Preview of Clip Won't advance as playhead is moved.

This is infuriating!! I am trying to move the playhead about a clip in order to select split points but the preview movie is not playing or advancing as I slide the playhead. The only way of getting an accurate split point is to keep clicking on parts of the clip and hoping it's close!

Why would this suddenly stop?

No other programs running.

A quit and re-start solves the problem for about 2 short splits, then the problem starts again.

Any help appreciated.

It could be a corrupt preference that is causing manual movement of the playhead to not advance the preview display. Try deleting preferences. It is a safe procedure that will not disrupt your projects of cause any loss of data. To delete preferences open iMovie while holding down the Option and Command keys and select to delete preferences in the box that appears. iMovie will open in a new library. Reopen your old library to get back to your projects. Now see if moving the playhead will advance the preview display.

Thanks. Did that and it worked well for about 5 minutes then froze on the timeline again - back to initial problem. Any other fix suggestion?

Closing down iMovie, then restarting solves for a short period, but the problem appears again after about a minute of editing.

Try redownloading iMovie. Drag the iMovie app from the Applications folder to the trash, but do not empty the trash. Then sign in to the app store, click on your name at the bottom of the app store side bar, and redownload iMovie from your displayed purchases. If not successful, drag your iMovie app out of the trash and place it back in the Applications folder.
