The size of the largest media used in the project determines the final movie sizes you can render.


If you’re unable to select the larger sizes, the original project media isn’t large enough to render in that size. This topic explains resolution in more detail: About image resolution of shared projects. The resolution of the exported movie for each size depends on the aspect ratio (standard or widescreen) you chose when you created the project. The table shows which sizes are best for each viewing device or location, and the resolution of each size (how many pixels it contains). Select the size of movie that best matches what you’ll be using the video for. If the location you want doesn’t appear in the pop-up menu, click the blue Arrow button to the right of the Save As field, and then navigate to the desired folder. Type a name for the movie in the Export As field.Ĭhoose the location where you want to save it from the pop-up menu. The Share menu appears in a light gray bar across the top of your computer screen. Changing the dimensions would require cropping or there would be distortion.In iMovie, open the project or select it in the Project Library, and then choose Share > Export Movie. However, the resolution you see will be determined by the resolution of the display screen. When you share out you will be given some resolution options that bracket the resolution of the project to be shared out. The resolution of a project (480, 720, etc.) will be set at the resolution of the very first clip placed into a newly created project. However, after you share out the movie to your desktop you can crop out the black bars in the shared out movie by opening it in QuickTimePlayer and doing a File/Screen Recording, where you can outline the dimensions of the video that you want to record, eliminating the black bars. No way to avoid that unless you crop the video to "Fill". However, there will be black bars to make the display fit the 16:9 screen.


You can display a 4:3 video in its original aspect ratio by setting the crop setting to"Fit". IMovie's 16:9 aspect ratio of its screen cannot be changed.
