Whether you're hoping to edit short TikToks, or longer Youtube videos, iMovie is a useful and simple software to use for all your needs. It comes pre-installed on any Mac OSX devices and features cross-compatibility with other, more-robust video editing platforms like Premiere Pro.
1. To find iMovie, press on Finder, and search for iMovie in your Applications folder, and press on the purple icon, with a video camera in it, as shown to the right.
2. When opened it, should look like this. Press on the 'plus' button to start a new project in iMovie.
3. Two options should pop up: the ability to make a Movie or a Trailer. If you select 'Movie', you will have the greatest amount of freedom to edit your videos and will allow you to do about anything. Selecting the 'Trailer' option will allow you to insert your video footage into a variety of pre-set editing and transition filters: this is useful if you want any help on seeing what good edits look like!
1. Once you've opened a new Movie project, you will be taken to a screen where you can see various ways of importing media into your project. You can import both video files and audio files into your project.
2. In order to import video files, press on the sidebar title named: "My Media" to the far left. This should open up an empty screen, with a large button saying "Import Media", as shown here. Press on this button to access your computer's files. Find the files you want to edit, and insert them into the project. Alternatively, drag the files into the iMovie browser, in order to import them more quickly.
3. When the video files are imported into your main timeline, they should have two components to them: the video image itself, and the sound of the video. You can choose to separate or delete the audio from the video files, if you just want the visual images, and wish to overlay in more music.
4. To upload music, press on the "Audio" button on the top side-bar menu. You can upload music from your computer, using the "Import Media" button once more, or you can import music in from iTunes. Alternatively, as before, you can click and drag musical files into the project, and have them appear on your timelne.
5. HIGHLY RECOMMENDED: Save all of your imported media as a Project Media Library for your project. This allows you to transfer your iMovie projects between computers, if you need to do so.
There are several elements to a Timeline. I'm going to breakdown the visual cues for some of the more common and useful parts of a video.
These are marked by a thumbnail of the full content, and when hovered over, you can see the full duration of the clip.
These video files can be tied to their own audio within the video, or they may be silent video clips. The difference between a video clip with its own sound, and one without its sound is shown below. Notice the blue strip underneath the video file: without audio, the blue strip is empty. On the video file with audio, you can see the waveform of the clip mapped out in pale-blue.
It is difficult to layer two video files over one another, but not impossible: it is best to layer two layers of video when one video frame is smaller than another, in an overlay. You can do this by making sure you are in the "frames" menu on the preview screen, select "Picture in Picture" from the dropdown box as pictured here, and then resizing your movie within each other.
These are usually represented as green boxes, and you can see the waveform representation of the audio. The waveform marks the frequency and volume of the audio in the clip. Hover over the audio clip, to see the full duration of the clip.
These audio files can be easily layered, to have several layers of sound happening all at once. You can adjust the volume controls by clicking and dragging the yellow line that is depicted here right in the middle of the audio-track.
These are depicted by little white dots on the audio file's waveform, as seen below.
Press 'option+left-click' to add a keyframe to the audio.
Keyframes are a way to control the volume of certain section of audio with more precision. If you want only twelve seconds of your audio, right in the middle of your audio to be quiet, for instance, you can adjust that by using a few keyframes to toggle only part of your audio to be quiet.
These are depicted by translucent arrows between video clips.
Double-click on the arrows to change the length of the transition to be slower or faster. You can choose from a variety of different Transitions from this button on the toolbar at the top of the screen, and drag them down between your video clips.
Text can be added into an iMovie in two different distinct visual ways.
Firstly, it can be added as an overlay over an existing video. This is useful if you want to add text, as if it is a caption, or a label to what is happening on screen.
To add captioning or labelling text as an overlay, click on the button "Titles" from the toolbar at the top of the screen, select the appropriate text location/duration from the variety of pre-set options, and drag it down, over the video file in your Timeline that you want it to label.
It should look like a small purple box, clinging to the video files.
Right click on the purple box to change the duration of the text file in seconds. Double click on the purple box, to be able to edit the text's content, font and size within the preview box, the box to the right of your screen, as shown below.
Secondly, you can add a separate text screen within a video. This is useful if you want to have a titlescreen, a credit scene, or any kind of text transition between images.
To add a separate text screen, click on the button "Titles" from the toolbar at the top of the screen, select the appropriate text location/duration from the variety of pre-set options, and drag it down into your timeline.
Place it inbetween two video files. It should look like a green box inbetween your videos. Double click on the text in the preview box, on the right-hand-side of your screen, to edit the text's content, font and size.
Narration over a pre-exiting video can be helpful in order to properly set up the timing. Although it will look the same as a regular audio file, you can in fact narrate directly over an iMovie project that's in progress.
In order to do this, select the microphone button underneath the preview screen. This will change the pause/play buttons underneath the preview screen into a red recording button.
Drag your mouse over to where you wish to begin your narration, and press the record button. You will be given three seconds to prepare yourself before you can begin narration and layer it over the video file.
Some more basic edits that can be helpful for creating the perfect short video edits!
If you want to mess with the saturation, brightness or values of your video, iMovie makes it very easy. Simply press the "palette" icon above the preview screen as shown here to open up the menu.
The slider on the right controls the "temperature" of the photo, whether the warm colours like red, yellow, orange and pink are more prominent in the photo, or whether the cool colours like blue, green, purple and are more prominent.
The slider in the middle controls the saturation of the picture: whether the picture is more brightly coloured, or whether the colours are more muted and grey.
The slider on the left controls the brightness of the picture. If you increase the top slider, the white slider, that will make the highlights of the picture brighter or darker. If you move the bottom slider, the black slider, that will make the shadows of the picture brighter or darker. If you move the middle sliders, this will change the contrast of the picture: whether bright and dark are very diametrically opposed, or not.
Finding the optimal settings for the video differs depending on the style of the video. Don't be afraid to mess around with the sliders, until you find the ideal colour-grading.
Sometimes, if you're thinking of making a timelapse video, or you want to slow down an action shot within your editing, you'll want to mess with the speed of the video, to display differently. iMovie makes this very intuitive.
Right-click on the video file you want to speed up, and select "Show Speed Editor" from the dropdown menu. This will make a small slider bar display on the top of the video file.
Drag the slider bar leftwards, and this will make your video faster. The video file will flash with the icon of a hare to indicate this. Hare is for a sped-up video.
Drag the slider bar rightwards, and this will make your video slower. The video file with flash with the icon of a tortoise to indicate this. Tortoise is for a slowed-down video.
To make it go away again, right-click the video file, and select "Hide Speed Editor."
It isn't always easy finding a pool of places where free videos or audio can be found without needing to pay royalties, but this will hopefully give you a places to start off with!
