They've made the odd choice of placing the QR code as a mask on the video via CSS, rather than positioning a black & transparent image over the video (which would allow long press).

Not sure why they've done this, perhaps something about the HDR approach requires both the black and white to be a part of the same video render.

Also - I'm not sure if it's a browser default or some other website CSS but imo there's no real reason long press shouldn't work on a video anyway... videos need accessibility too.

odd choice indeed, I wasn’t thinking clearly when I experimented and wrote the article.

putting a black and transparent image atop the video sounds like a much better idea — i will try it and see if it works. thanks for the suggestion!

Not thinking clearly! I can barely write anything when I am thinking clearly. Great work on the technique, it's ingenious.
