Video Editing Worksheet: Video Length

Animation and design lesson 21: Video length sums · Set 176 · 40 questions

Creator's tip (Add the clips): Video length = the clips added up. Minutes → seconds: × 60, then add the extra seconds. Seconds → minutes: take away 60 as many times as it fits. Still needed = target − what you have; 2× speed halves the time, half speed doubles it.
