Pink and Green Lines When jpeg used in iMovie

Although this thread is about 9 months old, I recently encountered this problem and also found a solution that helped in my situation. First, in terms of platform: MBP 2011 running Sierra (10.2) with the latest iMove 10.1.4 (I think). Anyway, the problem is essentially as the original poster indicates, whereby some images do not properly render in the preview and/or upon export.

I found a recommendation that said that the problem could be associated with the size of the image. I saw this described in terms of pixel x pixel size, as well as in terms of the file size. One post said to keep the file size less than 5MB. Some of my files were 2 or 3MB and I still had the issue. What I ended up doing was saying the files as small as possible 0.5MB (for example) and replacing the clips in iMovie. I had to replace several clips, but this appears to have helped and I've been able to render my 7 minute video!

Hope this is hopeful if anyone else is encountering this bug/defect/problem.

Thanks ScratchSF, gnacs and liztreeb for the posts. I suspect that this problem is associated with older Macs with older graphics cards since Apple is moving more and more of the video processing from the CPUs onto the graphics processors and there are more possible combinations of graphics cards and still image formats (.jpg actually encompasses a large range of sub-formats) than can possibly have been tested. When the previous problem I referred to in my earlier post was solved it was sometimes necessary to delete and re-import affected stills before the problem would go away.

I was having this issue, and it was very frustrating. After trying everything else as mentioned in all the forms I could find, I decided to share the video as a file, and I put all the settings on the highest quality possible. While this took a while to export, IT WORKED!!! No more fuzzy pink screen replacing my still images.

This type of problem was experienced with iMovie 11 running under El Capitan but not with iMovie 10.1.1. You stated you upgraded to 10.1.1 and are still seeing this problem. Try creating a new library and new project and see if you can reproduce the issue. Perhaps your iMovie 11 library didn't upgrade to 10.1.1 properly.

I don't understand iMovie 13, do you mean 10.1.1? That is the version that runs correctly in El Capitan. Am I correct in understanding that if you place a clip in the timeline and add a photo above it and for the photo select picture in picture then it plays fine in timeline but upon sharing it exhibits the buzzing green and pink lines on the movie or just the pip.

Yes iMovie '13 is now normally referred to as iMovie 10.

I have seen several recent reports of behaviour like this. It appears that there are still some photo formats that are not working with the latest version of iMovie (10.1.10 under El Capitan even though this version was reported to have solved such problems. Previous versions gave problems with stills with certain Macs and not others, (probably depending on the graphics card version) though these problems were visible in the timeline and not only after sharing. Does it occur whatever export settings and destination you use?

I can only suggest you file a bug report at: http://www.apple.com/feedback/imovie.html

giving details of your exact Mac model and the format of the affected photos. Any others with this problem should do the same.

Maybe you could also post these details here. If others with the problem do the same we may begin to see a pattern.

Anyone seen any help to this question?

If you are still experiencing this problem I found a work around after several hours with an Apple technician.

1. Back out of your project in iMovie to the "My Projects"

2. Highlight the project you are working on that is having the issue (don't double click it to open it)
3. In the edit tab "Create Duplicate" or command D
4. Once the duplicate is created select it, open it then export.

This worked for me. Hopefully it will for you as well!

I exported as a .mov and there were no pink photos

EXport as A .mp4 and after each attempt there were more and more pink

the green photos : were beaten by re-importing into a new event with a different name and also less than 5MB in size

my movie was 2hours 38 long.

ScratchSF's solution works for me too it seems (Didn't render the video yet, but in preview it looks good)!

Problem disappeared when I used a smaller image: 72 dpi - 1920x1080.
