So basically I 've got xcode and my animation is done and has been exported as a .mp4 How do I tell Xcode to turn that file into a .saver file. The end goal is to be able to provide the file as a download for users to have as their custom screensaver. Note. I have this file in .mp4 format as well as a .qtz file which the Quartz file was made using the .mp4 as well. Because the animation was originally created in After Effects. Please if anyone could help me on this subject I'd truly appreciate it it's the one thing from stopping from being able to create custom screensaver for clients. Also if anyone knows of a great tutorial on making a live or moving wallpaper utilizing some what of the same scenario utilizing an already premade .mp4 animation. Thanks.
