Your video contains a complicated demonstration, and you want to know what viewers said during that section. Danmaku can provide contextual reactions, but it is not a second-by-second retention curve or a record of silent viewers' opinions.

Match the time range to the video version

The capability takes the work identifier, total duration, and start and end times. Confirm the actual version and duration before using the documented values. The same demonstration may occur at different positions in a shortened edit. Keep the inspected interval so colleagues can revisit it.

Read reactions alongside the footage

Inspect the returned timing information and text before aligning comments with the video. Surprise, laughter, or confusion may concern different elements of the scene. Repeated phrases can be shared jokes rather than independent reports, and should not automatically become satisfaction scores.

Propose a specific editing hypothesis

If the observed expressions suggest an unclear step, consider a close-up or a pause for explanation. Label that as a proposed change rather than a proven causal solution. Few comments do not establish low viewing, and many comments do not establish understanding. Deliver the segment reference, observed reactions, possible explanations, and evidence still needed. Evaluate later results through appropriate additional measures.
