Short-form video refers to brief video content, typically under 60 seconds, though some platforms extend this to 3 minutes, designed for quick and engaging consumption. Platforms like TikTok, Instagram Reels, and YouTube Shorts have popularized this format, emphasizing rapid cuts, trending audio, and concise storytelling. Short-form videos are highly effective for capturing attention, delivering quick messages, and driving viral trends due to their snackable nature and high shareability.
