As video content and film creators, it’s essential to understand the upscaling process and how it can enhance your work. Upscaling is the process of enlarging an image or video’s resolution, providing a way better look when viewed on high-definition screens.
In this article, we will look at the benefits of upscaling, such as improved image quality and compatibility with modern devices.
We’ll also explore various techniques for upscaling that you can apply in your projects. Last, we’ll introduce some popular AI upscaling tools designed specifically for this purpose. Let’s start by defining what is upscaling?
What is Upscaling?
Upscaling, also referred to as resolution scaling or image scaling, is the process of increasing the resolution of digital images or videos while preserving their original aspect ratio (for example, upscaling a video from 480p to 720p or 1080p.).
An upscaling software program will add new pixels and interpolate (estimate) their color values based on surrounding pixels.
The results are higher-resolution versions of the original lower resolution images or videos that appear sharper and more detailed. This can help blurry images and low-quality videos look amazing on your playback device!
The Difference Between Native Resolution and Upscaled Content
Native resolution: For example, Full HD content has a native resolution of 1920×1080 pixels and 4K Ultra HD footage is captured with 3840×2160 pixel count (as opposed to film industry 4K, which is 4096×2160 pixels).
When you capture footage at these resolutions using a camera with corresponding sensor capabilities, no additional processing is required because each pixel has been captured natively by the device.
Upscaled content: On the other hand, when you upscale lower-resolution footage (e.g., from SD to HD), you are essentially creating artificial detail by estimating what additional pixels should look like based on neighboring information within an image frame.
While this is not as accurate as native high-resolution capture methods (due to interpolation algorithm errors inherent in the estimation processes), this upscaling process produces a higher resolution video that can look great on an HD television, 4k TV or Blu Ray player.
How Does Upscaling Work?
Upscaling works by taking all the available pixels of a video or image and interpolating them to create new, higher resolution pixels. This interpolation process can be done in two ways: software-based algorithms or hardware-based algorithms.
Software-based algorithms are typically used for upscaling videos on computers and other devices. These algorithms use sophisticated algorithms to interpolate the existing pixels and create higher resolution pixels. Software programs that allow you to upscale images and videos on the computer include Topaz AI and AVCLabs.
Hardware-based algorithms, on the other hand, are typically used for upscaling videos on TVs, Blu Ray players and other displays. These algorithms are more advanced and use more sophisticated interpolation techniques to create more detailed and accurate images.
Benefits of Upscaling For Images & Video
Upscaling can have a number of benefits for video creators and filmmakers, as delivering high-quality visuals is crucial for standing out from the crowd. Here are some reasons why upscaling matters:
Better viewing experience: Higher-resolution content offers a more immersive visual experience on larger screens or devices with higher pixel density displays.
Improved video quality: Upscaling can help improve the quality of low-resolution videos by increasing the resolution and adding more detail and clarity. This can make videos look better on larger displays and can help improve the overall look and feel of your videos.
Increased file size: Upscaling can also increase the file size of your videos. This can be beneficial for video creators who are looking to upload their videos to higher resolution platforms or websites, as larger files will typically look better than smaller files.
Improved compatibility: Upscaling can also help improve the compatibility of your videos with different devices and platforms. By increasing the resolution of your videos, you can ensure that they will look better on a wider range of devices and platforms.
Mixing different resolutions: When working with footage captured at various resolutions (e.g., combining archival SD clips with modern HD/4K recordings), upscaling lower-resolution material helps create a consistent look across the entire project.
Future-proofing your work: As display technology continues to evolve rapidly (with 8K TVs already available), ensuring that your content looks great on these cutting-edge platforms can help maintain its relevance over time.
Creative Flexibility: Finally, upscaling provides greater creative flexibility when it comes to editing and post-production work. For example, if you need to crop or reframe certain shots during the editing process without losing quality, working with upscaled footage makes this much easier since there are more pixels available within each frame.
Tips for Upscaling
If you’re looking to get the most out of your upscaling process, here are some tips to keep in mind:
Choose the Right Resolution
Select an appropriate resolution that meets your project needs and audience preferences, such as 1080p or 4K for online streaming services like YouTube. For instance, if you’re creating content for online streaming platforms like YouTube, consider upscaling to 1080p or even 4K resolution for optimal viewing experience.
Choose the right upscaling algorithm
Depending on the device or platform you’re using, you should choose the right video upscaling algorithm. Software-based algorithms are typically used for computers and other devices, while hardware-based algorithms are typically used for TVs and other displays.
Choose the right technique
Depending on your project’s requirements, select an upscaling method that offers a balance between output quality and processing time.
Use a high quality source video
Video upscaling will only work if you start with a high quality source video. Always try using high-quality footage as much as possible – whether shot by yourself or obtained from stock libraries such as Shutterstock or Artgrid.
Maintain aspect ratio
When upscaling videos, always ensure you maintain the original aspect ratio to avoid distortion or stretching of the content.
Incorporate noise reduction
If your source material contains noise or graininess, consider using noise reduction tools before applying any upscale technique to achieve better results.
Test the upscaled video
Once you’ve upscaled the video, it’s important to test the video to make sure it looks the way you want it to. This will help you ensure that the upscaled video looks as good as possible.
Adjust settings as needed
Depending on the device or platform you’re using, you may need to adjust the settings of the video upscaling process. For example, some platforms may require specific settings for the process, so it’s important to adjust the settings as needed.
Avoid excessive upscaling
Keep in mind that there is a limit to how much detail can be added to your lower resolution video. Overdoing it may result in artifacts or unnatural-looking images.

Common Questions About Upscaling
What is the purpose of upscaling?
Up-scaling is a process of enhancing the quality of an image or video frame by increasing the resolution. This technique is used widely in various areas, such as film industry, video games, and electronics like televisions and smartphones, resulting in an improved viewing experience.
Does upscaling improve picture quality?
Upscaling may not truly improve the picture quality of a TV, as it cannot create additional image detail. However, it can reduce visual noise and sharpen edges to deliver sharper, clearer images on larger displays. The effectiveness of the upscaling process depends on the quality of the upscaler, the size and quality of the original image, and the viewing distance.
Does upscaling increase resolution?
Yes, upscaling increases the resolution of an image or video by creating additional pixels using interpolation algorithms. The result is a larger file with more detail and better overall clarity than its original low-resolution counterpart.
Does upscaling lose quality?
While upscaling can improve an image’s appearance at higher resolutions, it may not always maintain perfect quality due to limitations in interpolation algorithms. However, advanced techniques and tools have significantly reduced these issues for better-upscaled results.
