If you want to create a video ad that quickly grabs attention, what aspect should be prioritized?

To quickly grab attention in a video ad, prioritizing the first few seconds (typically the first 3-5 seconds) is critical. This means starting with a visually compelling scene, a captivating hook, or a clear and concise value proposition. Since many users scroll quickly through their feeds, the initial impression determines whether they will stop and watch the entire ad. For example, a food delivery service ad might start with a shot of delicious-looking food being delivered, paired with text highlighting a special offer, to immediately capture the viewer's attention.
