How to Add a Watermark to Multiple Videos

Place the same image or video watermark across a batch with consistent positioning, size, opacity, and timing.

The repetitive part

Branding, ownership marks, and campaign graphics often need to appear consistently across many deliverables. Rebuilding and aligning the same overlay for every video is repetitive and easy to vary accidentally.

When batch processing helps

Batch watermarking applies one image, GIF, or video overlay setup across selected videos, including timing and optional looping for animated media.

Ways to handle the job

Place watermarks on timelines

An editor provides detailed control, but each video still needs the same overlay imported, positioned, timed, and exported.

Overlay with scripts

Command-line filters can apply a watermark, but scaling coordinates, opacity, timing ranges, and mixed source sizes need explicit calculations.

Use BlinkClip visually

BlinkClip uses Overlay to preview the media and apply shared position, width, opacity, timing, and loop settings across the batch.

Step by step

  1. Select the videos

    Drag videos into BlinkClip or use Select Videos to choose the files that need the same change.

  2. Choose Overlay

    Select Overlay and choose the image, GIF, or video watermark.

  3. Set its appearance

    Choose horizontal and vertical position, width, opacity, timing, and whether animated media should loop.

  4. Review the batch

    Confirm the selected files, start processing, and wait for BlinkClip to finish the repeated job.

  5. Check the results

    Open the processed files in Finder and review representative outputs before replacing or sharing originals.

Useful checks

  • Test horizontal and vertical source videos.
  • Keep the watermark clear of important edge content.
  • Review opacity and timing on representative outputs.

Common questions

Can BlinkClip use a video as a watermark?

Yes. Overlay accepts images, GIFs, and video media.

Can a watermark appear for only part of the video?

Yes. Choose the whole video, a start-to-end range, the first seconds, or the last seconds.
