We have all been there: you find an old family video, an early smartphone clip, or a low-res download, and you want to watch it on your modern screen. But when you scale it up, it instantly turns into a blurry, pixelated mess of macroblocks and muddy details.
Increasing video resolution isn't just about stretching the frame and adding more pixels. If you do that, you just get a larger, blurry video. True video enhancement means using intelligent software to analyze what is in the frame and accurately rebuild the missing details.
Here is a straightforward guide on how to 提高视频分辨率 to crisp 1080p or 4K with online and desktop tools. You will know the key factors to enhance video with the detailed guides below.
Part 1. Why Is Video Upscaling Important?
Most modern displays and monitors boast a resolution of 1080p or higher. If your video is stuck at 720p or lower, it will inevitably look blurry and pixelated on these screens. To deliver a crisp viewing experience, it is essential to ensure your video resolution aligns with the standards of today's devices.
Part 2. Does Increasing Video Resolution Also Increase Quality?
No, just increasing the resolution doesn't mean that your video gets higher quality. In video technology, discussing resolution without mentioning bitrate is like talking about how big a box is without checking what's inside.
Resolution is the Frame, and Bitrate is the Flesh: Resolution (1920:1080 or 3840 :2160) merely defines the grid of pixels. Bitrate (the amount of data processed per second, measured in Mbps) determines how much actual, rich visual information fills those pixels.
Therefore, the methods we are going to show you below will also help you increase the bitrate to truly increase the video quality.
Part 3. How to Increase Video Resolution Without Losing Quality
AVAide 视频转换 is your go-to desktop software for ultimate video enhancement. While it offers extensive resolution options ranging from standard definition to a stunning 4096x2160, it does much more than just increase the video resolution. By allowing you to increase the video bitrate, AVAide fundamentally optimizes the data density, allowing you to bump up the resolution while simultaneously elevating the actual image quality. This guarantees a sharper, crisper, and lossless output. Moreover, it has an AI video enhancement feature to correct the video color and remove video noise, which will finally improve your video from all aspects.

Steps to Increase Video Resolution and Quality
第1步Add Your Videos to AVAide Video Converter
下载、安装并启动 AVAide 视频转换. Click the Add Files button in the top left side to import your videos.
第2步Choose a High Quality Preset
点击 输出格式 dropdown button on the bottom left. Then, you should choose a desired video format, like MP4. Then, choose a preset with your desired resolution, like 4K视频.
What's important is coming: 点击 自定义配置文件 button (with a Gear icon) in the preset bar.
第 3 步Adjust the Bitrate
On the new panel, you can select 高质量 to use the default high-quality preset. You can also select 定制 并点击 比特率 dropdown button to select 4000kbps to highly increase the video quality. Then, click the 创建新的 按钮。
- Maybe you’ll wonder why AVAide Video Converter doesn’t provide a higher bitrate? That’s because if the bitrate is set too high, though the video quality is getting higher, the compatibility will decrease. Many devices cannot recognize those too-high-bitrate videos. Therefore, 4000 kbps is the best and most recommended value.
第四步Save Your Videos
最后，您可以点击 存到 dropdown button to select a file folder for your upscaled video. Then, just click the 全部转换 button to increase the video resolution and bitrate to truly 提高视频质量.
- 优点
- The interface is simple and easy to use.
- Let you adjust the video bitrate, which is crucial for video quality.
- Provide H.265 video codec to reduce file sizes while keeping high quality.
- 缺点
- There's no AI editor option in this program.

Part 5. FAQs of Increasing Video Resolution
What is the best app to increase video resolution?
Remini is a good solution to increase video quality on Android and iPhone. If your video features people or faces, Remini is widely considered the absolute gold standard. Its AI models are deeply trained specifically on facial reconstruction, allowing the app to intelligently recreate sharp skin textures, eyelashes, and hair strands from blurry, out-of-focus, or low-resolution footage, delivering a stunning high-definition output instantly.
Can poor quality video be improved?
Yes, but there are limitations. Adjusting resolution, bitrate, color, contrast, and many other settings can increase simple, poor-quality videos. But if a video has too low a quality, like sub-480p with heavy compression artifacts, it cannot be improved.
Why is my 1080p video blurry?
1080p doesn't mean the video quality is also high. You'd better find the source video and upscale it while increasing the video bitrate. AVAide 视频转换 is a reliable program that can easily do the above.
This article offers 2 ways to increase video quality online and on Windows or Mac. Topaz is a good choice to increase video resolution with AI models. However, it cannot increase the video bitrate. That is not a significant drawback. AVAide 视频转换 can help you increase video bitrate up to 4000kbps while increasing the video resolution to 1080p, 2K, 4K, and even 8K. That can fully enhance the video quality.
