  5. • Wordpad does at least two things to a binary

    file: – replaces byte 07 (ascii: BEEP) with a space – replaces every lonely 0A , 0B, or 0D (line feed, vertical tab, carriage return) with the bytes "0D 0A” • Rate of glitching is related to how dark the picture is, lost of low bytes -> lots of new pixels being introduced
  6. JPEG uses a lossy form of compression based on the

    discrete cosine transform (DCT). This mathematical operation converts each frame/field of the video source from the spatial (2D) domain into the frequency domain (aka transform domain.) - wikipedia.org/wiki/JPEG
