Fun Fact
Social media videos under 15 seconds consistently achieve the highest engagement rates across platforms. This insight drove TikTok's original format decision when it launched - videos were limited to exactly 15 seconds to maximize viewer retention and completion rates. Instagram Reels and YouTube Shorts later adopted similar short-form formats. Marketing research shows that shorter videos tend to be watched completely more often, which signals to algorithms that the content is engaging, resulting in broader distribution and reach.
