Required Fields

The required fields are:

  • Title
  • Category
  • Description
  • Email address
  • Disclaimer check box, here you agree to the Terms of Use.


This function allows levels of access. Mediacentral is set up for users to share their content and to promote UCL to the wider world. However, you can restrict access by using the following sub categories:

  • The Personal category is private to you, only you can view or hear the content. You cannot share this content.
  • The Public Access category allows your content to be viewed and downloaded by anyone. You can share this content via social media channels or by the provided link. You can also embed this content into UCL or other webpages.
  • The UCL Staff category allows any staff member to view your content but they need to login to MediaCentral to view. 
  • UCL All allows everyone with a UCL username and password to see your content.

Always use one of the four categories described. If you have content which is sensitive or that you think should be restricted in some way, please contact the Mediacentral team. 

You may see a unique category e.g. Institute of Education when you are uploading or editing your content. Please do not choose these, unless you have been advised to do so, they are there for content which has been previously defined as sensitive, or has some restriction. 

Personal Category image


The thumbnails screen presents eight thumbnails extracted from the clip. Click a thumbnail to use it as the media preview in the library home page. If there is a category thumbnail, you can check that box to use that generic thumbnail instead. If the file is audio-only, an icon of a film reel is used in place of thumbnails.


You can upload an image to use as the thumbnail by clicking the Browse button.

Associated Files

If the use of associated files has been enabled by the Mediacentral administrator, you can add a captions file and attach up to three additional files or URLs. If associated files are not supported, you will see the confirmation screen instead.

Upload Associated Files

Captions Formats

Captions files can be added by clicking Browse. Captions must be of type:

.srt, .vtt, or .dfxp

Attachment File Types

To add associated files, give the file an upload name and click Browse to select the file. The allowed file types are displayed above the title box:

.doc, .docx, .ppt, .pptx, .xls, .xlsx, .pdf, .swf,.jpg, .gif, .htm, .txt, .zip, .mp3

Associated URLs

To add a URL, check the box and enter the URL. You can add a maximum of three files and/or URLs.

File Deletion

When a file has been uploaded, it will be listed below the browse box. Should you make an error, you can delete the file by checking the box and clicking Delete selected files.

Upload Confirmation

The confirmation screen shows the clip details. If you need to change the upload properties, use the tabs at the top of the wizard. Once all of the information is correct, click Finish on the confirmation screen. This submits the clip to the encoder and takes you to your media content page, where you can preview the clip as well as manage your media uploads.


Tip: Please note that your file joins a queue for encoding and sometimes this may take time to process - you should always allow 24 hours to guarantee your file has been fully processed and available.

Mediacentral encodes the file in the various streaming formats which are used to distribute the content to different devices. Your media content page indicates that the video has not been encoded until the encoding process has finished. Once the video has been encoded you will receive an email confirming the file has successfully encoded and is available in Mediacentral.

Should for some reason the upload and encoding fail, you will receive an email explaining what to do.
