermark, and keep it visible for the entire clip or only during a specific section.

**Can text appear and disappear at exact times?** Yes. Every text line and logo layer has its own start and end bar on the timeline. Drag the bar edges, type exact timestamps, or snap to the playhead, and choose fade, slide, or pop entrance and exit animations.

**Which fonts, colors, and lower-third boxes can I use?** Choose from nine built-in display and sans-serif fonts—from Inter and Montserrat to Bebas Neue, Anton, and Bangers—with custom font weight, size, fill color, outline stroke, drop shadow, and a rounded background box for lower thirds and callouts.

**How is Add text to video different from Auto captions?** Add text to video places static or timed titles, headlines, lower thirds, and logo watermarks that you write yourself. If you want spoken words transcribed and highlighted automatically as someone talks, use Auto captions—or combine both in the same editor project before exporting.

**Is adding text to video free?** Audo adds text and logos to the first 10 minutes of a video for free, 10 times a day, with no watermark and no sign-up. A longer video costs $0.01 a minute ($0.60 an hour) for all of it, charged only if it works. No subscription. See pricing.
