Frequently Asked Questions and more
- How do I find my video after uploading
There is a bug in the system which we are currently investigating, normally you can see your media files once encoded by visiting the Mediacentral home page and clicking on My Account > My Content, and clicking on Yes in the "Encoded" field. This feature has stopped working and you will get a message Invalid URL.
The simple solution is to actually check your Outlook inbox and find the email from Mediacentral, this contains the link to your video and by following this you can get the Share or Embed code.
- I cannot access, upload or play certain videos since the Mediacentral move to the Cloud
Mediacentral has now moved to the Cloud, however, some people may be experiencing or having trouble playing, uploading or accessing content.
One major change since the move to the Cloud, is that Mediacentral now requires you to login using Single-Sign On or SSO, to access your account. Before this can take effect, it is important that you:Sign-out of all your UCL accounts and web applications from your web browsers e.g., from Google Chrome, Firefox, Safari, Microsoft Edge. Please check all your different devices e.g. desktop computer, laptop, tablet smartphone etc., and sign-out of your UCL web applications there too.
If problems still persist, please contact the Mediacentral team.
- Open browser and clear cache and browser history.
A tip for ensuring you are signed-out of your UCL web applications, is to:Completely close and quit your web browsers including any open tabs.
- I get an Error Code 232011 or 224003 notification when I play a video?
We note these errors only seem to happen with Apple devices. If you see an error code displayed when trying to playback video such as 232011 or 224003 error, then in the first instance:
- Please check that you have the most up to date version of all of your web browsers.
- It is important to update browsers regularly, primarily for security purposes.
- Once you have updated your browser, it is good practice to restart your device to ensure any old settings are deleted.
If the problem persists:
For users who prefer Chrome for Mac, we have created a workaround:
- SSL certificates on UCL websites were revoked due a security update , but we have discovered that Chrome for Mac is still referring to an old revoked SSL certificate.
- We have created a document which outlines the steps which are required to manually update the SSL certificate, please contact the Mediacentral team to access the information.
- Simply read the document and download the attached .crt file
- Double click on the file and it should automatically open Keychain for Mac and update the certificate.
- Close and reopen Google Chrome for Mac
If you need additional assistance, please contact the Mediacentral team.
- Will my videos play in countries that block YouTube and Vimeo content?
Yes, Mediacentral does work in countries that block mainly Google-hosted content. However, this should be caveated by saying the video viewing experience will be dictated primarily by a viewer's broadband speed (bandwidth) which can vary and that some people viewing may not have the best of experiences. Also, it is important to note that the services delivered are at the behest of any new firewall rules brought in by any national government in the future.
For assistance to those students who are currently based in mainland China who need access to educational resources which support their learning activities UCL has created the China Connect service, full information on the China Connect service is on the website https://www.ucl.ac.uk/isd/services/get-connected/china-connect
- I'm leaving UCL but wish to transfer ownership of my media to one of my colleagues?
We are working on a simpler solution that will allow media to be transferred to another user/staff member.
- Only media files that are in the category Public Access can be transferred to another staff member.
- Before you finally leave, it is important that you contact the Mediacentral team for assistance in transferring the ownership of your media files if they are in use on a Moodle module. The team will discuss the options to allow you to make the best decision for another staff member to mage and own access to this media content.
- Ideally, before leaving you should at a minimum move any content that is Personal (Private) or Personal (Public) to a category, if your team, department or faculty have previously requested a category, then the media can be reassigned to that. Alternatively choose if appropriate the category - Public Access, this will ensure any videos which are embedded in Drupal or other systems continue to play. You should note that if another individual within your team or department takes ultimate ownership of your media, you should take time to consider any implications, regarding copyright, GDPR and similar permissions.
- Media content that is not viewed once you have left UCL will be removed from the system at the end of following the academic year.
Please request a change of ownership for content that is in use and may be required in the foreseeable future.

