As technology evolves, 8K is emerging as the future of video. With unmatched sharpness, it enhances gaming, digital signs, and precise surgical visuals. More people want better content and clearer pictures, so 8K is becoming popular with everyone.
Let’s review the important data to grasp the value of 8K around the world.
8K is not just a resolution upgrade—it's a transformative leap in how we experience video content. As 8K adoption grows, AI video upscaler is becoming essential to enhance lower-resolution content for these ultra-high-definition displays.
Key contributors driving the growth of the global AI video upscaling software market include:
Other key statistics are:
For some users, 4K is the benchmark. However, others using modern devices may not be content with the 4K resolution. Upscaling 4K to 8K helps make the picture sharper and viewing more enjoyable. Before diving into why we upscale 4K to 8K, let’s get clear on what both are.
Additionally, we’ll unveil how AI technology can be leveraged to enhance the precision and accuracy of the results.
4K refers to a 3840 x 2160 resolution in consumer marketing. It means 3840 horizontal pixels and 2160 vertical pixels. Here, resolution is synonymous with the number of pixels per inch. A 2160p display will display more detail than a 720p display. 720p is high definition (HD), 1080p is full high definition (FHD), 1440p is quad high definition (QHD). It has four times the pixels of 720p, and anything above 2160p is considered Ultra High Definition (UHD).
On the contrary, 8K means the screen has 7680 pixels across and 4320 pixels down, offering four times the clarity of 4K and sixteen times that of Full HD. It delivers crystal-clear images, making it perfect for large TVs, immersive games, content creation, and medical scans.
8K is renowned for sharper and more detailed images. It provides a clearer and sharper view, perfect for large TVs and displays. Additionally, whether you have low-resolution video or 4K, upscaling it to 8K makes it future-proof for modern screens.
Beyond clarity, there are several reasons to support 4K to 8K upscaling. Here are a few of them.
| Reasons | Description |
| Enhance Image Detail | Provides four times the 4K px for a detailed and sharper image |
| Future Proof Content | Looks excellent on future-generation, high-tech devices |
| Improved Viewing Experience | Maintains picture clarity, preventing pixelation on large home theatres |
| Fix Older Footage | Improves the appearance of older HD and 4K footage by adding clarity and fine detail |
| Better Editing Flexibility | Flexibility for zooming and cropping in post-production without losing quality |
| Efficiency Streaming | Seamless streaming on digital services like YouTube, etc. |
Previously, traditional upscaling was employed. It worked fine, only until AI upscaling was introduced. Standard measures took an immense amount of time, only to generate average results. They lacked accuracy, precision, and fine-tuned details. However, AI upscaling technology studies large amounts of data to add details that fit the content.
Here’s a short look at how they differ.
| Factors | AI Upscaling | Standard Upscaling |
| Techniques Used | Neural networks trained on large datasets (low-res to high-res pairs) | Bilinear, Bicubic (fast), Lanczos (better quality but slower) |
| Pixel Count | Large context area using patterns learned from vast image/video data | Small context area, limited surrounding pixels considered |
| Output Quality | High-quality, sharp edges, finer details, and more natural results | Moderate; edges may appear blurry or soft |
| Scalability Over Time | Dynamic; improves as the AI model is trained with more data | Static; does not improve |
| Use Cases | Ideal for 4K/8K video, gaming, film, and restoration | Basic upscaling needs |

Upscale Video from 4K to 8K with a Single Click!
The most notable aspect of this AI video upscaler was its unique AI-based models. Let’s have a look at each one of them. And thereafter, we’ll explore each AI model through our lens.
| AI Models | Description |
| Texture Enhanced Model | Improves texture and fine-tunes details |
| Speed Optimized Model | Rapid upscaling while balancing quality |
| Quality Optimized Model | Maximizes the sharpness and clarity of the frames |
| Anime Optimized Model | Preserves sharp lines but adds vibrant colors |
We have tested each AI model individually to understand its operations. And see whether it lives up to its name and description. Here’s how our experience went with each one.
The Texture Enhanced Model specializes in improving texture and detailed elements. It identifies all the elements in individual frames and makes them appear natural without hassle.
