Part 2. Recommended MP4 Cutter for Mac (3 Methods to Compress MP4 Videos)
Many videographers work with Mac computers because of the many special creative features. If you want to learn how to compress MP4 files on a Mac, you can look to MP4 cutters for help. Three ways to compress MP4 files with Wondershare UniConverter on a Mac include:
- Trimming videos
- Compressing with customized bitrate, frame rate, and encoder video settings
- Changing to a small-sized file format like FLV or WMV
To get started, download the Mac version of the Wondershare UniConverter MP4 compressor to your computer.
Method 1: Trim video
Trimming a video of unnecessary parts easily resizes your file. To trim your video with Wondershare UniConverter, simply:
- Add the video file to Wondershare UniConverter
- Click “trim”
- In the trimming editing window click “cut” to select the film segment you want to cut.
- Click “delete”, “merge all segments”, and then “OK”.
- After setting it up, choose MP4 as your preferred format and click “start all”
You can cancel the process at any time if you change your mind, or want to trim a different portion of the video.
Method 2: Compress with custom settings
To begin customizing your video to shrink MP4 files on Mac:
- Add the desired file to the MP4 compressor. Click “add files” or drag and drop the file. You can add multiple video files at a time.
- Select “output format”, “video”, “MP4”, and click the editing icon to change the settings manually for cutting down video size.
- Click “create” to compress the mp4 video.
Some of the specialized settings you can choose from to compress MP4 videos include:
- Frame rate: The frame rate is the number of frames per second displayed consecutively. The video is made up of individual frames. The rate at which they are played ensures seamless playback creating the appearance of motion film. Use Wondershare UniConverter to choose rates like 23.97 fps, 24 fps, 25 fps, 29.97 fps, 30 fps, 50 fps, 59.94 fps, 60 fps, and more.
- Bitrate: The video bitrate is the amount of data transferred per second in a video. Video data are video bits, hence the name bitrate. The higher the bits per second (bps), the higher the quality, and larger your video file is. Lowering the bitrate in Wondershare UniConverter shrinks the MP4s.
- Encoder: Encoding a video converts it from a RAW file to a digital file. This lets you share it digitally, and in the process, alters the size of the file.
- Resolution: Like an image, your video resolution is measured in pixels. The higher your video resolution, the bigger the file and the better the quality. Reducing resolution compacts the MP4 file.
Method 3: Change to small sized format
Converting MP4 files to alternative formats for different-sized storage. Moving your MP4 to an FLV or WMV, for example, lets you maintain the film length, bitrate, and resolution, but in a different format. Wondershare UniConverter lets you convert to more than 1000 different file types.
Use these steps to get started:
- Open Wondershare UniConverter and select “converter” on the home interface.
- Click “add files” to import your video.
- Once the file is added, select “output format” from the “video” tab (FLV or WMV are good choices to reduce file size).
- Select “high speed conversion” and click the destination folder.
- Click “convert” or “start all”.
The MP4 video conversion will process quickly, and seamlessly.
