If you work with iMovie much at all , you ’re in all probability familiar with the keyboard shortcuts for cursorily skip over through your labor — budge and the Left or ripe arrow keys will move the cursor on your timeline backwards or forwards , 10 frames at a time . These are very utilitarian shortcut for sail large projects — quick enough that you do n’t pass all daytime moving about , yet slow enough that you may still get a signified for what portion of the project you ’re currently take in .

The only downside of this method acting is that you do n’t see live video ( or hear any audio ) . or else , the timeline marker plainly moves in 10 - chassis increments , and then displays the frame at the Modern placement . But what if you desire to watch some ( or all ) of your projection , unadulterated with sound recording … but do so in less time than would otherwise be want ? In other words , you ’d like to see a spry “ validation see ” that record all title , effects , audio , and video footage , but in less time than take to make for the task at normal amphetamine . Well , thanks to a duad of undocumented iMovie keyboard crosscut , you’re able to do just that .

Position the timeline marking where you ’d like to pop out viewing your project , then urge on the ‘ ] ’ key . Playback will start , although the timeline marker will not move . You ’ll hear sped - up audio as your video plays back at roughly twice normal speed . For even more fun , try the ‘ [ ’ key alternatively . Now your project will meet rearwards , also at twice normal fastness — consummate with audio , though you ’ll be firmly pressed to read it ( unless your project admit somespecial tracks ) .

To stop the high - speed playback , you’re able to either compact the same activation key again , or just compress the space saloon . Because the timeline indicator does n’t move in this playback style , it ’s not useful at all for navigating your project . But it can definitely preserve you some meter in the review stage .
