 A how-to guide on editing your video on an iPhone or iPad. Now that you have started an editing project, you are ready to begin editing. You'll want to begin by adding clips to your timeline. To do this, find your media panel and select the video icon. Choose All to view all the videos available. Now select the clip you would like to add to your timeline. You can choose a section of the clip by sliding the yellow bars to the desired portion. To preview the clip before placing it in the timeline, select the play key next to the clip. When satisfied, choose the down arrow and the clip will be added to the timeline. Repeat these steps for each clip you would like to add. Once you have added your clips, you can view your video by choosing the Play button at the top center of your timeline. You will notice that iMovie has automatically added transitions between each of the clips added. Transitions should only be used for a specific purpose. For example, to show a before and after, or to emphasize the passing of time. Otherwise, transitions are not necessary. To remove the transitions, select the small square between each clip and select none at the bottom of your screen. After viewing the clips in the timeline, you may decide you want to make changes. To do this, select the clip you would like to edit in your timeline. Slide the yellow bars to lengthen or shorten your clip. You may also continue to hold your finger on the clip and drag it to a different section on the timeline. You can split a clip by moving the play head to where you want to cut it. Select the clip and then choose the scissor icon labeled actions below the timeline. To delete a clip, highlight the clip, then select the trash can at the bottom right corner of your screen. To undo an edit, select the curved arrow at the top right corner of the timeline. To edit your audio, select a clip and choose the volume icon below the timeline. Now, slide the bar to the left to lower and to the right to turn up the volume. If you select the scissor icon labeled actions and choose Detach Audio, your audio will separate from its video and you can edit the audio independently. To add music or sound effects, select the audio icon in the media panel. The first two options that appear are Theme Music and Sound Effects. Both of these are provided by iMovie and free to use. When adding music or audio that you have not recorded in your video, it is crucial that you have permission to use these pieces of audio. Severe legal consequences can occur if using copyrighted music without permission. To add titles to your video, select a clip and choose the T icon labeled titles at the bottom of your screen. You may now choose between a variety of options. Placement options can be selected below the titles. To add your title, select the title on your video and add your text. Titles should be on screen for at least three seconds. When you are ready to export your movie, select Done on the top left corner. Select the box with the upward pointing arrow. Then, save video. Choose HD 1080p. Final video should be no longer than three minutes. Once your video is exported, you can find it in your Photos app. You now have the tools needed to create a video from beginning to end.
