We wanted to quantify such claims. So we took to YouTube and counted the number of cuts in 154 trailers over the decades—a sample of Oscar winners, top grossers, and personal favorites. Because lengths vary (the ad for 1952’sThe Greatest Show on Earth clocks in at 6 minutes, 53 seconds!), we compared the rate of cuts per minute.
Through the ’50s, the average rate was 12 cuts per minute. Since the ’90s? Thirty-eight.
It would seem like holding a shot longer than 3 seconds in today's movie trailer market is anathema, not to mention releasing a trailer that is nearly 7 minutes long...!
