Short description of YUVsoft Watermarking Demo 1.0.0.1: This is a demo of YUVsoft Watermarking technology (YUV Watermarking) capabilities. The program can watermark typical standard definition videos with a user defined text, making it possible to extract a mark after compression or other typical video processing. Also it can be used for hidden information transmission. In most situations a watermark can not be detected and/or changed by standard steganography methods.
