These filters are designed for storing and transmitting video sequences with alpha using higher-efficiency codecs such as x264 which don't natively support an alpha channel. 'alphaextract' takes an input stream with an alpha channel and returns a video containing just the alpha component as a grayscale value; 'alphamerge' takes an RGB or YUV stream and adds an alpha channel recovered from a second grayscale stream.
