I bought a 32gb just yesterday...and the video images are perfect...any chance yours is a fake? Just saying it may be. Edit....just found the packaging for my 32gb ....some differences between yours and mine....top of the pack the U3 and C10 are on opposite sides to each other...mine says micro SDHC yours micro SDXC...from where it states Delivers 4K...the printing is white, not gold....whether all these differences are just different markets, I don't know. HTH.
