A mere four days after giving a "lecture" in Concordia, I had to give another presentation at Université de Montréal, on the current market situation in subtitling. This time was different since the material was intended for B.A. level students, and I was focusing one one aspect of the audiovisual industry. I showed some clips that were done in 1997, 1999, 2002 and 2003, so that they saw how the whole thing evolved.
I also kept my presentation short and sweet : 10 slides is the maximum...
It works every time.
