How to Fix iMovie Video Rendering Error 50 in 8 Ways

1. Update and Restart iMovie

Restarting iMovie is the most frequent solution. You can update iMovie and then restart the program if it isn't running the most recent version. Additionally, you can experiment with altering the export format, resolution, bit rate, file name, and other settings.

2. Uninstall and Reinstall iMovie

If restarting iMovie does not solve your problem, you might try entirely uninstalling iMovie and then reinstalling it. This could repair some damaged iMovie package files.

3. Detaching Audio from Video

The problem may also exist in your audio from the original video. You can try to detach audio from video and then share video from iMovie. If the extracted audio is important to your video, you can try to add audio to video after exporting video from iMovie.

4. Changing to Different Fonts

The project could be corrupted if you receive a rendering error 50. A title, a subtitle, or a font could all be damaged. Altering the font in your title might be worth a shot. Open the Font Book application to examine your fonts, and then delete any that are damaged. If the problem persists, try starting iMovie while pressing the Option and Command keys simultaneously, then choose to erase preferences from the pop-up menu that displays. That can fix problems occasionally.

5. Move your Media into a New Project

If the project you exported still failed to render, you can also try moving your media into a newly-created project, sharing out from there, and seeing if that resolves the issue.

6. Check the Space on your Destination Drive

There's a chance the video you exported won't fit on your destination drive's available space. Verify if the area can fit your video by inspecting it.

7. Frame by Frame Examination

The error notice informs you that a frame or video clip in your project has some corruption. If all other options fail, you can perform a frame-by-frame scroll of your project.

Expand your timeline using the duplicate, and then slowly browse over it to search for artifacts, black frames, white flashes, and any other indications of corruption.
