A conversion specifier is a code that starts by % (except newline which is \n). The conversion specifiers
used has the same function as for the C function strftime (3). The most commonly used are:
- %Y = year
- %m = month as two digits
- %d = date
- %H = hour
- %M = minute
- %S = second
- %T = HH:MM:SS
These are unique to motion
- %v = event
- %q = frame number
- %t = thread (camera) number
- %D = changed pixels
- %N = noise level
- %i = width of motion area
- %J = height of motion area
- %K = X coordinate of motion center
- %L = Y coordinate of motion center
- %C = value defined by text_event
With a combination of text, spaces, new lines \n and conversion specifiers you have some very flexible text features.

for Advanced Filename and Text Feature.
