Join John Nastos for an in-depth discussion in this video Editing and exporting your video in iMovie, part of Distributing iOS Applications Through the App Store.
- Now that you have some raw video footage from the device, I'm going to show you some of the basic steps to create an App preview video in iMovie. Apple has a page on their website that describes this process. I won't get into any heavy editing or advanced features of iMovie here, but if you'd like to learn more about that process, check out iMovie Essential Training. In iMovie, the first thing I want to do is import my clip. I can do that from the File menu, and the Import Media item. Then, I'm going to look for my clip, which I have put in the Exercise Files under App Preview Video.
Then, I'm going to go to the File Menu again, and make a new App Preview Video. At this point, I'm ready to add some of my video to the timeline. So, I don't want to include the entire video since it's too long anyways. It's 45 seconds and my App Preview can only be 15-30 seconds. So, I'm just going to select a small portion of this video and drag it onto the timeline. Then, maybe I want a portion from later in the video, so I'll select that, and drag it into the second part.
Now, to link these two sections together, I want a transition. So from the Transitions Library, I'll choose the Cross Dissolve. Now, I have footage of the App, but I don't have any text telling people what it is. So, I'm going to choose from the Titles option, and I'll put a full screen title right at the beginning. And I'll make my text say "Distribution Example." Also, part way through my video, I'm going to put one of these colored bars at the bottom.
And I'll just have it say "Demo." At this point I'm going to watch some of the video, looks good so far, jump up to the point where the Demo item appears and that looks good too. But, at this point, everything is silent. So, I think I want to add some music. I'm going to go to Import Media again, and this time, I'm going to choose this MP3 that I have in the audio folder in the Exercise Files. Then, I can drag the MP3 into my timeline.
The MP3 is way too long for my clip right now, so I'm going to drag the end so that it matches up with the end of my App Preview Video. Once I've done that, I'm going to take the fade out volume at the end of this MP3, and I'm going to drag it so it keeps fading with the end of my video. And I'll play the end of my video to make sure this all works. (soft rock music) That all looks good to me, so at this point, I think I'm ready to export this video, which I can do in the File Menu, go to Share, and then choose App Preview.
You'll notice that the resolution is the same resolution that I recorded with the device, and it's going to be encoded in H.264. It's also 28 seconds which is perfect because the time limit is 30 seconds for these videos. Then, I can export and save the file.
This course covers preparing an iOS application for, and submitting it to, the App Store. It includes tutorials on making sure your app meets Apple's human interface guidelines, preparing assets such as icons and screenshots, building preview videos, generating the necessary development and distribution certificates, building the app bundles, submitting the app, and complying with Apple's requirements for marketing materials. Author John Nastos, creator of the popular Metronomics family of apps, will also explain what Apple's review process is like and how soon you can expect to hear back about your submission.
The course will be updated as Apple's requirements evolve, so check back often to keep your skills current.
