How long should the EI video typically be?

• A. Approximately 1 minute.
• B. Approximately 3 minutes, with a fast pace.
• C. Approximately 2 minutes, ensuring content is tight, cohesive, and impactful.
• D. Approximately 5 minutes or longer.

Answer: (C)

Balancing depth of storytelling with viewer attention span is what this is aiming for. About two minutes gives enough time to set up the challenge, outline your engineering approach, show a concise demonstration of the result, and clearly describe the impact. That length keeps the narrative tight and cohesive, helping viewers understand what you built, why it matters, and how your team collaborated, without unnecessary filler. A shorter video tends to skim over important context or impact, making the project feel less complete. A longer video risks losing viewer engagement and dilutes the message, even if the pace is fast. Two minutes is the reliable target that keeps the story focused, cohesive, and impactful.
