I dont understand how to use HTML text as I uploaded the video to sosci under the filename "SurveyVideo-Compressed.mp4" then I put the code below into the text element as instructed and an error message came up. (in the manual, it says that it is also possible to use one format, so I will just stay with the mp4 file).
<video width="512" height="288" controls>
<source src="SurveyVideo-Compressed.mp4" type="video/mp4" />
</video>
Could you kindly help me as I need to make the survey go live very soon and I need the video to be included.
