Product
0 -> 1
Launched in 2021, this features was a much anticipated quality update.
How does it work?
When not triggered, the progress bar remains small.
Hold down the circle to scrub through the video. Video UI temporarily disappears to display duration.

Dragging the progress bar at the bottom of a video is a very basic functionality of any video player.
This feature is frequently used especially when the video is playing a part users are not interested in; it also meets the needs of users when they want to replay a part they missed or they want to watch again. In addition, when TikTok began introducing more longer form videos, this feature became vital for users.

Precision and Convenience in Viewing

The progress bar was a much needed feature, especially with TikTok rolling out and pushing more long form content to users.
Users need to have an appropriate scrollable area for their thumb so they don’t accidentally press the tappable areas surrounding such as the tab bar or music area.
Displaying the timestamp allows users to easily scroll to the point in the video they wish to view.
