Imported video get red tint
I'm doing some video editing in iMovie 10.1.8 running on a MacBookPro 17 min 2010 with macOS High Sierra v 10.13.3.
The videos is digitized from Hi8 and stored im mp4 files.
Some of the files works ok, but some gets a red tint over the whole video file.
The same files plays perfectly in QuickTime.
Any fix for this?
