Quick Answer
Video plays a huge role in our daily entertainment. Many users watch different clips for information, fun, and memories. But have you ever opened an old video file, clicked play, and felt that sinking feeling? The edges are blurry, faces look like pixelated blocks, and the poor quality ruins the moment on your modern screen. You are not alone. But can you fix the blurry video and make it look sharp and clean? Surely, you can. In this guide, we gather the 3 ways to increase video resolution with AI through desktop software, online tools, and mobile apps, so that you can turn your old 360p, 480p, and 720p footage into 1080p, 4K, or 8K instantly.

Think of a video like a mosaic made of tiny colored dots called pixels. The more dots you have, the clearer the picture looks. Can you increase 240p to 1080p? Yes, and looking at the pixel counts helps you see why it matters.
If a video has very few pixels, it looks blocky when you stretch it out on a big monitor. Let's look at a quick chart to see how these sizes compare.
| Resolution (Width × Height) | Total Pixels | Common Term | Typical Screen | Size vs 1080p | |
|---|---|---|---|---|---|
| 240p | 426 × 240 | ≈0.10 M | Low SD | Old phones | 0.05× |
| 360p | 640 × 360 | ≈0.23 M | SD | YouTube low quality | 0.11× |
| 480p | 854 × 480 | ≈0.41 M | Standard SD | Old DVDs | 0.20× |
| 720p | 1280 × 720 | ≈0.92 M | HD | Laptops, basic streams | 0.44× |
| 1080p | 1920 × 1080 | ≈2.07 M | Full HD | Monitors, TV | 1× |
| 2K | 2560 × 1440 | ≈3.69 M | QHD | Gaming screens | 1.78× |
| 4K UHD | 3840 × 2160 | ≈8.29 M | 4K | Modern TVs, editing | 4.0× |
| 8K UHD | 7680 × 4320 | ≈33.18 M | 8K | Giant screens | 16× |
Old video editors used a basic trick called stretching. If you had a tiny video, the software just copied neighboring pixels to make it fit a bigger screen. What did you get? A blurry, washed-out mess.
An AI video upscaler works differently through super resolution. It looks at thousands of clear images. It learns what textures, edges, and faces should look like. When you feed it a blurry video, the AI actually guesses and builds brand-new pixels that make sense. It doesn't magically create real details that were never filmed, but it makes the video look clean and crisp instead of blocky.
If you want the best results for a desktop computer, AnyMP4 Video Converter Ultimate is my top pick. It is a powerful desktop program that gives you two different ways to increase video resolution depending on what you need. Let's look at both features!
If you have a blurry old video and want true AI reconstruction, use the built-in enhancer tool. When I tested AnyMP4 Video Converter Ultimate on my test PC, I found this feature very fast and straightforward to set up:
1. Free download and install AnyMP4 Video Converter Ultimate via its web page for free.

Open the software and click the Toolbox tab at the top of the main screen. Look for the Video Enhancer tool icon and click it.
2. Click the big plus (+) icon in the middle to pick your blurry video file, then click Open.
3. Check the box that says Upscale Resolution. Then go to the bottom menu, open the Resolution drop-down list, and pick 1080p, 4K, or 8K.
Click the Preview button to see a quick sample. If it looks good to you, click the Enhance button and wait for the export to finish.
If you just want a standard conversion and want to adjust the output resolution quickly while converting formats, you can use the main converter tab:
1. Open AnyMP4 Video Converter Ultimate and stay on the default Converter tab.

