RAW, as BigAl says in the photography world is just the unedited pure capture data from the sensor. As soon as you take it into software and change any parameters, it will no longer be a RAW file and will be saved as some kind of regular format (.psd, .tif, .jpg etc.)
In the video world, there are fewer cameras that shoot true RAW. Most shoot some kind of log format to take advantage of the dynamic range of the sensor. As far as I know, unless you're flying a custom rig, a Sony Airpeak (which will mount a series of Sony cameras) or an Inspire, most drones will shoot some kind of proprietary log format. (S-log, Dlog, DlogM...etc) and not RAW video.
There are many names for RAW depending on the camera (DNG for photograohy is the most common) video RAW formats can be BRAW, ProRes RAw, etc.
RAW is in it's most basic definition is unfiltered, unedited camera sensor data and as soon as you do any manipulation, it ceases to be a RAW file.
