Help with iMovie- Error message 10008

I got the same "Video rendering error 10008" while I was trying to save my video to file. I spent 2 full days making and remaking the video (I had 10 video clips, stills and title boxes in the project). I also spent 5 hours on the phone with Apple support -first hour was spent with a girl who promised me she was an iMovie expert before she gave me over to an IT guy who knew what he was talking about. During my support guy's lunch break, I looked at my video clips frame by frame and found one of my video clips had one bad frame. I removed the bad bit and put the video back together and it worked well. Unfortunately iMovie is not good at showing you where a problem exists! My guy is doing some research to see if Final Cut Pro has a way to easily find corrupt video. Will post if he replies, or if anyone here knows the answer, I hope you will share!

I can confirm the issue was with one video that was corrupt.

I split/deleted a few videos at a time and exported to nail down which video had the corruption.

It would be nice if the engineers at Apple could...

1. Didn't let the user import the video due to a corrupt frame(s)

2. (Bonus Points) Let the user import the video but offer to attempt and repair the corrupt video by removing the corrupt frames

3. (If you can't) Please change the error code 10008 to "Cannot import due to a corrupt frame at... <1:23>" It's tedious for us to go through the videos to find the corruption.

I have never had this problem until January 24, 2016. Then when doing and i-Movie I got the dreaded 10008 error message. After reading some of the responses and seeing that the problem was with a corrupted video or picture, I went back and watched my own video. It worked fine in the "project" section, but was corrupted in the "theatre" section. From the theatre, I ran my video. Unlike most of you, my video is really of pictures only, NO video in my project. As I was watching the playback in the "theatre mode", I noticed part way through, a "jiggle" when it got to a particular picture. I figured that was the problem. I went back, deleted that picture from the project, and now it works great! No error messages!

I hope this helps. Those of you who mentioned corrupted data gave me the idea and from there was able to solve the problem.

yes, best advice - same issue - a few black frames to cut out..not sure why, probably 'corrupted' or dropped in some way, but the fix worked for me too.

These Apple discussion forums are a lifesaver - no two ways about it!

I was able to close iMovie, turn off WiFi, restart iMovie, and it worked!

Thank you this helped me. iMovie created a partial file, i went to the end of this file to see the time stamp then went to the same clip in iMovie and trimmed the clip. That did the trick.

A few of my clips had a few bad (black) frames in various spots causing the share to fail when the rendering reached the point of each bad frame. Carefully scrubbing to the bad frames and removing them, by splitting the clip and scrubbing past the bad frame finally solved my sharing failures. Not sure if my camera is causing the bad frames or if the import process is somehow causing it. I didn't have this problem until recently.

As described by docmo18, by watching the partially shared file, I was able to see where it stopped rendering. Then I went to that point in iMovie to remove the faulty frame. By eliminating just one frame in each spot, carefully, the clips still play smoothly.

Thank you docmo18.

Ran into this problem yesterday with the latest version of iMovie 10.1.2. Tried rebooting my Mac and restarting iMovie, didn't help. Scrubbed the timeline for black frames, found the spot. It was where a title bridged a split clip. Moved the title away from the break in the clip and the black frames disappeared. This fixed the problem and rendering completed.

So, apparently it's not just corrupted files in a clip because I did not remove any part of the offending clip, just repositioned a title.

I have read all posts regarding this issue and tried everything. I have a 43min movie and have scrubbed clean, moved/deleted titles, changed clips and still no joy. It's the same outcome always. It creates a file to 7 secs, but is audio only. I was given this project to complete from a friend on an earlier version of iMovie, I have the very latest update like yourself 10.1.2 and imported the whole library. I have spent quite a few hours stripping what he'd done to adding new footage, new titles etc, but the transfer from old seemed easy with no issues. I have not done anything I haven't done before, but now this error code. Arrrrgh! I need to make a large batch of DVD's. We did use a variety of cameras and have avi, m4v and mov formats whilst skiing. This shouldn't be a problem as it hasn't been in the past, I hope. Don't want to convert every clip! Also what format would work bedt anyway? Can anyone shine some light? Please!

Happy days!!! it was indeed a problem with a corrupt movie file .mov. I couldn't find it by scrubbing through the full timeline for some reason, so, I broke down the full 43 mins to 'chapter' segments that were naturally within the project anyway (not chapter markers), copy & pasted to new projects and exported individually a chapter one by one. It was during the 5th chapter export where immediately it failed. I changed the clips one by one as it was more managable in 4 min chapters, but still no black frame. I scrubbed the original clips in the media section and eventually found the culprit. It was the only 'mov' file amongst 'gopro' and 'img' files. No matter how much cutting/splitting/range picking I did it just kept creating extra black frames. I just got fed up and deleted the entire clip and replaced with a different clip.

Exported fine, and just need to copy and paste this 'chapter' back into the full project.

I hope this adds to troubleshooting ideas guys, it really annoyed me as it was slightly different from other problems I've read, but thanks for the tips so I could start looking!!

oh and in regards to only creating a 7sec audio file?? No idea why this happened, would have been nice if it was like previous posts 'created a file to the point of error', could've found it straight away.

Enjoy!

I'm glad you worked it out. iMovie sure does seem temperamental these days.

"It was the only 'mov' file amongst 'gopro' and 'img' files"

Have you been able to export GoPro files using iMovie? I kept getting the error 10008 and only now discovered that GoPro files aren't compatible with iMovie - I've spent so long editing footage all taken on my GoPro and the files need to be changed in CineForm studio software - except I just read that GoPro isn't linked with CineForm anymore. Do you know if I need to find all the original clips and convert them for iMovie and start everything again, or is there a way I can keep everything I've worked on and convert it all together?

There was quite a bit of GoPro footage amongst other HD vidcam footage. Everything exported as usual after I found the offending clip. It was my mate that uploaded them (his first time using iMovie so he would have just plugged and imported) so I was out of that part, it was strange about the .mov clip and that every other clip was .img when I was scrubbing over them in events although they were a mixture of imports and showed up as .m4v in the files on my mac. The GoPro should be fine. There were numerous gopros here as they were from my students, also an older HD standard headcam, iphones and Sony HD video cams. For only one clip to be different/dodgy/corrupt was odd. I am going to purchase a gopro myself in a few days so if I do come into difficulty with it I will add to the post.

I am trying to get to grips with Final Cut Pro X too but have read similar problems.

I'm sure you've resolved this problem by now, but just for future people who see this problem... I'm running iMovie off of an external drive with a library on that drive as well. I had a 2 minute movie and got this error about an eighth of the way through exporting.

I saw someone talking about separating out the chapters, trimming out black frames, and thought, "oh my God I'm absolutely not doing that" and copied and pasted everything into a new project using the same library and it exported just fine.

#imovie, amirite?

Hi, I am having the same problem as you were. How were you able to tell which video clips were currupted? Thanks in advance.
