Fix or change iTunes 6 video thumbnails

Here's a slick and easy tip for those of you who have videos in iTunes 6 who's thumbnail image is either missing, or if you'd like to change which shot of the video is used for the thumbnail.

All you have to do is open the video in QuickTime Pro, find the scene you want to use for the thumbnail, and chose View > Set Poster Frame. If you need an easy way of getting to your video that's buried in the iTunes library folder, simply select the video in iTunes and chose File > Show Song File or use the shortcut cmd + r.

QuickTime will ask you to save the video file once you've set a poster frame, and once you go back to iTunes you might need to actually play the file for iTunes to catch the change, but that's all there is to it.

[UPDATE: a few TUAW readers have commented there's an easier method. While playing a movie (non-DRM) in iTunes or with the movie paused, whether the movie has its own window or if its in the "now playing" pane, you can right-click the video and chose "Set Poster Frame" right within iTunes. Thanks everyone!]
