I am trying to create a Multimedia Component in SDL Web 8.5:

 - Multimedia type: mp4
 - File size: 860 MB

Uploading the file works fine, but while saving the item it gives the below error:

Steps taken:

 1. Added the following code in `web.config` file located under `\WebUI\WebRoot`

        <system.web>
          <httpRuntime  executionTimeout="100000" maxRequestLength="1073741824" />
        </system.web>
    
        <system.webServer>
           <security>
              <requestFiltering>
                 <requestLimits maxAllowedContentLength="1073741824"/>
              </requestFiltering>
           </security>
       </system.webServer>

 2. Increased the maximum upload size in IIS to 1073741824 from IIS manager and restarted the IIS.

Can you tell the solution for the above problem?
