Learning resource: Video
A video learning resource is created in authoring with the feature "Import" or "Import URL".
Therefore you select the desired video-file in the upload window and click on "Import". In the following step the form opens on info page.
Warning
To be recognized in OpenOlat as a video learning resource a video file prepared for the import needs to be in the .mp4 form.
If a description is indicated on the info page after the import, it can be shown as course description when embedding into the course.
If YouTube videos are imported via "Import URL" YouTube, metadata of the YouTube file, such as the title or a start image, are also imported.
Video settings
You can now further configure your video in the tabs of the "Settings" menu. The "Info", "Share" and "Catalog" tabs are analogous to other learning resources. For general information about the Settings menu, click here.
Metadata
In the tab "Metadata" you find general information like creation date and size of video file. Furthermore, as in other learning resources, you have the option to store information on authors, subject areas, main language, time required and license.
Replace poster
In the tab "Replace poster" you determine the picture which should indicate the video in the course area, in the catalog, on the Video Collection page, in the authoring as well as in the course. With the help of "Replace poster" button you can chose between 8 freeze frames of the videos. If you prefer an own picture, chose the button "Upload poster". If no poster is added, the freeze frame from the beginning of the video appears.
Attention
Please consider that such a pictures needs the same pixel size than the original video. The corresponding data can be found in the tab "Metadata".
Chapter
To group a video, chapters can be added. This simplifies especially the navigation in the video. A chapter is added with the button "Add chapter". The name of the chapter can be inserted. Additionally the begin of the chapter needs to be defined.
Alternatively the video can be stopped at the place, where the new chapter should start. Click the button "Add chapter". The begin is taken over automatically and only the name of the chapter needs to inserted.
Chapters can be edited and deleted.
Annotations
In addition to the chapter markers, further annotations and comments can also be stored at any point in the video, e.g. to highlight particularly important points or to supplement certain aspects.
Select the place where the annotation should be added and define the further settings, such as the duration, the position where the annotation should appear and of course the text to be displayed.
Quiz
Here you can add individual quiz questions to the video, which are either created directly or imported from the question pool. There are currently 11 different question types to choose from. The question can then be further configured.
In the tab "Configuration" you can define the time at which the question should appear, if there is a time limit or if it is allowed to skip the question or if another attempt is allowed.
In the tab "Selection" the concrete question as well as the answers are deposited.
The tab "Score" defines the type of points to be awarded.
In the tab "Feedback" feedbacks based on different criteria can be added.
Further information on the general settings of quiz and tests can be found in the chapter "Configuring test questions". For more information on the different question types, see the "Test Question Types" chapter.
Subtitle configuration
A video can be assigned with subtitles in any amount of languages. In OpenOlat subtitles are uploaded in the WebVTT format (Wikipedia article). The uploaded files need the ending .srt. Files with the ending .vtt are not supported. Subtitles can be created easily by your own. This format ist supported by most of the video player software. For every indicated subtitle line a time specification is needed in the following format:
h
s.msec example: 00:00:20.396 (time specification 0 hours, 0 minutes, 20.396 seconds)
Milliseconds need to be indicated to the 3rd position after decimal point.
Attention
The separators of the time specification need to be double point and point (as the example). Commas are not allowed
Inside the document, the first line needs to be WEBVTT.
Adding subtitles

.
CC stands for the american expression "Closed captions" (Wikipedia), and means that subtitles are invisible until they get activated by the user. In OpenOlat it looks like the following:
As soon as you move the cursor over the icon the list with the existing subtitles expands. The current selection is dyed.
Video quality
In the tab "Video quality" the resolution of the video is shown. As soon as a video is uploaded, videos in different resolutions will be created. This process can take a long time. The available resolutions are dependent on the settings in the administration area. Pending videos can be transcoded and not used resolutions can be deleted. In the video player the desired resolution can be chosen by the "Source Chooser".
Info
For videos uploaded to OpenOlat there is another tab "Video qualities" available. For videos added via "Import URL", the settings cannot be made.
Download
In the Download tab you can set whether the users are allowed to download the video or not.
Embed videos in courses
The course element "Video" allows the author to embed videos directly into a course. The video is either chosen out of the list of available videos in the authoring, or directly imported. Compared to videos embedded as a course element "Single page" - videos embedded course element "Single page" - videos embedded like this allow:
- playback with subtitles
- playback in different resolutions (especially relevant for mobile, or without WiFi-access)
- comments
- assessment
- landing picture by desire
- Combination with certain completion criteria in learning path courses
Video Collection
Use the "Video Collection" page to browse through all videos that are available in your instance. In order for a video to be displayed in the "Video Collection", the publication status "Published" must be set. In combination with the access setting "Open" it will automatically be accessible for all registered users. The description of the info page is automatically displayed in the individual view of a video, as well as the rating and comment function.
Info
If you miss a video, check the settings in the video settings under "Access configuration".
If you cannot find the "Video Collection" entry in the main navigation of your OpenOlat instance, either the administrator has hidden it or you do not have the required rights.