Support for Learning and Teaching and using the Moodle Media Resource
- FAQ's when using the Moodle Media Resource
It has been advised by UCL Digital Education that media files that are part of a taught module should be uploaded through the Lecturecast system, which connects these files to a Moodle module, especially where these are lectures. Information on adding content to a class can be found here: https://wiki.ucl.ac.uk/display/LecturecastResourceCentre/Add+Content+to+a+Class
Existing Mediacentral content which is in a Personal, Public, or departmental category should be added to Moodle by using the embed code seen by clicking on the share icon on the top right or your video.
The system still allows you to use the Moodle Media Resource if that is considered a more appropriate method of distributing media to students. See https://www.ucl.ac.uk/mediacentral/moodle for help
- Do I use the Mediacentral portal or Moodle to upload and view my videos?
If you wish to share your video with the world, then adding the content directly through the Mediacentral portal is the best method. However, if you just want students on a particular module to view the content then please use the Lecturecast direct upload to your Module.
- Can I upload multiple files?
If you have a significant number of video or audio files that you wish to add to Mediacentral or your Moodle course, please contact the UCL Mediacentral team for further help and information.
- What media file formats can I upload?
When uploading media files, please check your media is one of the approved file types. These currently are: .avi, .flv, .mkv, .mov, .mpg, .mpeg, .mp3, .mp4, .wav, .webm, .wma, .3gp.
- Who do I contact for further information on using Lecturecast for uploads?
- How can I choose my own thumbnail image?
During the upload process, it is possible to choose your own thumbnail image. This can be an image that better reflects your media content, instead of the thumbnails that are automatically generated by the system.
- When uploading and you arrive at or select the section marked Thumbnails
- Next, choose the button marked Browse
- This will then take you to a file chooser where you can select the image of your choice.
- Once selected, this will become the new thumbnail image.
It is recommended that the image you choose has:
- a JPG or PNG image file format a minimum image size of 640 x 360 - (Width x Height)
- a maximum file size of 1 MB
- How long will my file take to upload?
This depends on the size of your file, its best to only upload files that are 1080p as few PC monitors display 4k video.
- Processing time - my file is still not available?
Unfortunately, we do not have the same processing power as YouTube and all files go into a queue - please be patient, the transcoding of your file is on a 'first-come, first-served basis and at peak times you should always allow 4 to 8 hours to guarantee your file has been fully processed and available.
- Why can't I see the content I've previously uploaded into Mediacentral?
The Mediacentral portal is the interface for publicly available content and although all media sits on the same servers, the security and access for Moodle content is kept separate for obvious academic reasons.
- Unsuccessful uploads - what happens, what do I do etc.?
If your file fails to upload you will receive an email letting you know there is an issue. The support team also receives this and we will look to ascertain if the problem is a system error or a problem with the file. Normally the issue is due to poor connectivity, UCL's infrastructure is more stable, so it is always best practice to upload when on campus. If you are working from home try and use an ethernet connection if possible.
Also, check that the format of the file you have uploaded is on the list of approved filetypes and is under 5Gb in size.
- My Media has failed to load or play?
On rare occasions your media may not play, the main reason is normally that your browser probably requires updating, or is set to play via Adobe Flash and this is now blocked for the majority of browsers. All content in Mediacentral is set to play in HTML5, and will ONLY fall back to Flash if your browser is not HTML5 compliant.
If your content will not play using Desktop@UCL then please contact the Mediacentral team.
- Editing, is this possible?
Editing of your video content is now possible using the Trim, Chop, and Export function in Mediacentral further information is on the general upload pages of the website, if your project is more substantial please contact the UCL Educational Media team.
- Can I upload & view from mobile devices?
Yes, this is possible, but generally not advisable if you are on the move. Try to do this where you have good access to WiFi rather than using your data allowance. To view login to UCL Moodle as you would do normally.
- Can I update a media resource added by another tutor?
Yes, you can do this. However, only do this if you have a good reason to and you also have equal authentication rights as an instructor.
- How does a student upload media?
This feature will be implemented in the summer 2020. If as a student you currently wish to add a video or audio file to your UCL Moodle module then use the UCL Mediacentral portal. Follow the process to upload as described here and make the content Personal(Public) to you. It is possible then to share or embed the content but your video will not show up in the portal.
Once your file is available, always use the UCL Mediacentral Share link to add to Moodle.
