How to Compress Video on iPhone and Make the Most of AI Video Tools

Unlock the Potential of Your iPhone Camera

You've probably noticed how today's iPhone camera upgrades rival traditional DSLR cameras, offering creators limitless ways to capture high-quality videos. But what's the downside? These high-quality videos occupy loads of storage space, making it tough to keep them all on your device, not to mention sharing them quickly. If you've been nodding along, you're not alone. Managing storage while keeping video quality intact is a common hurdle creators face.

Luckily, you'll find several methods to compress video on iPhone without losing the video's quality. We'll dive into some simple yet effective techniques to resize your videos, making sharing them a breeze while maintaining that crisp quality you love.

Reduce Video Size While Recording

Want to save space right from the start? You can do this by filming at a lower resolution. This method is about using your iPhone settings to adjust the resolution and frame rate before you hit the record button. Here's how to do it:

  1. Open your iPhone Settings and click on Camera.
  2. Tap on Record Video to view your resolution choices.
  3. Choose a lower resolution, like 720p at 30fps. Apple conveniently notes how much space each resolution requires just below the options.

While this is an efficient way to conserve space without third-party apps, it might not satisfy those seeking cinematic quality. In those cases, compressing your videos post-recording is your go-to solution.

Compress Videos with Apps Post-Recording

If you've filmed a stunning video in high resolution but run into "large file size" errors, don't worry. You can still send those top-notch videos by compressing them after the fact. Although iPhones lack a built-in compression tool, third-party apps like Filmr simplify the process. Here's a quick guide:

  1. Download and install the Filmr app from the App Store.
  2. Open the app, and select the desired video from your Camera Roll.
  3. Once you're in the editing timeline, tap the share icon in the top-right corner to access export options.
  4. Opt to export your video at a lower resolution, such as 480p, then save it back to your gallery.

Share Videos via Email Without Compromising Quality

Perhaps emailing a high-quality video is on your agenda. It's no secret that compressing for email can be a challenge when working with larger files daily. Instead of reducing your video quality, why not share a link after uploading your video to a cloud service? Here are a few ways:

Each of these methods maintains video quality while making it accessible to your team or clients without fuss.

Trim Videos Without Reducing Quality

What if you need to keep every pixel of your project's quality intact and can't lower resolution for compression? There are ways to cut down on file size while maintaining high standards.

You can shorten the video's duration by trimming the less critical portions. Apps like Filmr let you trim and even split the video into parts for seamless sharing.

  1. Download Filmr and open it on your iPhone.
  2. After selecting your video, use the editing timeline to trim unnecessary footage.
  3. Optionally, removing the audio track can further reduce file size without affecting visual quality.
  4. Save your trimmed or split video according to your preferred resolution before sharing.

These tactics ensure you have full control over your project without sacrificing the quality of your work.
