The main function of a video watermark is to protect the copyright and ownership of the video content by embedding a visible or invisible mark that identifies the source or owner of the video. This helps in preventing unauthorized use, distribution, or modification of the content.
For example, a news channel might add its logo or station name as a watermark at the bottom right corner of its video footage to assert its ownership. Similarly, a content creator might use a watermark to prevent others from stealing and reusing their videos without permission.
In the context of cloud services, platforms like Tencent Cloud offer video processing capabilities that include the addition of watermarks to videos. This can be done through their Video Processing Service (VPS), which provides various tools for video editing, including the ability to add customizable watermarks to videos stored in the cloud.
