“If I take a video (1366x768 px for me) and put it in a sequence with a higher resolution (1920x1080 px for me) and scale up the video to a higher resolution, it looks blurry/low quality than the original, even after exporting. How to increase video resolution without blurry quality?”

“How can the quality of a low-resolution video be improved? Is it possible to use software or video editing tools to improve the video resolution to HD or at least better than its original quality?”

While boosting video resolution is a great way to achieve a sharper, clearer image, blindly increasing pixel count might result in larger file size only without quality improvements. To truly improve your videos, a strategic approach is necessary. This article will explore effective methods to increase video resolution while maintaining image quality and addressing potential issues.

Increase Video Resolution to HD/4K with High Quality

Winxvideo AI - best AI-powered video resolution enhancer, can easily increase the resolution of videos by 2x, 3x, and 4x to 4K quality. The AI Super Resolution tech ensures the best details and eliminates normal upscaling issues such as pixilated or blurry artifacts. It also lets users to change video resolution from 4K/8K to HD/SD to save space without quality loss.

How Video Resolution Affects the Video Quality?

Video resolution is essentially the number of pixels that make up a single frame. Imagine a video as a canvas composed of tiny dots (pixels). As you increase videos to higher resolutions, you get more dots and thus finer the details. Video resolution is akin to the canvas size, directly influencing the image quality.

Common resolution standards include 720p, 1080p, 2K, and 4K, with each level offering increased pixel count and visual fidelity.

  • Higher resolution: The more pixels, the finer the details. A 1080p video, for example, consists of 1920 pixels horizontally and 1080 pixels vertically, totaling 2,073,600 pixels. In contrast, a 4K video boasts over 8 million pixels, providing significantly more detail.
  • Lower resolution: with less pixels, when displayed on a larger screen, the pixels become stretched to fill the available space. For example, as you magnify an image, the individual pixels become visible, creating a blocky or grainy effect. The same principle applies to videos when displayed on larger screens.

When Do You Need to Increase Video Resolution?

Increasing video resolution is essential when:

  • Creating content for large displays: Whether it's a TV, digital billboard, or cinema screen, higher resolutions offer a significantly improved viewing experience, preventing pixelation and enhancing detail.
  • Professional Projects: Film, television, and commercials often require high-resolution footage for editing flexibility, visual effects, and overall production quality.
  • Future-proofing purpose: Increasing older, lower-resolution videos to higher resolutions can help accommodate emerging display technologies and provide longevity to your content.
  • Post-Production: Activities like cropping, zooming, color grading, or adding visual effects benefit from improved video resolutions.

How to Increase Video Resolution with Best Quality?

Below we will share detailed steps on how to increase video resolution with AI tools, online tools, and professional editors.

3. Vmake AI

Online tools offer convenient solutions for enhancing video resolution. If you only need to increase the resolution of a few videos, online video enhancers are worth considering. Many online tools provide free or affordable options, making them accessible to a broader audience. For instance, Vmake AI Video Enhancer is one such tool that can improve video resolution.

Vmake AI is an online platform that utilizes AI to improve video quality. It offers features like upscaling, noise reduction, and color correction. While it promises to enhance videos up to 4K resolution, actual output often maxes out at 2K. The platform automates several adjustments, including brightness, contrast, and saturation, but lacks granular control over the enhancement process.

While Vmake AI provides a convenient solution for quick video resolution improvements, users should be aware of its limitations. For example, it lacks control over the enhancement process, meaning you can't choose the specific resolution you want.

Steps to Increase Video Resolution Online

Is Higher Resolution Always Good?

While higher resolution often correlates with improved image quality, it's essential to consider the broader picture. Several factors influence the overall viewing experience:

  • Storage and Processing Demands: High-resolution videos require substantial storage space and powerful hardware for editing and playback.
  • Bandwidth Constraints: Streaming high-resolution content demands high-speed internet connections, which might not be universally available.
  • Diminishing Returns: Beyond a certain point, the human eye may not perceive significant differences between extremely high resolutions.
  • Content Suitability: Some content, like talking heads or simple animations, might not benefit significantly from ultra-high resolutions.

Increasing the resolution of a low-quality video to a higher resolution can introduce artifacts such as pixelation or blur. When upscaling, avoid selecting an excessively high resolution, as it may only increase file size without improving quality. It's important to note that resolution and image quality are not equivalent concepts.

Advanced techniques like deep learning and neural networks can enhance image quality by mapping low-resolution images to higher-quality versions. These methods aim to improve visual quality by enhancing details and reducing noise. By leveraging these technologies, it's possible to generate higher resolution images with superior visual quality.

Conclusion

Increasing video resolution using AI enhancers and online tools are the two easiest ways. For more advanced users, you can also try professional video editors, such as Premiere Pro and DaVinci Resolve. AI-based upscaling is particularly useful for older videos or content while enhancing details, reducing noise, and making the content more suitable for larger screens. For occasional use, online resolution enhancers provide a quick and easy solution.

However, it’s important to consider that upscaling may introduce artifacts if pushed too far and can lead to unnecessarily large file sizes without actual quality gains. Therefore, increase the resolution when the original content is of decent quality or when required for specific purposes like presentations or professional use. Avoid upscaling when the video’s original quality is very low or when the added resolution doesn't provide a meaningful improvement in viewing experience.
