Why is my iMovie not full screen on Iphone? It is possible to increase the resolution of the video to make it look bigger, but this will likely increase the file size significantly as well. This process can sometimes lead to a noticeable decrease in quality, although this is often negligible when you look at it on a small screen.Ĭompression can also make the video appear smaller on the screen than it originally was. Video compression is necessary for iMovie to be able to store the video on your device and give you the option to upload it.Ĭompression involves removing some parts of the video that are not essential, such as color and sound, in order to make the file size of the video smaller. IMovie probably made your video smaller because it’s compressing the video to reduce its file size. When you are confident that you have chosen the correct settings for your output you can then press ‘Done’, and iMovie will then begin encoding your video which will be output in the resolution that you specified. If you do choose to select a smaller resolution, such as ‘Movies 720p’, then your video may still be cropped as the resolution is smaller.Īdditional settings such as frame rate, video codec and audio codec can also be adjusted as required. The most common resolution is to choose ‘Full HD 1920 x 1080’, as this will ensure that your movie is not cropped when you export it.
