There are several reasons why your videos may come out blurry. The most common factor causing a video to be blurry is the vibration, which could be caused by your trembling hands when shooting videos with your phone, DV or DSLR camera. Usually, this kind of vibration can be fixed or compensated if your shooting device comes with an optical image stabilization (OIS) or digital image stabilization (DIS) feature. However, there is another big reason that can cause a video blurry — the subject being captured was moving fast; and the 3rd major reason is that you simply lost the focus when the shooting took place…for the latter two cases, even the best image stabilization technology today on a camera finds it hard to prevent the video being blurred.

Hence, this problem can only be fixed during the post production stage, with a video sharpener software. Here is this article, we’ll show you how to sharpen videos with some popular video editing software, such as iMovie, Premiere and the AI-powered UniFab Video Enhancer AI on computers.

Section 2. FAQs

  • Can I sharpen a video online?

Well, sharpening videos is quite different from sharpening an image. Video sharpening is a computing-intensive and time-consuming task that is very demanding on hardware capacity. Given the fact the even sharpening a small video clip on a computer with top class CPU and GPU costs a considerable long time, and during that process, your computer will be significantly slowed down that you cannot run any other GPU-intensive programs, it is not possible nor practical to sharpen video online directly from a browser. So, the answer is no.

  • Is there any sharpen video apps that I can use to sharpen blurry videos on my smartphone?

Unfortunately, we cannot say for 100% sure that there isn’t, however, it is really hard to find one that really does the job right for you, no matter on iOS or on Android. Even there is, it’ better to take it with a grain of salt. The reason is obvious, like mentioned above, even the strongest computer takes a long time to sharpen a small video clip. So there is no guarantee to count on a smartphone for the job.

  • How to sharpen video in iMovie?

Well, it feel sad to say that iMovie does not feature such a function. But it is the truth. So you have to turn to other 3rd party video sharpeners to do the job for you.

Section 3. Wrap up

When shooting videos with whatever device you have, always try your best to minimize the side effect of vibration to maximally avoid blurry videos. To do that, a better camera with optical image stabilization or digital image stabilization feature may help a lot, as well as a tripod to steady the camera instead of holding it with your bare hands. That said, even with the best camera, it’s hardly to completely prevent your videos from becoming blurred, especially when you are shooting a moving object.

Thus, when your videos do come out blurry, there is no need to panic either. You can sharpen blurry videos with 3rd party video sharpening software at the post production stage, like the tools we’ve mentioned in this article.
