Seek bar doesn't work well with video and animation By Tracy Hoang I imported a video to my Storyline and had a few items synced with the video. The seek bar of the player was also enabled. The problem was that when I scrubbed back and forth on the seek bar, the animations and video were out of sync. Items appeared at the wrong timings. Is there a way to work around this? I submitted my case for support, but thought maybe I should share this to see if there had been similar issues.
