You can store about 27 hours and 30 minutes of video on a 64gb memory card.
For example if your card reader or camera is compatible with a SDHC card with a maximum capacity of 32GB using this reader or camera to format a 64GB SDXC card will result in the card being re partitioned to 32GB (~27GB usable capacity)
