How to Compress a Video on Mac


If you have ever had to share a video file with someone, you may have come across the problem of the file being too large to send. This is where video compression comes in handy. By compressing a video, you can drastically decrease its file size without sacrificing too much of its quality. If you are a Mac user, this article will provide you with a guide on how to compress videos on your device.

Explanation of Video Compression on Mac

Video compression is the process of reducing the size of a video file by removing some of the non-essential data within it. This can include removing frames or reducing the resolution of the video. The main purpose of video compression is to make the file size smaller so that it can be easily shared over the internet or stored on a device with limited storage capacity.

Check the Video Resolution and Size

How to Check Video Resolution and Size

Before compressing your video, you first need to check its resolution and size. To do this on your Mac, follow these steps:

1. Right-click on the video file and select “Get Info”;
2. The file information window will appear. Look for the “More Info” section and select it;
3. Under the “More Info” section, you will see the video’s resolution and size.

Set the Desired Resolution and Size

Once you have checked the resolution and size of the video, you can then set the desired resolution and size for the compressed video. Keep in mind that the smaller the resolution and size, the lower the video quality will be. Therefore, you need to strike a balance between file size and video quality. To set the desired resolution and size on your Mac, follow these steps:

1. Open the video file in QuickTime Player on your Mac;
2. Go to “File” and select “Export As”;
3. Choose the desired resolution and size from the “Quality” drop-down menu;
4. Click “Save” to export the video with the new settings.

Choose the Right Compression Settings

Lastly, you need to choose the right compression settings for your video. There are different options available for compression settings on Mac, such as H.264, HEVC, and ProRes. H.264 is the most common compression format used for sharing videos online, while HEVC offers better quality at a smaller file size. ProRes is a high-quality format mainly used in professional video editing. To choose the right compression setting for your video, consider the intended use of the video and its quality requirements.

In conclusion, video compression is an essential technique for anyone who needs to share video files over the internet or has limited storage space on their device. By following the steps outlined in this article, you can easily compress videos on your Mac without sacrificing too much of their quality.

Trimming the Video

Trimming a video can help to remove unwanted parts of the video, such as a long introduction or an outro. This can minimize the file size and make it easier to upload or download. Follow these simple steps to trim a video on Mac:

How to Trim the Video Before Compression

Step 1: Open the video file in QuickTime Player on your Mac.

Step 2: Click on the “Edit” tab in the top menu bar and select “Trim”.

Step 3: Use the yellow sliders at the beginning and end of the video to trim it down to the desired length.

Step 4: Click “Trim” to save the edited version of the video.

Step 5: Click “File” in the top menu and then select “Export As”. Choose the desired export settings and click “Save”.

Trimming a video can help to reduce its size and make it more manageable. This is especially useful if you have a long video that you want to share with others.

Consider Reducing Video Length

You can also reduce the video length to decrease its file size and increase uploading and downloading speed. Here are some tips to do that:

– Use a script or storyboard to plan out your video and focus on the most important parts. Cut out any footage that does not add value.

– Shorter videos tend to be more engaging and easier to consume. Keep your video between 2 to 5 minutes if possible.

– Use jump cuts to quickly move from one part of the video to another. This can help to keep the video flowing and make it more interesting to watch.

By reducing the length of your video, you can make it easier for people to view and share.

Be Careful with Audio Settings

When compressing videos, it is important to keep the audio settings in mind. This is because compressing the video can have an impact on the audio quality. Here are some tips to keep in mind:

– Choose the appropriate audio format based on what you will be using the video for. For example, if you are sharing the video online, then AAC is a good choice as it is widely supported.

– Make sure the audio bitrate is not too low as it can cause a loss in quality. A good bitrate to choose is around 256 kbps or higher.

– Test the video after compression to make sure the audio quality is still good. If not, try increasing the audio bitrate or using a different audio format.

By being careful with the audio settings, you can ensure that your video sounds just as good as it looks.

Exporting the Compressed Video

After you have successfully compressed your video, the next step is to export it in a format that works best for your intended purpose and audience. This process involves selecting the proper export format, choosing the correct export resolution, and adjusting the export settings to achieve the optimal results.

Select the Proper Export Format

Choosing the right export format is crucial in achieving the desired outcome for your compressed video. Some of the popular export formats include MP4, MOV, and AVI. The format you choose will largely depend on the device or platform you intend to play the video on.

For example, if you plan to distribute the video online, MP4 is a great choice as it is a widely accepted format that offers a balance between file size and quality. If you want to edit the video further, MOV is an excellent format as it preserves the original quality of the video. AVI, on the other hand, is a format that is mainly used on Windows computers.

Choose the Correct Export Resolution

The export resolution is another important factor to consider when exporting your compressed video. The resolution determines the quality of the video and the file size. Choosing the right resolution can be a bit tricky as you need to balance between quality and file size.

If you are exporting the video for online streaming, a resolution of 720p or 1080p is usually sufficient. However, if you intend to display the video on a larger screen, such as a TV or projector, you might want to consider a higher resolution. Keep in mind that the higher the resolution, the larger the file size.

Adjust Export Settings for Optimal Results

Finally, you need to adjust the export settings to achieve the optimal results for your compressed video. These settings include the codec, bitrate, frame rate, and audio settings.

The codec is responsible for compressing the video data. H.264 is one of the most popular codecs as it provides a good balance between quality and file size. The bitrate determines the amount of data that is used for each frame of the video. The higher the bitrate, the better the quality of the video, and the larger the file size.

The frame rate is the number of frames that are displayed per second. A higher frame rate results in smoother motion, but it also increases the file size. Finally, the audio settings determine the quality and format of the audio track in the video.

By selecting the proper export format, choosing the correct export resolution, and adjusting the export settings, you can achieve the optimal results for your compressed video. With these tips, you can easily compress your video on Mac and export it in the most suitable format for your needs.
