Learning resource: Video
To be recognized in OpenOlat as a video learning resource a video file prepared for the import needs to be in the .mp4 form.
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. If a description is indicated on the info page after the import, it can be shown as course description when embedding into the course.
Note
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 Editor
In der Administration der Lernressource findet man den Link zum "Video-Editor". Hier kann das Video mit (interaktiven) Elementen ausgestaltet und weiter konfiguriert werden.
Der Video Editor umfasst drei Bearbeitungsbereiche: * Konfigurationsbereich * Timeline * Vorschaubereich
Konfiguriert werden können: Kapitel, Annotationen, Segmente, Kommentare und Quiz.
Tipp
Hilfreich ist es die unterschiedlichen Elemente mit verschiedenen Farben zu kennzeichnen.
Chapters
Jedem Video können "Kapitel" als Sprungmarken hinzugefügt werden. 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.
Ferner sind die Kapitel in der Timeline sichtbar.
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.
Segments
Segmente kommen in der Videoaufgabe im Kurs zum Einsatz. Sie markieren definierte Bereiche im Video, denen die Teilnehmenden vorgegebene Begriffe oder Situationen (= Kategorien) zuordnen müssen.
Comments
Kommentare können gezielt an einem bestimmten Punkt im Video gesetzt werden und zum Beispiel wichtige Kernaussagen des Videos hervorheben, ergänzende Informationen zum Thema oder Hinweise zum folgenden Videoabschnitt bereitstellen. Der Kommentar wird mit dem Namen der erstellenden Person gekennzeichnet.
Sieht sich der User das Video an stoppt es an der mit dem Kommentar versehenen Stelle. Um fortzufahren, muss entweder der Kommentar aktiv geschlossen oder der Play-Button des Videos manuell angeklickt werden.
Neben einfachen Text-Kommentaren und der Einbindung bestehender Videos (Import als Datei oder per URL, z.B. von YouTube) können Video-Kommentare auch direkt im Editor über die Recording-Funktion aufgenommen und integriert werden.
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 12 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.
Die konkret angezeigten Tabs für die Quizfrage sind abhängig vom gewählten Fragetyp. Im ersten Tab wird die konkrete Fragestellung sowie die Antworten hinterlegt. The tab "Score" defines the type of points to be awarded. In the tab "Feedback" feedbacks based on different criteria can be added. Im Tab "Vorschau" bzw. "Vorschau Lösung" kann man sich die Darstellung der Frage anschauen.
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.
Videokonfiguration in den "Einstellungen" der Lernressource
You can now further configure your video in the tabs of the "Settings" of the administration 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".
Subtitle configuration
A video can be subtitled in any number of languages. In OpenOlat, subtitles are uploaded in the WebVTT format (Wikipedia article). The uploaded files need the ending .vtt. You can create subtitles easily on your own. The format presented below is supported by most video players.
The first line of the VTT document must be the keyword WEBVTT, followed by an empty line.
Before every subtitle line, a time specification is needed in the following format:
hh:mm:ss.msec
Example: 00:00:20.396 (time specification 0 hours, 0 minutes, 20.396 seconds)
Milliseconds must be specified to the 3rd digit after the decimal point.
Attention
The separators of the time specification must be colon and period (as in the example above). Commas are not allowed.
The following example shows the beginning of a typical VTT file:
WEBVTT
00:00:00.000 --> 00:00:04.000
Where did he go?
00:00:03.000 --> 00:00:06.500
I think he went down this lane.
00:00:04.000 --> 00:00:06.500
What are you waiting for?
Adding subtitles
To add subtitles to a video
- Open "Administration → Settings",
- navigate to the tab "Subtitle configuration",
- click the button "Add subtitle".
- In the new window chose the language in which you want upload the subtitles and
- select the corresponding file.
- Click "Upload".
Already created subtitles are listed in the table and can be deleted there as well.
Displaying subtitles
By default the videos in OpenOlat are played without subtitles.
As soon as
subtitles are available, the following icon will be shown in the video player:
.
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 colored in.
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.
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.
