How can I add black bars to convert SD to HD aspect ratio? Hi,I have some 720x480 standard-definition video that I’d like to edit with iMovie. The description that you posted of how to do it is a bit confusing, but essentially it is similar to the above procedure.Īnother way would be to export the vertical video and crop out the black bars by using the New Screen Recording feature of QuickTime Player. As you can see, it is not exactly quick and easy.

Open in QuickTime Player and rotate back to vertical. Then you rotate the title 90 degrees and position it on your video with the Picture in Picture feature of iMovie. Then you can make a title on a transparency screen in a photo app outside of iMovie, such as the Preview app on your Mac, and import that into iMovie. To get rid of the black bars in the exported final product, you can rotate the video 90 degrees so that it fills up the screen. The actual video portion as displayed will be smaller than full size. If you don't mind the black bars you can add a title to the 9:16 vertical movie and export it. If you have a vertical 9:16 video you will get black bars on each side to make it fit iMovie's 16:9 screen. Unfortunately iMovie has a 16:9 aspect ratio that cannot be changed. Sad that the little tetra overate and met a regrettable ending. You obtained a great result with your video and I would stick with whatever procedure that you used.
