B. Tags relating to recording offset
StripOffsets
For each strip, the byte offset of that strip. It is recommended that this be selected so the number of strip bytes
does not exceed 64 Kbytes. With JPEG compressed data this designation is not needed and is omitted. See also
RowsPerStrip and StripByteCounts.
