Blur css applied to the video background, but shows blurred too on the edges like a "Glow"

Question

I have used css to apply some blur effect to my background video. But it shows as too blurred on the edges..... Is there any solution to apply flatten blur css for the video? or i want to remove that glow from video edges. Thanks in advance !

See my code below:

.project-col {
    display:inline-block;
    width:100%;
    position:relative;
    background:transparent;
    z-index:0
}
.video-col {
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    overflow: hidden;
    z-index: -2;
}
.content {
    padding-right:50px;
    padding-left:50px;
}
.video-col video {
    width:100%;
    -webkit-filter: grayscale(100%) blur(5px);
    filter: grayscale(100%) blur(5px);
}

<div class="project-col">
    <div class="video-col">
        <video class="video" autoplay preload="auto" loop>
            <source src="https://0.s3.envato.com/h264-video-previews/052c2cb4-9997-4833-ad53-2384dca08706/17458620.mp4" type='video/mp4' />
        </video>
    </div>

You could add inset box shadow to video parent:

.video-col {
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    overflow: hidden;
    z-index: -2;
    box-shadow:inset 5px 5px 15px #000000;
}

.project-col {
    display:inline-block;
    width:100%;
    position:relative;
    background:transparent;
    z-index:0
}
.video-col {
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    overflow: hidden;
    z-index: -2;
    box-shadow:inset 15px 15px 50px #000000;
}
.content {
    padding-right:50px;
    padding-left:50px;
    color:white;
}
.video-col video {
    width:100%;
    -webkit-filter: grayscale(100%) blur(5px);
    filter: grayscale(100%) blur(5px);
  
}

<div class="project-col">
    <div class="video-col">
        <video class="video" autoplay preload="auto" loop>
            <source src="https://0.s3.envato.com/h264-video-previews/052c2cb4-9997-4833-ad53-2384dca08706/17458620.mp4" type='video/mp4' />
        </video>
    </div>

Play with values a little - it could fix glowing edges...
