Video watermarking technology deals with video transcoding by embedding a watermark into the video during or after the transcoding process. This ensures that the watermark remains intact and visible in the transcoded video, even if the video format, resolution, or compression level changes.
For example, when a video is transcoded from a high-definition format to a lower-resolution format for streaming on mobile devices, the watermarking algorithm adjusts the watermark's size and position accordingly to maintain its visibility and integrity. This involves complex mathematical operations to ensure the watermark is not distorted or removed during the transcoding process.
In the context of cloud computing, video watermarking can be integrated with video transcoding services to automate the process. For instance, cloud-based video processing platforms like Tencent Cloud offer video transcoding services that can automatically embed watermarks into videos as they are transcoded. This ensures that all videos processed through the platform, regardless of their format or resolution, have the desired watermark, thereby protecting the content from unauthorized use and distribution.
