Users of the newly redesigned iMovie app are seeing red after upgrading to OS X Mavericks. There's a strange glitch that gives some .mov files a red tint when imported into Apple's movie creator, while other file formats seem to be unaffected. The video files are discolored in both the Clips View and when previewing the edited project. Exporting the movie maintains the incorrect colors.

Like many of Apple's desktop apps, iMovie was completely redesigned for Mavericks. iMovie is part of the iLife suite of applications, which Apple just announced will be free with the purchase of a new computer — but you may want to wait for a fix before doing any major iMovie editing.

We've reached out to Apple for comment.

Thanks for the tip, Josh!
