Video watermark typically affects video quality by adding a visual overlay or logo onto the video content. This overlay can slightly reduce the clarity and sharpness of the image, especially if it's placed in a prominent area or if it's particularly large or complex.
For example, if a watermarked video has a semi-transparent logo in the corner, the logo might slightly blur or distort the pixels underneath it, making that area of the video less clear. In some cases, if the watermark is too dark or too bright, it can also cause issues with the overall brightness and contrast balance of the video.
However, it's worth noting that modern watermarking techniques are designed to minimize these impacts, often using techniques like transparency adjustments, edge blending, and motion compensation to ensure the watermark blends smoothly with the video content.
When it comes to cloud-based video processing, services like Tencent Cloud offer advanced video watermarking features that can help minimize quality loss while still providing effective branding and copyright protection. These services often allow for customization of watermark transparency, size, position, and animation, enabling users to find the right balance between brand visibility and video quality.
