Part 2: Top 12 iMovie Problems and Solutions

Here we collect the top 12 most common problems reported by iMovie users. Check to see if you have any of these problems.

1. iMovie Export Failed

There are many factors that may cause export failure. Like lack of computer space, corrupted project, or wrong export file name.

Check if the storage space is available on your Mac device to assure enough space for movie exporting.

If this is not the cause, check if there is something wrong with your projects. Skim slowly through the project, looking for any anomalies such as flashes or other glitches, and replace the corrupted clip.

What's more, special characters are not permitted in the project name, so check out if there is a "hyphen" or any other "wild card" character in it.

2. iMovie Error -50

The iMovie error 50 is mostly caused by damages to the Windows system files. It's a video rendering fault. And sometimes, it could be other reasons, such as the app remains open for a long time.


Uninstall the app. And then download its latest version and install it as an administrator.

3. Slow Speed

The speed of iMovie may slow down when too many commands are given at one time. The slow functioning can also be a result of inadequate memory.


  1. You should give one command at a time and systematically so that iMovie can’t be overworked.
  2. It would be better if you delete all the idle files or files that are not required in your project, as it will make sufficient storage space and improve the functioning of iMovie.

4. Distorted Files

If the right importing and exporting procedures are not followed, then audio or video files may get distorted, hence resulting in blurred images.


This problem can be solved if you import or export files of the right size. The editing should be performed in the timeline only.

5. Improper Working of Trailers

The trailer is the first thing that attracts the audience for watching a movie, but if it does not work properly, then it causes huge inconvenience.


Step1. You can open the “Fonts” app to activate all the fonts. Now create a new account and login into that new account.

Step2. On doing it, the iMovie will restart on its own. From there, go to the “disk utility” button, choose “repair permission” and then “restart OSX”.


6. Poor Camera Connection

If you import your footage directly from the camera, then you may get a “There is no connected camera” message in the interface of your iMovie. The incompatibility of the USB cable on either camera or the iMovie can be another reason behind the poor connectivity.

You can replace the USB cable with FireWire for solving this issue. If you are facing this problem while utilizing a camcorder, then you can follow the guidelines given out in the user manual.

7. Video Effects Rendering Failed

The video effects greatly enhance video quality, but some effects become troublesome when they fail and difficult to render successfully.


It is advisable to go through the guidelines given for each and every effect that you wish to include in your video.

9. Lacks Sound

Sometimes wrong preferences can lead to the absence of sound in the movie. The incompatible format can be another reason behind this problem.


You should adjust the settings properly. There will be a good quality of sound if you use only those formats that are supported by iMovie.

10. Disappointing Bend Results

This is a common issue that people deal with at the close of the project. It can be incompatible movies, poor quality video, and audio, or an unfurnished project.


You can solve this issue by following all the outlined procedures from beginning to last without omission.

11. Error Generating DVDs

Some people find difficulty in converting longer movies from iMovie to DVD. It may be due to an unsupported Mac system or low RAM.


Make sure the software’s temp file folder has enough space to store the data. Or try to update your DVD driver.

12. iMovie Error Code 10008

The iMovie 10008 error code is often caused by corrupted or black frames in the video project or different video formats in the project.


  1. Preview the video frame by frame and delete the corrupted black frame.
  2. Convert the videos to the same supported formats and try to render the project again.
