how do I change the thumbnail in iMovie project
The frame that I want to use is the very first image in my movie. How can i make it my project thumbnail ?
iMovie randomly selects a frame from the middle of the movie to set as the thumbnail for the project. There is no easy way to change this other than to add some black backgrounds to the end of the movie, or add transitions to the movie, to change the mid point of the project. However, that would not result in making your first image the thumbnail for the project.
Someone on this forum did devise a method to change the poster thumbnail in the Theater display. The only thing is that I am not sure that the reset thumbnail will stay when the movie is dragged from the Theater library onto the desktop. I did a test myself but the thumbnail did not hold. However, if you want to try it you can take a look at this link:
