We intend to reduce the risk of conflicts and errors by reducing the amount of Flash content in our system. From 2020 onwards, you will be unable to add new Flash-based files (such as .flv and .swf) to the Media Library in ‘Item Authoring’.
Therefore, we advise you to find new file formats for your media content. For example, you could add an HTML animation as source material to an item.
Note: For more information, please speak to your BTL Account Manager.
For more information about the features that are currently supported in HTML delivery, please see this article.
