Supplied materials

  • Paper and a pencil, typed notes or a browser scratch area. Color names can replace colored supplies; drawn figures and timelines can replace performance.
  • Complete teaching inputs: An original silent storyboard has consecutive shots lasting 3, 5 and 2 seconds, with no overlap or gap. What is its complete planned duration? Supplied candidates: (A) 10 seconds (B) 11 seconds (C) 12 seconds (D) 9 seconds.
  • Independent check: An original silent storyboard has consecutive shot durations [3, 3, 2] seconds, with no overlaps or gaps. What is its total planned duration? Supplied candidates: (A) 10 seconds (B) 7 seconds (C) 8 seconds (D) 9 seconds.

Learn the idea

Plan a production that preserves meaning and honest records. Use redundant visual information, keep asset provenance and scope, calculate a consecutive edit timeline and interpret a supplied design-check record without inflating its findings. A consecutive nonoverlapping edit occupies the sum of its shot durations. Use the supplied no-gap, no-overlap condition before applying ordinary addition.

Reason through the supplied case: Add the three occupied intervals: 3+5+2=10 seconds. Their cumulative endpoints are 3, 8 and 10. The total checks the paper timeline under the no-overlap/no-gap model, rather than proving the duration of a rendered export.

Real overlapping transitions use a different timing model. This calculation checks an original storyboard plan and does not establish the length of an unrendered exported video.

  1. Read the complete teaching inputs and mark the feature, rule or constraint being tested.
  2. Compare the model decision with one rejected candidate; state the visible evidence or calculation that distinguishes them.
  3. Solve the independent check and the three changed-input practice cases before reading feedback.
  4. Make a three-shot silent storyboard lasting two, four and three seconds, with labeled cumulative endpoints.
  5. Check your artifact against these explicit criteria: The consecutive endpoints are two, six and nine seconds, and total duration is nine.

An original silent storyboard has consecutive shots lasting 3, 5 and 2 seconds, with no overlap or gap. What is its complete planned duration? Supplied candidates: (A) 10 seconds (B) 11 seconds (C) 12 seconds (D) 9 seconds. Model decision: 10 seconds. Add the three occupied intervals: 3+5+2=10 seconds. Their cumulative endpoints are 3, 8 and 10. The total checks the paper timeline under the no-overlap/no-gap model, rather than proving the duration of a rendered export.

Helpful tips
  • A consecutive nonoverlapping edit occupies the sum of its shot durations.
  • Real overlapping transitions use a different timing model.
An original silent storyboard has consecutive shot durations [3, 3, 2] seconds, with no overlaps or gaps. What is its total planned duration?

8 seconds

The shots occupy consecutive intervals, so add their durations: 3+3+2=8 seconds. Overlapping transitions would require a different timeline model; none are included here. The sum evaluates the plan, not a real video export.

Take it further

New-input analysis: An original silent storyboard has consecutive shots lasting 4, 2 and 5 seconds, with no overlap or gap. What is its complete planned duration? Supplied candidates: (A) 10 seconds (B) 11 seconds (C) 12 seconds (D) 13 seconds. Expected relationship: 11 seconds. The nonoverlapping shot intervals occupy 4+2+5=11 seconds in total. Their successive endpoints are 4, 6 and 11. This arithmetic checks the paper timeline; a rendered export remains a separate verification. Create your own artifact: Make a three-shot silent storyboard lasting two, four and three seconds, with labeled cumulative endpoints. Completion criteria: The consecutive endpoints are two, six and nine seconds, and total duration is nine.
