On the details screen in the upload wizard, you can add information about the media file.

The required fields are:

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

Although adding Tags is not mandatory, we suggest that you add some information which, relates to your video, this makes it easier for users to search and find your video. If you add a unique tag, this will allow a user to see all your media files.

For students, a tutor may suggest a using particular unique tag for your work, this method is useful for students when they are submitting assessed work, e.g. Module Name/Year.

If your video is just a Test file, please add the word TEST as a tag. Users Test files are removed from the system annually during the summer break and this helps the system administrators to ensure files are correctly deleted.


Categories

Screenshot of Category choice

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 UCL All Staff category allows any staff member to view your content but they need to login to MediaCentral to view. 
  • The UCL All Student Category is just for the content which is specifically aimed at students rather than staff
  • UCL All allows everyone at UCL to see your content, this requires users to login with their username and password

Always use one of the categories described. If you have content that 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 the content which has been previously defined as sensitive, or has some restriction to that Faculty or Department.


Personal (Private), Personal (Public) and Public Access

  • The Personal category is private to you. Only you can view or hear the content. You cannot share this content with others
  • The Personal (Public) category hides your video in the portal. This works really well if you want to show the video to others before changing to full Public Access, or if you want to let a select group view your video. To do this please use the Share link, this is the three-pronged icon on the top-right above your video.

Email, Twitter and Facebook Share icons
  • Students wishing to share content with their tutors should use the Personal (Public) category especially if submitting work for assessment.
  • The Public Access category allows your content to be viewed and downloaded by anyone. You can share this content via social media channels or using the Share link and a widget in Drupal, display content on UCL websites. For UCL WordPress sites use the Embed code. 

Thumbnails

  • The thumbnails screen presents eight thumbnails extracted from a video.
  • Click a thumbnail to use it as the media preview on the library home page. 
  • If there is a category thumbnail, you can check that box to use that generic thumbnail instead. 
  • Alternatively, you can add your own thumbnail image. Click on the Browse button to find your image on your computer and Mediacentral will use this.
  • For best results use an imagesized at 640px x 360px and formatted to either .jpg, .png or .gif. 
  • If the file is audio-only, an icon of a film reel is used in place of thumbnails. Ideally, you should add a personal thumbnail image for all audio files.

Upload Confirmation

The confirmation screen shows the media 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 your media to the encoder and takes you to your media content page, where you can preview the media once it has processed, as well as manage your media uploads.

Tip: Please note that your file joins a queue for encoding and sometimes this may take some time to process - you should always allow 8 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.
