 Hi,

 Could you implement a new option for the 'fieldhint' filter - template (or
 pattern).
 This will be associated with the option 'mode' with the value 'relative'.

 For example we have a hint file (fh.txt) contained only 5 lines:
 0,0 -
 1,1 -t
 1,0 -
 1,0 -
 1,0 -b

 and filter:
 fieldhint=fh.txt:relative:template=1

 The option 'template = 1' will force the ffmpeg to use the hint file as
 some kind of template in a cycle not only for frames from 0 to 4, but also
 for the following groups of 5 frames until the end of the video.
 The default value is 0.

 I think it is a good idea.

 Thank you.
