Final answer:
To add a watermark to a video on an iPhone, you can use a third-party app such as iMovie. Import your video, add a watermark image, position it, and then export the video with the watermark.
Step-by-step explanation:
To add a watermark to a video on an iPhone, you can use various video editing apps available on the App Store. While iOS does not have a built-in feature to watermark videos, third-party apps like iMovie, VideoMark, or Watermark Video Square provide this functionality.
For example, using iMovie, you can follow these steps:
- Open iMovie and create a new project.
- Import the video you want to watermark.
- Add your watermark image to the project.
- Resize and position the watermark on your video.
- Export the video with the watermark applied.
Some apps might require you to create the watermark separately before importing it into the video. Ensure the watermark is saved in a compatible format, such as PNG with a transparent background, for the best results.
Remember that watermarks should be subtle and non-intrusive, maintaining the video's viewability while protecting your content's ownership or branding.
