Try these troubleshooting steps in order
After trying each step below, test iMovie again to see if you've fixed your issue.
Restart your Mac
Reset NVRAM
If you use an external device with iMovie like a camera, reset NVRAM:
- Shut down your Mac.
- Disconnect all external devices other than your keyboard and your mouse.
- Reset NVRAM.
- Open iMovie and attempt to reproduce your issue.
- If iMovie works, reconnect devices one at a time until you can reproduce your issue. Restart your Mac after reconnecting a device if the device requires it.
- If iMovie still doesn't work, you might need to update your device's firmware or have the device serviced.
Update macOS and iMovie
Choose Apple menu > App Store, then click Updates. If an iMovie update is available, click Update to download and install it.
Check camera and media format compatibility
Make sure you're using a camera and media format that works with iMovie. If you can't find your camera listed or need further assistance, contact the manufacturer of the device for support.
If you're using a third-party video interface with your Mac, check with the manufacturer for firmware or other software updates for your device.
Test with a new library and project
You can create a new library and test project to check if the issue is with your library, project, or iMovie app. First, create a new library:
- Quit iMovie.
- While you press and hold the Option key, click the iMovie app in the Dock or double-click the iMovie app in the Applications folder.
- In the Open Library window, click New to create a new library.
- Name the test library 'Test iMovie Library,' then save it to the Desktop.
Next, create the test project using a built-in trailer template, then export it as a QuickTime video file:
- In iMovie, click Projects to return to the Projects view.
- Choose File > New Trailer, click the Action trailer template, then click Create.
- Choose File > Share > File, click Next, name the file 'Finish Line,' then save the video file to the Desktop.
Next, import the QuickTime video file into a new project in the new library:
- Click projects to return to the Projects view. In the window, click OK.
- Choose File > New Movie.
- Choose File > Import Media, then click Desktop in the Import window sidebar. Select the 'Finish Line.mov' file in the list, then click the Import Selected button.
- Select the clip in the browser, then press the E key to add the clip to the timeline.
- Try to recreate the issue you were having. For example, if iMovie quit when adding a transition, try to add a transition to the timeline.
If the new library and project work as expected, you've isolated the cause of your issue to the original library or project. Try to restore a previous version of the original library from a Time Machine or other backup.
Test iMovie with a new user account
Create another user account on your Mac, then test iMovie with the new user account.
Reset iMovie
Reset iMovie to default settings. Libraries won't be affected.

— A User from Yahoo Answers
Macs like all computers, Windows or Vista, can run slower over time. By performing a few simple clean up and maintenance tricks, you can have your slow Mac back running like new in no time. Here in this iMobie guide is by no means a comprehensive list of things that could be slowing down your Mac and how to fix it to speed up your Mac.

Reason 1: Mac hard drive is nearly full
First of all, go to check and see if you have enough free hard drive space to work with: Click the Apple menu > Select 'About This Mac' > Click on the 'More Info' button > Choose the 'Storage' tab to check the disk storage overview and capacity.
Like every Mac user, you might have stored many huge video files, thousands of photos and music tracks on your Mac computer. The popularity of using solid-state drives (SSDs) of Mac computers means considerably less capacity than traditional hard drives. Even an iPhoto library can quickly fill up a MacBook Air's 64GB or 128GB SSD, and nothing slows a Mac than having too much on a hard drive.
Solutions:
Firstly, find the large media files on your Mac, delete the unused videos, apps, photos, etc. Or you can move all of them to an external hard drive, and remove them from your Mac.
Secondly, remember empty your trash cans, say the user account's main trash can and the iPhoto/iMovie/Mail trash can.
Thirdly, remove the junk files generated from your web browser, system, or applications. A quick and effective way is using a smart Mac cleaning software, MacClean.
- It removes junk files from Safari, Chrome, Firefox and Opera all in one place, covering caches, cookies, browsing history, download history and sessions.
- It Clears user junk, system junk, development junk, and app leftover.
- It works for all Macs, including MacBook Pro/Air, iMac, Mac mini, Mac Pro, etc. Download MacClean now to free up more space.

Reason 2: Don't have enough RAM
A question from a Mac user: 'I have a 27' iMac (Late 2012, OS X 10.9.2) with 8GB RAM. The usage of memory is always above 7GB, even though I don't think I am running that much stuff. This leads to the occasional hanging of a program and occasional feeling of the computer being lagged.'
Yes, most Macs ship with between 4GB and 16GB of RAM. If your Mac has only 4GB or 8GB RAM, the system might be running low when launching programs or loading documents.
You can check your RAM by using the Activity Monitor application (under Utilities in the Application folder). Click on System Memory tab and have a look at the pie chart at the bottom. If the chart is largely red or orange which means you are running out of RAM.
Solution:
Step 1. Open up Terminal: ~/Applications/Utilities.
Step 2. Enter the command: Purge, and tap the enter tab.
Step 3. Give your Mac a minute or two to complete the process.
Open up Activity Monitor to see the before and after results, you'll find the Free size increases in System Memory.
