Part 2: The most practical solutions to fix iMovie video rendering error 

In this section of our article, we explain how to fix the iMovie video rendering error. In fact, we explain several solutions so you can choose the best method that fits your situation. Also, you don’t have to try all these methods. Just try these solutions one by one and fix the issue.

01. Eliminate the corrupted frame to fix iMovie Video Rendering Error

As we explained before, the main cause of this error is a blackout or corrupted frames within the video. iMovie will not be able to render the videos as a result of those corrupted files. So, the first and most basic solution is to get rid of the corrupted frame. The corrupted or the blackout region of the video can happen due to the transitions you might have applied. So, let’s address that first. First, you should relocate the region that is turned into black. To do this, you should observe the whole video frame by frame until you see the black frame. In addition to that, you’ll be able to notice a flickering effect on the video when you preview it. You can try two solutions here; cut those frames out or replace them with new frames.

After trying those options, you should render the video once again to see if it works. However, you must not delete the respective rendered video once the rendering is done.

If this doesn’t fix the issue, you should move to the next step and see if it works.

02. Check if the respective video clip is deleted from your project to fix iMovie Video Rendering Error

For many users, the iMovie video rendering error appears when the video used in the project is deleted. So, you should check if the respective video is stored. If you, by any chance, have deleted that video once the rendering is done, that leads to errors. As a result, you will come across an iMovie video rendering error on your Mac. When you try to render the video, all the video clips used to create the file should be present. Those files are required to form the final output. On the other hand, rendering is just “drawing” your video using the present video clips. So, we strongly recommend you save the video clips where they were before rendering. Then, you should try rendering again.

Apart from that, the same issue can trigger if you change the location of the file. The program will recognize that the respective file is not present if you have moved it somewhere else. Eventually, it will lead to an iMovie video rendering error. In this case, you should just move the file back to its original location and try the rendering gain.

03. Check if the project comprises different file formats to fix iMovie Video Rendering Error

The next solution is to check if your project has different types of video file formats. If you have imported video clips from different sources, they may be of different formats. The only way to address this issue is by converting all those formats into one compatible format. After converting them into a single format, you should be able to render them once again. If the file format was the issue, that should be resolved at this stage. Be sure that you use a reliable tool to get the files converted into the format you prefer.
