I ran in to an odd issue with iMovie – it wouldn’t let me export the project to a file at 1080p, it would only let me select 720p or 540p. This was a bit odd – I checked all the source footage and it was all at least 1080p? Anyway, there’s a simple way to fix, and it involves:
- Select all of your project footage with CMD+A, and then copy it with CMD+C.
- Create a new project, and insert any photo in there – it has to be at least 1920×1080, so any decent resolution photo.
- Paste in your project data with CMD+V.
- Delete the photo you inserted….
- …and you can now export in 1080.
Bit weird, but like I say, quite simple to fix. The video below shows a run through on how to do it.
