@rohith5429 I've created a PR to add this feature, please see #8287. A workaround is available here #8283 (comment)

@amtins, I made a build dist out of your respo amtins:feat/seek-bar-smooth-seeking and replaced it in my node_modules/videojs dist.
and added enableSmoothSeeking: true option to videojs in my angular application,
this.video = videojs(this.videoElement.nativeElement, {enableSmoothSeeking: true});
However, it's still jumpy. Could you please help?

@rohith5429 do you have this problem with any video, or just this one? Have you tried another video? To make sure it's not a media-related problem.

What does player.seekable() return?

[rohith5429]

I received TimeRanges { length: 1 } from video.seekable(). I also tried other videos, but encountered the same result.

When I tested the same video with the HTML5 video player, the seek bar was very smooth. However, all of my code logics and features are written based on video.js, so switching back to the HTML5 video player is not an option.

I would appreciate it if the video progress bar could exhibit a smoother behavior, ideally following the mouse movements seamlessly. Thank you for your consideration.

I think its not a video.js bug. Its about video encoding settings. You can re-encode videos with "lower key frame distance/interval" (like 6, usually default is: 72) you would get smooth seeking. You can do it by ffmpeg or in premier pro render settings.
