Part 1. Why You Need to Compress a Video on iPhone

For a variety of everyday reasons iPhone users run across, video compression becomes essential. While producing gorgeous visual content, contemporary iPhones capture 4K resolution high-quality videos that result in big file sizes that can easily fill your device's memory. One of the main reasons for video compression is storage management.

One minute of 4K video might use up from 375MB to 400MB of storage, so a ten-minute film might consume almost 4GB. This storage use might become difficult fast for those using iPhones with 64GB or 128GB. Necessity for video compression is also fueled by sharing and communication requirements. While messenger services such WhatsApp limit video files to 16MB, email providers usually cap attachment sizes to 25MB or less.

Although social media sites have their own compression algorithms, uploading smaller files provides quicker upload speeds and improved user experience.

Part 2. How to Compress iPhone Videos Before Recording

Camera Settings Reducing Video Resolution

The most efficient approach to control video file sizes is to modify your recording settings prior to commencing filming. While still preserving great video quality for most uses, this forward-looking strategy removes post-recording compression necessity.

Adjust the video recording settings of your iPhone by:

• 1.Open the Settings app on your iPhone.
• 2.Scroll down and tap on Camera.
• 3.Choose Record Video
• 4.Select from the following resolutions and frame rates:
  • 30 fps, 720p HD (least file size)
  • 30 frames per second in 1080p HD: balanced size and quality
  • Superior quality and a bigger file are 1080p HD at 60 fps.
  • Highest quality, largest file: 4K at 24/30/60 fps.

1080p HD at 30 frames per second offers a great equilibrium of video quality and file size for most routine recording needs. While maintaining reasonable file sizes, this configuration enables most devices to show videos that are excellent.

You can also change the Record Slo-mo settings in the same menu to manage the file sizes of slow-motion videos, which have rather big frame rates.
