moov
MOV   QuickTime movie file

.MOV files have a complicated file signature. The string "moov" is the most common but I have also seen:
  0x66-72-65-65   free
  0x6D-64-61-74   mdat
  0x77-69-64-65   wide

And the following have been reported to me:
  0x70-6E-6F-74   pnot
  0x73-6B-69-70   skip

Furthermore, if you look at byte position xxxxxxxx+4 (where xxxxxxxx is bytes 0-3 of the header), you
will find one (or more!) of these strings repeated; the string "free" seems to be the most common. For
more information, see the QuickTime File Format page. (Thanks to D. Wright for getting me started on this!)

NOTES on JPEG file headers: The proper JPEG header is the two-byte sequence, 0xFF-D8, aka Start of Image (SOI) marker.
JPEG files end with the two-byte sequence, 0xFF-D9, aka End of Image (EOI) marker.

Between the SOI and EOI, JPEG files are composed of segments. Segments start with a two-byte Segment Tag followed by a
two-byte Segment Length field and then a zero-terminated string identifier (i.e., a character string followed by a 0x00), as
shown below with the JFIF, Exif, and SPIFF segments.

Segment Tags of the form 0x-FF-Ex (where x = 0..F) are referred to as APP0-APP15, and contain application-specific information. The
most commonly seen APP segments at the beginning of a JPEG file are APP0 and APP1 although others are also seen. Some additional
tags are shown below:
