Reasons for video rendering error 10008

There are numerous reasons why the iMovie rendering error 10008 error occurs. Let’s take a look at some of the most common ones:

1. Attempt to merge video clips of different formats

Often, to create a slightly long video, you might need to merge a lot of short videos captured at different times. In such a case, if a few of the short videos are in a file format that’s different from the other short videos, the merged file can become corrupted and cause iMovie to throw this error. For example, if all the other short video files are in the MP4 format but 2-3 of them are in MKV format, an attempt to export the final merged file will cause this error.

2. Incomplete import or change in the disk path of video clips

Before you can edit a file with iMovie, you need to import it within the software’s interface first. Now if the import operation doesn’t complete successfully, the resultant edited file can throw iMovie video rendering error 10008. This error can also be encountered if after importing the video into the software, you change the original file’s location or delete it from its original location.

3. Corruption of the file(s) used in the project

If the original video files used for editing are corrupted, iMovie will fail to render them and throw this error.

4. Lack of storage space

If you do not have sufficient disk space to save the exported video file, then too iMovie may throw this error.

How to fix iMovie error 10008?

There are a lot of simple fixes that you can try out to fix this video rendering error. Let’s go through each one:

Update your iMovie application and restart it to check if it solves the issue. Running an older version of the application might cause runtime errors in it which can result in random errors such as this.

Note: Before you do this, don’t forget to save your video project!

  • Check if all the used video clips are of the same format. Even if one of them is different, it can lead to this video rendering error.
  • Check your drives to ensure that they have enough storage space to export the video file. If not, choose a directory (partition) of the drive with enough space to store the video file, or alternatively free up some space and then trying again.
  • Don’t delete or relocate the video files that you have imported into the iMovie project as the software will consider such files as corrupted and stop the rendering process.
  • Identify the corrupted files among the videos you’ve imported into iMovie and eliminate or replace them. You can find damaged files easily by first disabling all the tracks in the video, and then enabling each track one by one. As you enable tracks, try to render them too. If any track fails to render, you should know that the video file in that track is corrupted and must be repaired. Once you’ve spotted the corrupted files, you can fix them and then merge them back to your original video file.

While the other fixes mentioned above are relatively simple, in the last case, after you’ve identified corrupted video files you might not be able to discard such files since they may contain important coverage or clippings. In such a scenario, repairing them might be the only solution to complete your video.
