Apple has released iMovie 10.1.7, adding support for the new High Efficiency Video Coding (HEVC) format used by macOS 10.13 High Sierra and iOS 11 (see “HEVC and HEIF Will Make Video and Photos More Efficient,” 30 June 2017). The update also improves compatibility when sharing videos to YouTube. iMovie now requires macOS 10.12.2 Sierra or higher. (Free from the Mac App Store, 2.14 GB, 10.12.2+)
I have a 2011 model MacBook Pro. Ever since updating to High Sierra and updating the iMovie app, I now get a “failed to export” error for any manner in which I try to export the video. Any help would be appreciated!
I am having the exact same issue with my 2017 Macbook Air since updating to 10.1.7. My error is 10004.
I have the same problem!!! sucks!
