Scrubbing on Timeline Does Not Work For Me

Hi, I am brand new to Shot cut. I have version 19.10. I have been trying to scrub across the timeline but it does not appear to work at all. I have tried using the “scrub while dragging” icon both on and off. All that happens is that I get nothing, no sound and no image change as I scrub. Only when I let go of the play head will the preview show me where I am.

What gives? What am I doing wrong ??

Many thanks !

Hi and welcome,

in the settings menu check ‘Scrub Audio’.
Maybe you scub too fast. You can also scrub pressing ‘shift’.
