Hi Mkassem, I checked the portrait video mode, initially it appears there is only a 1x and 2x choice however when I press on the 2x a third option then appears under the initial setting, you can scroll across to 1,2,or3. There is however no 5x I can find in the mode - as yet. Maybe Samsung will develop further options as software develops. Hope you enjoy your S24U I am still figuring photo stuff out, hoping someone will put an indepth S24U photo/video on YouTube some point. In meantime I am googling all the setting terminology as I don't have clue, but exploring options is the fun of a new phone, enjoy your s24u 🤗
