Add Watermark to Video

Protect your content with a logo or text watermark and control placement and transparency.

or click to browse

Maximum file size: 500MB

2. Configure Overlay

Add text or image overlay to your video

Choose either an image or text overlay (not both)

Position and appearance

Intro

Watermarking helps protect content and reinforce branding. With VideoComposer, you can overlay a logo image or a text watermark on a video and control the placement and opacity. The output is a clean MP4 ready for distribution.

The overlay tool supports either an image or text at a time. Set x and y coordinates to position the watermark and adjust opacity to keep the content readable. This workflow is designed for fast and repeatable branding across clips.

If you need to watermark many files, the API makes it easy to automate. Submit jobs programmatically and retrieve outputs when they finish without manual uploads.

Watermarks are also useful for ownership and compliance when sharing pre-release content. A consistent logo in the corner makes it clear where the video came from without blocking the main action.

The overlay tool re-encodes the video to apply the watermark. Use a high-resolution logo and test placement on a short clip before processing a large batch.

How it works

  1. Upload a video or paste a direct URL.
  2. Choose an image URL or enter watermark text and set position.
  3. Submit the job and download the watermarked MP4.

Use cases

  • Add a logo watermark for brand consistency.
  • Apply text labels for compliance or ownership.
  • Prepare videos for social sharing with attribution.
  • Protect content distributed to external partners.
  • Mark review drafts before public release.

Formats and limits

  • Inputs: MP4 and WebM in the browser tool.
  • Output: MP4.
  • Overlay supports image OR text (not both at the same time).
  • Opacity and position are configurable; processing time depends on duration.
  • Outputs are re-encoded to apply the overlay.

After processing

When your add watermark to video job completes, you will receive a downloadable output URL. You can save the result locally, share it with a teammate, or feed it into another tool such as the trimmer or converter. For repeatable workflows, use the API to store outputs in your own system and automate the next step.

Tips

  • Use semi-transparent watermarks to keep content readable.
  • Place watermarks in a corner to avoid blocking key UI.
  • Keep text short and legible at common resolutions.
  • Use consistent positioning across a series of videos.
  • Automate watermarking for batches with the API.
  • Test opacity and placement on a short clip before processing large files.
  • Choose a high-contrast logo so it stays visible on bright scenes.
  • Leave 5-10% padding from edges to avoid cropping.

Deep dive

Transparent PNG logos usually produce the cleanest overlays. JPEG logos can introduce boxes or backgrounds that distract from the content.

Text watermarks should be short and high-contrast. Test on a short clip to ensure readability across different video scenes.

Consider where the watermark sits across different aspect ratios. Keeping it inside safe margins helps avoid clipping on various players.

Different players can crop or letterbox video. Preview a short clip to confirm the watermark stays visible across common resolutions and aspect ratios.

If you need the watermark to appear only for part of a video, you can split the clip into segments, apply overlays to the segments that need branding, and merge the results into one file.

Workflow checklist

  • Use a transparent PNG logo for clean overlays.
  • Test placement and opacity on a short clip.
  • Keep watermark text short and readable.
  • Automate batches with the API when you have many files.
  • Store watermark settings so branding stays consistent.
  • Keep the watermark inside safe margins to avoid cropping.

FAQ

Can I add a logo watermark?

Yes. Provide a direct URL to an image and set the position and opacity.

Can I add a text watermark?

Yes. Enter the text, choose a font size, and set position and opacity.

Can I change watermark opacity and position?

Yes. You can set x and y coordinates and adjust opacity from 0.0 to 1.0.

Will watermarking affect video quality?

Watermarking re-encodes the output to apply the overlay. Quality remains high for typical settings.

Can I watermark multiple videos at once?

The browser tool processes one video per job. Use the API to automate multiple watermark jobs.

Is there a watermark on the output from your tool?

No. VideoComposer does not add any extra watermark beyond what you specify.

Can I automate watermarking via API?

Yes. The API supports the same overlay parameters for automated workflows.

Automate watermarking with the API

Use the overlay endpoint to apply logos or text programmatically. This is ideal for content pipelines, user-generated content moderation, or branded exports.

Submit jobs with image or text parameters and retrieve output URLs when processing completes.

Apply a consistent watermark across multiple videos by reusing the same overlay settings in your API requests.

  • POST /video/overlay with overlay_url or text
  • Set x, y, opacity, and font_size as needed
  • Track completion via /jobs/:id
