Sorry, that was page 136.
My strong suggestion is that you read, or at least scan the entire manual. You have a very complicated and capable camera, but if you don't read the book you won't know all it can do.
Unless you have a Mac, you deserve to put the Panasonic software that came with your camera on your computer. It will enhance what you can do with your "slow mo" video.
If you did not know it, an online manual like that can be searched. Do a Ctrl+F and type in "RAW". You can also click a line in the table of contents and go to the subject.
If you have any kind of smart phone, tablet or computer you can load that manual. My wife has here camera manuals in her Kindle readers. (Yes, she has two! One in color and one in B&W!)
