Resource Overview

Watermark addition conceptually treats the video file as one "layer" and the custom watermark as another layer, with both layers superimposed to achieve the embedding effect. This process typically involves matrix-based pixel manipulation and alpha blending for transparent overlays.

Detailed Documentation

When adding watermarks, we conceptually treat the video file as one layer and our custom watermark design as another layer. By superimposing these two layers through pixel-level operations, we achieve the watermark embedding objective. From a technical implementation perspective, this involves reading video frames into image matrices, performing coordinate-based pixel value calculations, and applying alpha channel blending for transparent watermark effects. Additionally, watermark integration serves functions like copyright protection and brand promotion. Consequently, watermark implementation not only safeguards the original video content's rights but also enhances the video's commercial value and recognizability through embedded metadata or visual markers.
