Multimedia

Field / Button	Explanation	Conditions
Player is displayed	If the checkbox "Player is displayed" is selected, the multimedia will be shown to the solver in the location specified by the content block. If the checkbox is not selected, the content block will not be displayed — this can be used for audio files or when referencing the file in another text editor content block.	Selected by default. Displaying the content block in another text editor content block is only available for audio files. In such cases, the audio file uploaded to the Multimedia content block can be selected from a dropdown menu in the HTML5 audio element.
Initially invisible	If selected, the display of the content block can be triggered, for example, by buttons or multiple-choice questions (it will be displayed after the participant makes the corresponding selection).	By default, it is hidden and will appear when clicking the 'More data' link. The "Player is displayed" option must also be selected (it will be automatically selected upon saving).
Drop files here or click here to upload	You can drag and drop multimedia files into the field from another window. Double-clicking the field opens the option to browse and upload files from your computer. Multiple files can be uploaded to a single content block. When the player is displayed, the players for these files can also be configured individually.	If multiple files are uploaded, they will be displayed together in a single content block when the player is shown to the participant. For audio files, they can be individually selected and displayed in a rich text editor.
Add a URL reference	Clicking will open a text field for entering the URL reference.	Button.
URL	A text field for entering the URL.	A text field. It appears when the "Add URL reference" button is clicked.
Add	Button to add a URL. Multiple URLs can be added to a single content block.	Button. It appears when the "Add URL reference" button is clicked.
If any files are added, the following options will appear.

Auto Start	When selected, the multimedia file will start playing automatically when the page is opened. If not selected, the multimedia file will play only when the participant clicks the corresponding button.	Checkbox.
Width	The width of the video player displayed to the user. If left empty, the video will be displayed in its original width.	Numeric field. Used for video files.
Height	The height of the video player displayed to the user. If left empty, the video will be displayed in its original width.	Numeric field. Used for video files.
Cycle	Selecting this option allows the multimedia file to play repeatedly, meaning that once the file finishes playing, it will automatically start over from the beginning.	Checkbox.
No controls (Play button only)	The solver will only see a button to start the audio file.	Checkbox. For audio files.
Max number of listenings	The solver can listen to the audio file or watch the video as many times as specified here. The number of listens is counted, and relevant information is displayed next to the player. If pause is allowed, the listening can be interrupted at the pause point, and the user can resume from there. A full playback of the added multimedia file is counted as one listening session. Once the allowed number of listens has been reached, the solver will see the text "Audio has been listened" or "Video has been watched." If the "Play button only" option is selected for the audio file, an icon will be displayed.	Numeric field.
Disabling pause	The solver cannot pause the video or audio file; they must watch or listen to it from start to finish.	The solver will see the pause button, but it will not function.
Max number of listens	It counts the number of listens.	Text field, where letters and numbers can be entered. It is pre-filled by default.
Mark files with the same name (only the extension differs) as different formats of the same track	If selected, a file in a different format can be added (if the browser does not support a certain file format, a compatible file format can be added instead).	Checkbox. The file names must be the same; only the file extensions can differ.
Download files	When clicked, all files uploaded to the multimedia content block will be downloaded as a zip file.	Button.
