- When editing my video, I’d like to zoom in on my friend’s face and make it so he also isn’t blurry. Along with this, I’d like to make sure the entire video isn’t blurry too.

- I wanted to zoom in about 150% but the resulting file is slightly blurry? Even when I make a DVD the footage is blurry. Don’t know how to fix it.

Over-scaling leads to a pixelated videoOver-scaling leads to a pixelated video

A few users complaining about when they are editing their videos, their videos blew up after zooming in, which means you see the frames consisted of many small cells instead of smooth pictures.

How to remove the annoying blurriness in Adobe playback? The first step is to find out where the problems came from. Blurry videos could be caused by many reasons and this post is going to unveil some of them for you.

Why footage get blurry after scaling it in Adobe Premiere Pro CC — reasons and solutions

  • Possible reason 1: The resolution of your source videos is too low. You have to figure out what recorder you used to film your footages. If you recorded videos hold rather poor resolution in the first place, the video will easily blow up once edited with scaling.
  • Possible reason 2: Video is clean enough, but your monitor cannot support that high. More and more ultra-high-definition video materials are available online. However, if your PC display is still the old one, you hardly tell the differences from 1080p and 4K, the worse is that you may see jagged edges on videos.
  • Possible reason 3: There are two terms you need to know in this part, raster graphics and vector graphics. Raster graphic, also referred to bitmap, uses countless color dots (pixels) to create an image. In normal conditions, people hardly notice those small squares that combine a picture, but they will appear when an image be enlarged out of boundaries. On the contrary, vector graphic forms a picture by lines, points, curves, and other shapes. Resolution independent is its edge, which is a signal that video in this file can be scaled to any size without quality loss.
    Since vector-based files have that benefit, why we don’t apply to the whole media industry? Because there is no codec can manage this mission.
    However, the University of Bath has released a paper about a new vector-based video codec in 2012, claiming that it will lead to the death of pixel soon. But there is a flaw existing in the codec that the area between colors cannot be perfectly filled at high resolution. This can cause the animation on any image and video, that’s the reason why it cannot replace raster graphics at present.
  • Possible reason 4: Adobe Premiere Pro CC stated that not all video file formats are available in the program, and there will be playback issues covering flickering videos, or video occurs blurry, fuzzy, pixelated and other worse, if imported video files formats are not compatible.

And the solutions are as follows.

Solution 1: Purchase professional devices and employ vector-based videos

The purchase of a professional recorder and a high-definition monitor can be a good option. A well-qualified recorder guarantees high resolution of your raw videos, while a top display enables you to watch videos with high enough resolution. And here are some tips for you on how to pick up recorder and monitor. If you want an all-around and high-quality recorder, take a full-sized camcorder into account. If you want a recorder which is easy to take, go for an action cam. As for the monitor, 4K display with 28 inches is trending now, which allows you to deal with various kinds of footages and also can protect your vision at a certain point.

Assure that your source videos are vector-based. Given that fact that vector graphic forms a picture by lines, points, and other shapes instead of rectangular pixels. And it features as resolution-independent, allowing you to scale footages at any size without quality loss.

Solution 2: Download required codec or remove unwanted codec

Download a required codec. Generally speaking, editing a video file requires more things on technical than playing a video. Some codecs like DivX, 3ivx are not installed with Windows and Mac by default, so you need to download required one from qualified publishers for playing or editing video.

Remove the codec causing conflicts. If you have problems with importing video, that could cause by poorly designed codec or one video format employing multiple codecs. To address the playback issue, remove or disable third-party codecs from the control panel. And here the guide to disable codecs.

  • Step 1: Call out the box by pressing “Windows” and “R” simultaneously.
  • Step 2: Type “regedit” in the box and click OK.
  • Step 3: Find out the unwanted codec following this file path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32.
  • Step 4: Double click or right click to disable or remove the unwanted codec.

Solution 3: Adjust parameters or transcode the file to a compatible format

Record your video as high resolution as possible and edit at low resolution. For example, your video resolution is 1080p high, but your edit it at 720p, or covert problematic video files. Then, you are allowed to scale it higher without blurriness. VideoProc can be a helpful converter. And here is the instruction.

  • Step 1: Download a VideoProc installer from the official site.
  • Step 2: Import target videos by clicking the “+Video” on the top or dragging and dropping.
  • Step 3: Hit the options icon on the right to open the codec interface, and move to “Resolution” selecting resolution less than the original one. Or move to “Video” at the bottom and select an output file format.
  • Step 4: Hit “Run” and wait for a little while.
Change video resolution

Final Words

There are countless reasons for causing a blurry or pixelated video in the course of scaling and zooming, this post has unveiled some of them for you. If you want a video clean to watch, keep these in mind: the purchase of a professional recorder and monitor, applying vector-based video or change resolution, and selecting a compatible file format for your video.
