A LibGuide on how to use iMovie to create your own videos

Editing Video

There is a lot to discuss when it comes to editing.

  • Starting with the timeline, you can shorten clips by grabbing one of the ends towards the other.
  • If you go too far, you can use the "undo" command to undo the action.
  • You can also split the clip by right-clicking and selecting "split clip," allowing you to move the individual pieces around or delete the piece you do not want.
  • Other ways of modifying clips is the "trim to playhead" command which times a clip to to where you have the playhead placed in the timeline. 
  • You can also select the clip itself and then go to "clip information" in the upper right corner to alter the duration, but it can be difficult to visualize. 
  • For more precise edits, you can use the "clip trimmer" by right clicking on the clip and selecting the option. This allows you to edit the length of the clips without worrying about having to use the undo command, but make sure you close out when you are finished editing. 

Using the "clip trimmer" command on an audio clip

 

After selecting a clip you will see a preview of the clip along with some editing tools in the upper right portion of the window.

 

 

 

 

 

 

 

 

 

 

 

 

1. The first tool is "color balance" which allows you to adjust the color values of your selection. Normally, "auto" will be enough, but there are three other options available for additional adjustment. "Match color" allows you to adjust the values to match another frame in the video. "White balance" and "skin tone balance" adjust the color of your footage depending on what on the frame you define as “white” or “skin tone”

2. The next option is "color correction." This allows you to adjust colors more specifically. The first (blue) bar adjusts the shadows. The second (rainbow) bar adjusts the saturation of the colors. The final (yellow/blue) bar adjusts how warm or cool the colors appear.

3. The third option is "cropping", with the options of "fit," "crop to fill," and "Ken Burns effect." Fit essentially is the default, where the frame embodies the entire clip as filmed. "Crop to fill" allows you to control how much of the image you want in the frame while the "Ken Burns effect" introduces a slow zoom-in (or zoom-out if you want to do it in reverse). There are also options to rotate the image, as well as reverse the start/stop point for the Ken Burns Effect zooms.

4. The fourth option is "stabilization" where there are options to stabilize shaky video as well as rolling shutter. The shaky video option allows you to control how much stabilization you want based on a percentage (33% is the default) while the rolling shutter option has options from "low" to "extra high" that allows you to adjust how much motion distortion there is.

5. "Volume” is the fifth option. You are given two sliders, the one on the left adjusts the volume of your selected clip and the one on the right adjusts the volume of any clips playing at the same time as your selection.

6. The sixth option is "noise reduction" which adjusts the background noise, whether by the volume as well as set an equalizer for it, whether reducing the hum, boosting the bass, and several other options to try out.

7. The seventh option controls the speed, which lets you adjust how fast or slow your footage moves. There are also other options like "reverse", which plays the video in the opposite way (mirror), and "preserve pitch" which maintains to pitch of your audio while adjusting speed.

8. "Clip filter and audio effects" is the eighth option adjusting the filter and audio of the clips. For both, you select an effect from the options provided. These filters and effects work just like the ones you find on Instagram or Tik Tok, manipulating the image or audio in fun ways.

9. Finally, "clip information" allows you to adjust the length of the clip as well as gives some basic metadata on the clip. Not much, but might be useful.

Once you play around and get used to these options, you'll be able to make a professional-looking video!

Transitions, titles, and credits are relatively simple to insert. You just select the tab they are under (upper left part of interface), select something you like, and then drag them down and position them in your movie however you like.

  • Transitions typically go between two separate clips while titles and credits are essentially clips themselves for all intents and purposes. 
  • For titles and credits, you can edit their text by selecting the clip and then double click the text in the upper right portion and type in what you want.

Unlike with a movie, choosing the "trailer" option gives you the option to choose from one of several templates of varying lengths and content. After selecting the template, the upper half is more or less the same, but the bottom half has a noticeable difference: there are three tabs: outline, storyboard, and shot list instead of the timeline.

  • The outline is responsible for assigning the information displayed in the trailer such as the movie title and credits.
  • The "storyboard" is where you put all assets you want included in the trailer such as video, audio, and text.
  • The "shot list" helps organize what clips and other assets you want to use by type like action and landscape, which can help with planning and structuring your trailer.

To select a specific clip to use in part of the trailer, select the part you want to insert the clip into and then select the part of the clip you want to insert. It will automatically insert the part you select, and even if you get it slightly wrong, you can adjust and select again.
