imovie not exporting video to file (error 10004)

No export options work after update. Only works if you have a single clip. Fails every time it tries to switch from one clip to another. Had to use quicktime for now to export the movie.

I'm having the exact same problem now after updating iMovie and upgrading to High Sierra 😒 Clips that worked well before and I had no problem exporting now encounter this problem. Some look damaged as seen on the image below:

When I remove this part, it exports fine. But this still wasn't a problem before the update and it's frustrating to lose that part of the clip.

I am having a similar issue. The only thing that has changed in my process for editing is that iMovie was just updated to the newest version so I am convinced it is a bug with the new iMovie and not an actual file/clip issue. I am very frustrated because I've spent 6 months on this project and JUST NEED TO EXPORT IT to finalize things. SOMEONE FROM APPLE PLEASE HELP.

Things I've tried:

- MANUAL frame-by-frame check on all new edits

- New clips individual share attempt (they worked so they are not corrupt files)

- Share 1st half (failed), share 2nd half (failed)

- Apple Support, Facebook plea, Reddit plea

- Remove all transitions

Can someone from Apple please prioritize this? The support line is closed tonight so I will try again tomorrow.

I've performed a clean install of High Sierra. This evening (Italian time) I will try to export a video that gave me problems to check if this issue is related to the upgrade from Sierra to High Sierra, or if it is related to the App itself...

Sorry......2nd Error later ,Same error:

If you show the correct rendered Part of your Video, at the End you can See where The Render Process is broken.

I have the same issue since the update - I can't even export movies I have previously exported - no matter what I do with settings, edits or duration it will not export my files - used to work fine before the update. Help - I use this for work, can't get anything done.

Same for me. Used old videos that worked fine before the update and now I can't do anything. Get this every time no matter what I do:

Video rendering error: 10004 (iMovie error 10004: renderVideoFrame failed)

Same issue here. One video clip, accompanied by an mp3. the audio is placed in there 3 times with a small overlap. Exports about 10 seconds. Doesn't correlate with any transition what so ever. Those are further down the road. #iNomovie

so what did you do with the ppt? I have a small project containing some video clips with moving text and images... exported from Powerpoint. Does it mean I can not use Videofiles from PowerPoint?

Thanks?

Sorry but no solution. I filmed a musical and need to put all pieces together , cannot take 4 sec off and still have the sound sync. Severe problem I need to have this finished soon.

Next attempt is to go back to 10.0.7 which worked last week.... knock on wood

This removing of the first couple of nano seconds has not worked for me at all, again even on previously exported files. It is now a useless app; and Apple do not seem bothered about fixing it, especially as they probably want you to upgrade to some pro software.

This didn't work for me. 😟 I've been re-editing and exporting this particular video for over a year with zero issues until I upgraded to High Sierra and the latest release of iMovie.

It happens 7 seconds into the video. I tried trimming the first few frames, but it didn't help. It's a single file with no transitions, so my only option now is to move the whole project to Premiere Pro CC...which I really don't want to do if possible. 😟

Very helpful, thank you ! Seems that faulty clips have a dark line near the top of the clip in the timeline. I managed to replace them and think all’s well now. But i never had this problem before - was it caused by upgrading iMovie to a new version ? VERY frustrating ! Good luck everyone.

I have the same error, only imported one clip. Have tried importing other clips in new projects, to no avail.

Am on the latest OS. Problem is iMovie *****. It was simple to use and then it was upgraded to this newer version. Nothing intuitive about it. Also, going to export the file, filing it under "Sharing", what is this, kindergarten?
