Subtitles / Closed captions
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:m: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.
To consider
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.

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 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".
Course element
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 like this allow:
- playback with subtitles
- playback in different resolutions (especially relevant for mobile, or without WiFi-access)
- comments
- assessment
- landing picture by desire
Video Collection
Use the "Video Collection" page to browse through all videos available in your instance. To show a video in the "Video Collection" at least the "BAR" Access configuration needs to be assigned, which means it is automatically accessible to all registered users. The description of the info page is indicated automatically on the single page of a video, as well as in the assessment and the comment feature. If you miss a video, check the settings in the video settings in "Access configuration".
If you can't find the "Video Collection" entry in the main navigation in your OpenOLAT instance, it is either hidden by the administrator or you don't posses the required rights.
