This contrasts with relying solely on coarse controls like “skip forward/backward” buttons.
-
Progress Indication
The scroll bar visually represents the current playback progress relative to the video’s total duration. The filled portion of the bar clearly indicates how much of the video has been watched, while the remaining portion reflects the unviewed content. This allows a user to quickly assess how far they are into the video and estimate the remaining viewing time. A quick glance can show if the video is almost over or barely started.
-
Buffering Display
Many implementations integrate buffering information into the scroll bar, visually indicating which segments of the video have been downloaded and are ready for immediate playback. This allows users to anticipate potential interruptions and adjust their viewing accordingly. If the scroll bar indicates a large, unbuffered section ahead, a user might pause playback to allow buffering to catch up.
-
Chapter Navigation
In videos with chapter markers, the scroll bar can serve as a visual table of contents, displaying demarcations for each chapter. Clicking on these markers allows users to jump directly to the beginning of the selected chapter, facilitating navigation within segmented content. For example, within a recorded lecture, one could swiftly navigate to the question-and-answer segment.
