How to Trim a Video on Mac [6 Ways] 

Mac users are a lucky lot. That's because Mac computers come baked with free utility tools like QuickTime Player. Apart from playing videos and audio, this tool can also help you trim video in Mac. And if this Mac video trimmer doesn't work for you, iMovie is readily available to install for free as well. But there's a problem; these free Mac programs can be basic and one-dimensional at times. For this reason, I've prepared a list featuring the best video trimmers for Mac to consider as alternatives. Let's trim videos!

Part 1. How to Trim a Video Using QuickTime on Mac

As mentioned initially, QuickTime is a handy pre-installed software for Mac OS X. It can play, trim, and record videos and audio with ease. Speaking of trimming, QuickTime Player lets you cut, split, and rearrange clips. And the process won't take you more than 20 seconds to complete.

Follow me:

Step 1. Launch the movie or video you want to trim on QuickTime Player.

Step 2. Then, click Edit and choose Trim. Or tap Command + T shortcut to launch the trimming tool. You can now drag the yellow handles on the timeline to reduce the video's playback durations.

Step 3. If satisfied, tap Trim to save your new video. It's that simple!

Part 2. How to Trim a Video on Mac with iMovie

Try iMovie instead if you're unimpressed by QuickTime's video trimming capabilities. With this free Apple program, you can trim MP4 on Mac and iPhone. Apart from cutting videos, iMovie also lets you rearrange, split, crop, add filters, apply effects, and so on. It also has a huge library with hundreds of royalty-free music and sound effects. Overall, it's the best free video trimming software for beginners who are unwilling to pay for an editing program.

Here are the simple steps:

Step 1. Search and download iMovie from Mac App Store and launch it. Then, add a New Project.

Step 2. Tap Create New, choose Movie, and then click Import Media to load the video you want to trim.

Step 3. Then, drag and drop your movie to the timeline before highlighting it. Then, drag the yellow handles at both ends of the clip. Alternatively, place the playhead where you want to start trimming and then right clip the video track and choose Trim to Playhead.

Part 3. Other 4 Video Trimmers for Mac Recommended [2022]

Although free video editors are irresistible, they come with some limitations. For example, iMovie and QuickTime Player aren't for advanced users because they cannot trim exact video playback durations. In other words, you can't enter the time to start and stop time for your new video. For this reason, I recommend these four professional programs.

1. Wondershare UniConverter

Wondershare UniConverter is the best beginner and professional program to cut video on Mac and Windows. It comes with a manual video trimmer that allows you to enter the precise time to begin and stop trimming. For beginners, you can simply drag the trimming handles on each end. But that's just half the story; UniConverter boasts an AI-powered Smart Trimmer to auto-select video scenes to eliminate. In this case, you set the program to select and trim based on audio volume, buffer, and duration. And yes, it has other features for cropping, compressing, applying filters, rotating, recording, downloading, etc.

Below is how to auto-trim videos on Mac/Win with Wondershare UniConverter:

Step 1 Upload a video on the Smart Trimmer.

Install and launch Wondershare UniConverter on Mac and then open the Smart Trimmer on the home window. After that, tap Remove Silent Segments before dragging and dropping your video or clicking Add Files to upload them.

Step 2 Enter the audio presets.

After successfully loading the video on the Smart Trimmer, enter the audio volume level, playback duration, or buffer rate. For instance, set the Smart Trimmer to auto-select video scenes with an audio playback duration of below 10 seconds.

Step 3 Trim and export the video.
