  • Part 2: Top 15 iMovie Problems and Solutions

    Here we collect the top 15 most common problems reported by iMovie users. Check to see if you have any of these problems.

    1.iMovie Failed to Export

    Many factors may lead to this iMovie error. It might be out of memory, file conflicts, corrupted project and improper export setting.


    Check the storage space to see if it's available on your Mac to ensure enough space for exporting.

    If that is not the cause, check if something is wrong with your projects. Be it special characters in your file name or any anomalies glitches, you need to replace them with the correct ones.

    2.Poor Camera Connection

    It's possible to encounter a poor camera connection problem when directly using iMovie to capture footage from the camera. This error could result from various factors, including incompatibility of the USB cable on either iMovie or camera.


    To fix this error, you can replace the USB cable with another output option like FireWire. If you're facing this problem when using a camcorder, there's nothing better than following the guidelines in the user manual.

    3.Slow Speed

    The slow speed problem is more likely to drive people crazy. This error could be a result of too many commands given out at the same time, insufficient memory or poor computer performance.


    You'd better give one command at a time to ensure that iMovie is well-rested.

    You can also delete all the files that are not required in the project so that it will leave enough storage space and improve computer performance.

    4.iMovie Crashing

    This annoying problem usually occurs when your computer is overworked or runs with a corrupted file.


    This error can be solved by conducting the proper workload of your project. By the way, the file usually corrupts due to viruses so remember to scan your systems regularly to avoid virus invasion.

    5.Distorted Files

    No matter what types of resources you add to iMovie, file distortion may happen if the right exporting and importing procedures are not followed, hence generating choppy and blurred images.


    To fix this problem, you need to import or export files of the right size so that iMovie can process them without damaging any original quality. Additionally, all the editing steps should be performed in the timeline only.

    6.Lack of Sound

    Many factors could lead to this problem. You will get a voiceless video if you forget to add the sound that especially happens during recording. Besides, wrong preferences and incompatible formats can also be the reason for the absence of sound in iMovie.


    Firstly, record the sound with a third-party extension like Soundflower to re-record audio if you forget to capture audio. While for incompatible format issues, format conversion may help you settle this problem.

    7.Sound out of Sync

    Many people complain about iMovie exporting sound out of sync. Combining media from different cameras and audio with different rates plus different video formats can cause this problem.


    To get rid of this video problem, you need to check all the segments in uniformity, including codecs, formats and frame rates, as much as possible.

    8.Error Creating DVDs

    Many people report difficulty converting videos from iMovie into their DVDs, especially for some long-hour movies. This source of the problem may relate to an incompatible Mac system or low RAM.


    Try to improve its RAM or change your system to a friendly one. Remember to check the software's temp file folder has enough space to store the data.

    9.Error Video Effect Rendering

    Most people apply video effects to enhance video quality but some of the effects will become annoying when they fail to render smoothly.


    It's wise to follow the guidelines for each and every effect when you want to apply it to your video.

    10.Annoying Blend Results

    This is one of the common problems for many iMovie users. It can be poor-quality audio or video, an unfinished project or incompatible videos.


    To solve this problem, you need to follow all the outlined procedures from beginning to end without any omissions.

    11.iMovie Error Code 10008

    The famous iMovie 10008 error is often caused by file corruption, merging different video formats or deleting videos from the system.


    1.Check the final edited video frame-by-frame to detect and delete the corrupted black frame.

    2.Be sure all the mini-clips and videos have the same format and try to render the project again.

    12.Wrong with the Trailer

    The ineffective trailer could be the worst problem you will experience with iMovie. This may happen even when selecting the best video and audio clips but ending up with disappointing results.


    1.Go to Fonts to activate all the fonts, then create a new account, log in and iMovie will automatically start.

    2.By doing so, go to the “disk utility” button, choose “repair permission” and then “restart OSX”.

    13.iMovie Error 50

    Some iMovie users have encountered a notification that reads "iMovie Error 50." This issue is often used by damage to the system files as a corrupted file can affect the normal functioning of iMovie. But sometimes, it could result in opening this app for a long time.


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

    14.iMovie Error 10004

    This message that reads video render frame failed:10004" may appear on your iMovie screen when you try to export the edited project. This error implies that there is a problem with one or more clips in your project.


    The first thing you can try is to skim slowly through the project looking for any anomalies such as flashes or other glitches, and after that replace the clip that has the issue.

    Another option to test if you mistakenly use a corrupted file. To check this, copy this video in your timeline and paste it into a new project just in case the project is corrupted.

    15.iMovie Error 260

    Many people encounter this instruction during their exporting process and this is a common iMovie problem for iOS errors.


    1.Duplicate your iMovie project, remove one thing at a time, and export to find the bad files. Remember to check the audio files.

    2.Remove slow-mo or time-lapse video if there is and update your iOS and iMovie to the latest version.
