This triangle indicates that the project cannot locate the original video clip or audio file that was added to the project. The yellow triangle warning looks similar on all iMovie for iOS devices. An iPod touch example is shown here:
To resolve this issue:
- Upgrade to iMovie for iOS 1.2.1 or later.
- Reintroduce the media that was moved out of the Photos app, Camera Roll, iPod app, or Music app to its original location by syncing it in place via iTunes (or iPhoto if applicable).
- Open the affected project in iMovie. iMovie will detect which media was missing and attempt to locate the media to make it available for playback.
Missing Video clips
If your project contains a video clip that is stored in either of the following locations, moving the video clip from its location causes the yellow triangle to appear:
- The Photos app. (A video clip would be stored here if it was synced to your iOS device from a computer).
- The Camera Roll. (A video clip would be stored here if it was recorded using the Camera app, if it was imported via the Camera Connection Kit, or if it was moved to the Camera Roll from the iMovie Video Browser).
Missing Audio files
If your project contains an audio file that resides in the iPod app (iPad 2 or later or iPhone 4 or later) or Music app (iPod touch), removing this audio file from the iPod app or Music app will cause the yellow triangle to appear. If this is the case, you will be unable to play the missing file. To use that particular audio file in your project, you must import it back into the iPod app or Music app by syncing your iOS device with iTunes (the audio file must be in iTunes).
