What is Interactive Video?
Interactive video adds controls or timed elements that let viewers choose paths, select objects, navigate branches, or trigger actions during playback. Those inputs can alter the content, sequence, or application state.
How Interactive Video works
An interactive presentation usually separates the encoded audio-video essence from a timed model of hotspots, questions, and navigation rules. A player listens for media-time cues, renders an accessible overlay, and maps viewer input to seeks, alternate assets, or application events. Authoring therefore spans editorial branching, UI state, and media packaging rather than codec work alone. Delivery pipelines also need a noninteractive rendition or deterministic default path for clients that lack the runtime.
Key facts
- HTML media elements expose playback and timed-track primitives, but they do not define a portable branching graph; application code or a player SDK supplies that behavior.
- Clickable regions should be stored in normalized media coordinates and transformed with the displayed video, or letterboxing and responsive resizing will misalign targets.
- Branch analytics need stable node, choice, and playback-session identifiers; a simple completion event cannot distinguish abandonment from a deliberate early branch.
When Interactive Video matters
Teams use interactive video for branching training, product exploration, advertising, education, or entertainment. They must define fallback behavior for players that cannot execute the interactive layer.