Click the Add Files button in the upper left corner to load your video.
2. If you want to increase a video file resolution, just click the custom settings on the right side of your video list to upscale the video resolution to 1080p, 4K, even 5K/8K.
If you have multiple video files that need to improve the video resolution, just find the custom profile setting icon at the bottom-left side to open the Resolution drop-down menu in the settings window and choose your target size like 1080p or 4K.
3. Save the settings, choose an output folder at the bottom, and click the Convert All button to process your video files.
Do not forget to enable your GPU acceleration on the top-right corner to make the conversion process 70 times faster than other tools.
In this method, you can easily improve and change video resolution.
When you increase video resolution, your file size will jump up fast. More pixels mean more data. Here is a handy guide so you know how much hard drive space you will need, including the exact 4K file size per minute breakdown.
| Resolution | Recommended Bitrate (H.264) | Size per Minute (Approx.) | 10 Minutes (Approx.) | 1 Hour (Approx.) |
|---|---|---|---|---|
| 480p | 1.5 - 2.5 Mbps | 11 - 19 MB | 113 - 188 MB | 0.7 - 1.1 GB |
| 720p | 2.5 - 5 Mbps | 19 - 38 MB | 188 - 375 MB | 1.1 - 2.2 GB |
| 1080p | 5 - 8 Mbps | 38 - 60 MB | 375 - 600 MB | 2.2 - 3.6 GB |
| 1440p (2K) | 10 - 16 Mbps | 75 - 120 MB | 750 MB - 1.2 GB | 4.5 - 7.2 GB |
| 4K UHD | 20 - 45 Mbps | 150 - 338 MB | 1.5 - 3.4 GB | 9 - 20 GB |
| 8K UHD | 80 - 150 Mbps | 600 MB - 1.1 GB | 6 - 11 GB | 36 - 66 GB |

We understand that not everyone has access to a computer. Many of us use mobile devices like iOS and Android. Therefore, in this part, we will look at how do i increase video quality on Android and iOS devices with a video resolution converter app.
InShot is a popular mobile video editor available on iOS and Android that lets you trim, edit, and adjust export resolutions easily on the go. When I tried InShot on my phone to polish a quick clip, I found the export menu very clear. Here is how to use it:
1. Install InShot from your phone's app store and open the application. Tap Video and pick the clip from your gallery.
2. Look at the top right corner of the editing screen and tap the export or resolution tab.
3. Choose a higher resolution like 1080p, 2K or 4K from the drop-down list, and tap Save.
Very easy, right?
Let's compare the two main ways to change video sizes so you know what to expect.
| Traditional Stretching (Bicubic) | VS | AI Super-Resolution |
| Math formulas copy neighbor pixels | How it works | AI network rebuilds missing textures |
| Soft and blurry edges | Sharpness | Clean and sharp lines |
| No (makes things flat) | Detail recovery | Adds realistic guessed detail |
| Very fast (instant) | Speed | Slower (depends on your graphics card) |
| Quick drafts or small screens | Best used for | Old home videos, 1080p to 4K projects |
What is the recommended video resolution for mobile playback?
The recommended video resolution with your mobile playback is 1280 × 720. In addition, the suggested aspect ratio for landscape is 16:9 and 1:1 for squares. For portraits, you may set 9:16.
Why is increasing video resolution necessary?
The importance of increasing the quality of our video is to get a much clearer picture of the video. This element is a great way to bring us more immersive moments of watching our videos.
Does upscaling reduce quality?
It cannot pull back real details that were never filmed. Traditional stretching makes images blurry, while AI upscaling builds clean synthetic details.
How much bigger is a 4K file than 1080p?
4K UHD has about four times the pixels of 1080p. Because of that, the 4K file size per minute is usually about four times larger, taking roughly 150 to 338 MB per minute. Check this guide to learn how to upscale 1080p to 4K.
Do I need a powerful GPU to upscale video?
Not for basic resizing, but AI upscaling runs much faster if your computer has a dedicated graphics card (GPU).
What is the difference between 1080p and 4K?
1080p has about 2.07 million pixels, while 4K has about 8.29 million pixels. You notice the biggest difference on screens that are 55 inches or larger.
Is 8K worth it?
Usually no for everyday viewing. 8K files are massive and most screens cannot show the difference over 4K. Save 8K for special displays or professional archives.
In this article, we can see the 3 instant and practical ways we can follow to increase the resolution of our video like desktop software, online tools, and mobile applications. Make sure to follow every step to transform your low-quality video like 360p into at least 720p or 1080p. We are hoping that this article will help you with your task.
