I tried to use the Tiled Tiff transcoder but got weird
results: the output is only a small part of the
expected result, like as if it were only a 'tile'. I
didn't have the time to investigate further and I find
it safer to use the TIFFTranscoder even if I know that
the TileTranscoder would be more efficient in my case.

By the way, excuse me for answering late to your
question, I just didn't have a chance to read my mails
  during the last few days.
