Lay the ribs on the top rack of the grill (away from the coals, if you're using briquettes). Reduce gas heat to low, close lid, and leave undisturbed for 1 hour. Do not lift the lid at all. Brush ribs with barbecue sauce, and grill an additional 5 minutes.
You can store about 27 hours and 30 minutes of video on a 64gb memory card.
Below is a chart that shows the estimated amount of time per gigabyte used for each of the Mode and Quality settings in our cameras. To determine how much time a card will hold, multiply the size of the card by the number of minutes for the settings you want to use. Then divide that number by 60 to determine the number of hours. Example: 16GB card X 15 minutes per GB (720p @30fps on High) = 240 min. 240min / 60 = 4 hours.
