This guide will provide three potential solutions for migrating/converting Flash-based presentation content to video hosted in Kaltura. Note that these processes will not recreate interactivity that may have been part of the original Flash-based package, including quizzes, links, menus, or other animations. Some of this interactivity could be approximated after conversion using Kaltura's Quiz and Hotspot features.
During its heyday, Flash was often the format of choice. It scaled well, it was powerful, and enabled interesting interactivity. However, in part because of its architecture and system-level access, it became a target for hackers and other bad guys as a conduit to users' computers. Adobe worked hard to patch and upgrade Flash to protect users but eventually announced that it would phase out its support of Flash. Browsers, in turn, as a security measure have begun to make it more and more difficult to play Flash content, with most planning to eliminate flash support in the next year. Chrome, for example, will not support Flash playback after December 2020.
Flash-based slide presentations are a common application of Flash in higher education courses, in part due to the popularity of a tool called Adobe Presenter as well as recordings of content created in or published to Adobe Connect. Adobe Presenter is a PowerPoint add-in that provides a workflow for creating and publishing narrated slideshows from within PowerPoint. One of the issues with these tools, particularly in presentations created with older versions, is they often published solely or by default to Flash format. These presentations often require browser permission to run (e.g. "Allow Flash") and/or have file extensions including .swf in their packages. More recent versions of Adobe Presenter and Articulate Presenter do publish to HTML5 format, which do not suffer from the same issues as Flash, and continue to be supported in modern browsers.
Therefore, if you are hosting recording presentations published from Adobe Presenter in Flash format, not only have you likely already seen problems with playback, as browsers have begun blocking Flash by default, soon you and your audience will have a difficult time playing the presentations at all, in any browser. Additionally, in some cases, particularly with older presentations, the original source files may not exist, such as the presentation itself or the related audio files.
There are at least three potential options for replacing these types of presentations published in Flash:
The first option is to simply create a new version of the presentation by creating new slides and then using either Kaltura Capture to capture a PowerPoint presentation and narration or by recording narration in PowerPoint and publishing to MP4, then uploading to Kaltura. This is a great option if your content is older and needs to be updated anyway.
This option requires access to the original PowerPoint show and the published package folder from the Flash presentation (e.g. Adobe Presenter). These tools generally publish a folder of files that support the presentation. Here are the steps for this option:
This option is used when you simply want to record the audio and video of a presentation using Kaltura Capture. Some considerations for using this option:
