I could be misreading this, but as far as I can tell, there are more video and film editors today (29,240) than there were film editors in 1997 (9,320). Seems like an example of improved productivity shifting the skills required but ultimately driving greater demand for the profession as a whole. Salaries don't seem to have been hurt either, median wage was $35,214 in '97 and $66,600 today, right in line with inflation.