Our Experience with Upscaling from 4K to 8K:
To test the Texture Enhanced model, we used a short 1-minute 12-second podcast clip in 4K quality. Our clip’s frames were processed by this model, which enhanced the textures of surfaces like skin, fabric, and scenery. They appeared more dense and natural with sharper edges.
UniFab didn’t add artificial noise or jittery artifacts. Instead, it worked by recognizing texture patterns and structures to produce a more natural result. We then tested the model using nature footage and a few close-up shots. To our surprise, the results were consistent - stunning!
In a nutshell, this model elevates every element crisply. It makes it feel more realistic. We received our 8K results, which are loud with depth and realism.
As you know, speed is a game-changer for most creators. Completing the most work in the shortest time is vital for thriving in today’s digital world. Here’s where the Speed Optimized Model kicks in to accelerate your productivity without compromising quality.
Our Experience with Upscaling from 4K to 8K:
Next, we had to test the Speed Optimized model. We didn’t take anything lengthy to test its speed; instead, we used the same clip used earlier. However, we didn’t test the videos one at a time; we processed them all as a batch this time.
To our surprise, UniFab delivered smooth upscaling at impressive speeds. The total length of all the videos was approximately 5 minutes. And UniFab took roughly 50-60 seconds to process all the clips. Undoubtedly, it is ideal for real-time applications and, of course, bulk processing.
But to us, speed alone wasn’t the only challenge. After all, we were testing it to upscale 4K to 8K.
To be honest, the sharpness was visible, but it wasn’t close to the Texture Enhanced Model. However, it did balance speed with visual clarity exceptionally well.
Overall, when you are working on tight deadlines or need to test different outputs like us quickly, the Speed Optimized Model can be the ultimate solution. The quality was definitely not bad. It’s just that we had a comparative angle after testing the first model. For new users, testing this model alone, the results are efficient and reliable. It lets you work quickly without sacrificing much in terms of quality.
When overall video quality is your top priority, the Quality Optimized Model can help you achieve your goals. Ideally, it was introduced to maximize video sharpness and produce accurate, vibrant colors. It focuses on overall image clarity.
Our Experience with Upscaling from 4K to 8K:
Next, we tested the Quality Optimized Model. Again, to maintain consistency, we took the same video clips as before. Undoubtedly, the generated results were stunning! Absolutely flawless! Almost as if you are living in the frames.
When played on large 8K screens, we were truly mesmerized by the overall quality. It not only enhanced each frame but also preserved the integrity of the original scenes. Each element stood out and spoke for itself. It was truly a magical 8K experience.
However, the processing time was a bit longer. Like not much, but longer when compared to the Speed Optimized Model. Again, the processing time might have been normal considering the quality, color accuracy, and sharpness of the overall frame. However, since we had previously worked on the Speed Optimized Model, the comparative angle automatically came into play.
Maybe new users won’t find the processing long if they work with this model alone.
For the ardent anime fans, the Anime Optimized Model is the best pick. It intelligently detects and analyzes the anime frames to handle the sharp lines and add bold colors. Whether you have 2D style content or anime, this model precisely preserves the outlines and vibrant tones without distortion.
Our Experience with Upscaling from 4K to 8K:
Finally, we had the Anime Optimized Model. To test its performance, we opted for a short 4K cartoon clip. While my clip had everything needed for an enriching viewing experience, we didn’t expect much from this model.
However, the results proved us wrong. When put in comparison (Before and after), the changes were clearly visible. Not only did it keep everything clean and stylized, but it also worked on blurry edges to fix them. The colors weren’t washed out. It gave due respect to the original aesthetics during 4K to 8K upscaling. The clarity was noticeably enhanced. To be honest, it appeared as if the cartoon was actually drawn in 8K itself.
Talking about the speed, it didn’t take much time to process. The wait time was far better compared to other AI anime upscalers we have worked with in the past.
Overall, it is the perfect pick for creators working with animation films, shows, and motion graphics.
If these models pique your interest, you must not shy away from testing one while inducing 4K to 8K upscaling.
