Edited by Ava Wilson Aug 12, 2025 Enhance Video

The iPhone has long been celebrated for capturing high-quality videos. It offers sharp resolution, vibrant colors, and smooth frame rates, especially on the latest models. With features like 4K recording, it's no surprise that many rely on their iPhones for videography. However, not all iPhones support high-resolution recording. Older models lack the hardware needed to record 4K videos. That being said, it leaves users with low-resolution footage that appears blurry. This leads many iPhone users to ask: How to upscale videos on iPhone? This post will show you the right way to upscale videos directly on your iPhone. Additionally, for those with older iPhone models, we'll introduce an alternative that can help you enhance videos.

Part 1. What it Means to Upscale a Video

Newer iPhone models come with high-resolution displays, surpassing older iPhones' video quality. With that being said, many are seeking ways to upscale videos to 4K directly on their devices. This is where video upscaling takes a hand.

In simple terms, upscaling a video means increasing its resolution. This process makes the video appear clearer and more suitable for higher-definition displays, like those found on the latest iPhones. To explain it further, it works by adding new pixels to the original video using advanced algorithms, predicting what the missing details might look like.

Think of it this way: Upscaling a 480p video can be converted into 1080p or higher. This makes the video look less blurry and more refined when played back. But does upscaling a video increase its video quality? Technically, it enhances perceived quality rather than truly increasing it. That's because the process doesn't create real details that weren't captured in the original footage. It only approximates them.

Part 2. How to Upscale Video on Your iPhone

By default, the resolution of iPhone video is 4K at 30 frames per second. Still, depending on your device's model and iOS version, you can configure the resolution settings. However, you should be aware that higher resolutions and faster frame rates can result in larger video files.

Use Quick Toggles to Change Resolution and Frame Rate

iPhone's Video mode offers quick toggles to instantly switch between video resolutions and frame rates. You can choose HD or 4K and select frame rates such as 24, 30, or 60 fps. Setting the resolution to 4K and frames per second to 60 produces clearer, smoother videos.

Here's how to enhance video quality on iPhone:

Step 1. Open the Camera app and swipe the screen to the right to switch to the Video mode. In Video mode, tap the HD button to change the video resolution settings. This action will let you access the video recording settings on your iPhone.

Step 2. In the Record Video settings, you'll find several video resolution and frames per second options. It includes 720p at 30 fps, 1080p at 30 fps, 1080p at 60 fps, 4K at 24 fps, 4K at 30 fps, and 4K at 60 fps. For best image quality, select 4K at 24 fps. This option can provide a cinematic look for those who prioritize low-light performance.

Important Note: Stick to 1080p at 30 fps for most of your video shooting if you prefer natural motion blur. Go with 4K at 60 fps if you want to capture super crisp videos. However, please be informed that this option can make the video look a bit unnatural.
