Then video frames follow, each starting with 16-bit size.<br />
<br />
Frames are split into 2x2 tiles and use the following opcodes to decode them:<br />
* 0-63 -- this is the first pixel value, other three pixel value follow<br />
* 64-127 -- fill tile with the value of low 6 bits of the opcode<br />
* 128-255 -- skip 0-127 tiles<br />
<br />
Video uses 64 greyscale shades with 0 corresponding to white and 63 corresponding to black.<br />
