I am trying to show a YouTube video to participants without sound.
The file is too big to upload to Qualtrics directly, so I uploaded to YouTube and embedded the link into my survey. I had previously removed the sound from the MP4 file, but somehow YouTube un-removed it during the upload. Nothing I try in YouTube itself will remove the sound, so I am hoping that it is possible to remove once the file is in Qualtrics.
Currently, I am using the following code:

It auto-mutes the video, but does not autoplay or hide the controls.
When I tried using the following code, it autoplays and hides the controls, but it unmutes the video so you hear the sound.

Without adding music, is there a way to remove the audio AND the controls, so participants cannot manually unmute the video?
Thank you!!
