Clips placed one after another on the timeline add up: clips of 41, 22 and 27 seconds make a 90-second video. One minute is 60 seconds, so 2 minutes 15 seconds = 120 + 15 = 135 seconds, and 225 seconds = 3 minutes 45 seconds. If a video must be 120 seconds and the clips add up to 95, you need 25 more seconds. Speeding a clip up to 2× halves its length; slowing it to half speed doubles it.
