Step 1. Import the Large QuickTime Video

Free download and install VideoProc Converter on your Windows or Mac computer. Launch it up. Next, you hit Video on the initial screen and then click on +Video to import the source QuickTime video file to the program.

Step 2. Compress QuickTime Video File

You can adopt one or multiple methods to compress QuickTime video on Mac or Windows via VideoProc Converter.

A. The One-Click Method to Compress QuickTime Video

Choose advanced codecs like MP4 HEVC, MP4 H.264, or MOV H.264. Hit Run.

Why you can compress QuickTime video by converting

QuickTime is just a container format that holds the video and audio encoded with 50+ codecs including the less-compression codecs like ProRes and the high-compression codecs like HEVC. Different codecs use different compressing technology to compress the video and audio streams.

That explains why 1 minute of ProRes QuickTime video might be larger than 2GBs but 1 hour of H.264 or HEVC QuickTime video might be smaller than 50MBs. And by converting the codec to H.264 or HEVC, we can easily compress the QuickTime movie file.

In my case, I choose MP4 HEVC for the output format, and the file size of my QuickTime video is shrunk from 9.22GBs to 651.4MBs.

B. Customize Codec Settings to Compress QuickTime Video

Suppose you already have an HEVC or H.264 QuickTime video, then you can hit the Codec option after selecting the target output format. Next, move the quality slider left or adjust the below video properties to compress the QuickTime video file as you like.

  • Decrease frame rate. I shrink the QuickTime video size from 84.6MB to 15.1MB by simply changing the frame rate from 30fps to 23.37fps.
  • Decrease resolution. I have a 326MB 4K HEVC QuickTime video recorded by iPhone. After I downgrade its resolution to 1080P with VideoProc Converter, the size turns to 32.8MB.
  • Decrease the bitrate. Usually, we can set the bitrate as 8000Kbps for HD video and 5000kps for 720P video.
  • Increase the GOP. I don't often use this feature, but it's very useful for compressing those QuickTime videos with few motion changes.

Once you are satisfied with the adjustments, hit Done to go back to the primary panel. And then hit Run to enable VideoProc Converter to start to compress QuickTime video.

C. Compress QuickTime Video by Removing Unwanted Frames

After importing the original QuickTime video to VideoProc Converter, hit the favored video codec. Afterward, you can hit Cut or Crop to remove the redundant clips or frames to compress QuickTime video. Next, hit Run.

How to Compress QuickTime Video Online

PS2PDF is a great piece of browser-based application that lets you compress QuickTime video online without downloading additional software to the computer or mastering any difficult terminologies.

Step 1. Open up this online QuickTime video compressor on your browser.

Step 2. Hit Add Files, and then you can choose Select From Local Disk, Select From Dropbox, or Select From Google Drive to import the QuickTime video file from your local drive, Dropbox, or Google Drive to the app. Depending on the network condition and the file size, PS2PDF might need minutes to hours to load up the file.

Step 3. Come over to the section of Output Quality and File Size. Move the slider left or right to adjust the compression ratio. In my case, I moved the slider to 50 to reduce my file (45.88MB) to half of its original size.

Step 4. Hit Compress Now to compress QuickTime video online with P2SPDF.

However, we'd steer you to VideoProc Converter as the online QuickTime video compressors are for the conversion of small videos only. To take PS2PDF as an example, it doesn't let you compress a QuickTime video with size exceeds 200MB. Ads on the compression page are also quite annoying.

How to Compress QuickTime Video with QuickTime Player

QuickTime player is preinstalled on macOS computers which could be found in the Application folder. It’s not like the most other professional QuickTime video compressors in the market that enables you to fiddle with codec, bitrate, and a few more options to shrink the QuickTime video file size while retaining optimal picture quality. On QuickTime player, you can only compress the QuickTime video by exporting the original file in a lower resolution which will cause horrible quality loss unavoidably.

Step 1. Locate QuickTime player in the Application folder. Click it to open it up on your Mac machine.

Step 2. Come over to the top menu bar. Hit File to find the Import button. Click this to feed the original large QuickTime video file to QuickTime Player.

Step 3. Navigate to the menu bar and choose File again. Choose Export As from the drop-down menu of File.

Step 4. QuickTime player now offers 5 options (4K, 1080P, 720P, 480P, and audio only) for the export resolution. Select the one that is lower than the original resolution to start compressing QuickTime video for free.

Let's say my original QuickTime is in 1080P, then there I can select 720P and 480P as the export resolution.
