To import media in the A/V editing rooms, follow the 'Equipment in the A/V rooms' guide to ensure that you are logged in to the iMac computer, and that the importing device(s) you plan to use are powered on and connected.

Open the iMovie software. 

If you are resuming an editing project you’ve already begun, select the project. Otherwise, select Create New.

To import the media you wish to edit, press the Import Media button in the center of the screen.

You can import media from one of the three different tape recording devices highlighted in Guide 1. The formats these recording devices support are VHS, Digital8, 8mm, and Hi8. To import these video formats, follow the steps to record video in Guide 1, and select the Canopus ADVC-100 Camera as your import location.

If you are importing media from your U: drive, the external disc drive, or an external hard drive, select the location of the file from the Devices list.

A preview of the selected media will appear in the viewing window, allowing you to either select a portion of the video or the full video. A timer at the top of the preview indicates the length of what will be imported. Click Import to add the media.

Imported media will appear in sequential order on the timeline located on the bottom of the iMovie page. Here, clips can be selected, rearranged, and edited.

A list of all imported media can also be found under the My Media tab. Audio files can be imported, and will appear as green waveforms in both the timeline and My Media.

Once your clips have been placed on the timeline in the desired order, you can trim clips to a specific length. Select the clip to be trimmed, and drag the white handles at either end of the clip to the desired start and end points.

You can add transitions between your clips by clicking on the Transitions tab at the top of the screen and selecting the one you want to use. Drag and drop it between two clips in the timeline.

iMovie has other options for editing and fine-tuning your video clips, including adding filters, adjusting colour balance, speed, cropping, and stabilization.  These options can be found in the settings bar above the preview screen.

You can add audio from iMovie’s library of sound effects and music by clicking the Audio tab at the top of the screen and selecting the file you want to use. Drag and drop it onto the timeline below your video clips in the same way as imported audio.

Adjust the audio levels of your video clips and audio tracks by clicking on the clip or track and using the volume slider to adjust the level.

iMovie has other options for editing and fine-tuning the audio of your video, including adding audio effects and reducing background noise.  These options can be found in the settings bar above the preview screen.

You can add titles, captions, and credits to your project by clicking on the Titles tab at the top of the screen and selecting the one you want to use. Drag and drop it onto the timeline at the appropriate point. Backgrounds for captioning can also be added, and are found in the Backgrounds tab.

Preview your project by clicking at the start of the timeline and pressing the Play button at the bottom of the preview screen. Make any necessary adjustments and preview again until you are satisfied with your completed project.

Projects are saved automatically and will reload after closing iMovie.

When your project is complete, you can export your video by clicking on File in the menu bar at the top of the screen and selecting Share. Selecting File will allow you to save the video as a specific file type. As with other VIU computers, saving to the desktop is not recommended - instead, save to your U: drive or preferred cloud storage.

Choose the format and resolution you want the movie to be exported as and click Next to start the exporting process. iMovie will provide an estimated export duration and completed file size.
