In regards to uploading file in laravel

Hi everyone, hope all is well. I am having this problem. I have created a form where you can upload video files, but I notice that when uploading it, video takes time to upload depending on the size of the file,so to avoid people staring at a screen for a long time waiting for their video to upload I saw this example on the this website about creating a progress bar. I tried it out and yes its working, like it saves to the public app folder and also it saves to my aws3 bucket folder as I requested but I noticed that its not saving the file in the database and I don't know why it by passes the database. here is my code below

//fileUpload.blade.php

 <div class="container">
    <div class="card">
      <div class="card-header">
      </div>
      <div class="card-body">
            <form method="POST" action="{{ route('fileUploadPost') }}" enctype="multipart/form-data">
                @csrf
                <div class="form-group">
                    <input name="file" id="poster" type="file" class="form-control"><br/>
                    <div class="progress">
                        <div class="bar"></div >
                        <div class="percent">0%</div >
                    </div>
                    <input type="submit"  value="Submit" class="btn btn-success">
                </div>
            </form>    
      </div>
    </div>
</div>

            return false;
        }
    }
 
    (function() {
 
    var bar = $('.bar');
    var percent = $('.percent');
    var status = $('#status');
 
    $('form').ajaxForm({
        beforeSubmit: validate,
        beforeSend: function() {
            status.empty();
            var percentVal = '0%';
            var posterValue = $('input[name=file]').fieldValue();
            bar.width(percentVal)
            percent.html(percentVal);
        },
        uploadProgress: function(event, position, total, percentComplete) {
            var percentVal = percentComplete + '%';
            bar.width(percentVal)
            percent.html(percentVal);
        },
        success: function() {
            var percentVal = 'Wait, Saving';
            bar.width(percentVal)
            percent.html(percentVal);
        },
        complete: function(xhr) {

            alert('Uploaded Successfully');
