RAW files (or footage) is completely unprocessed output of the camera that hasn't been color-corrected, has poor unfiltered audio, and is missing all other things used by camera software for convenience sake. The upside is that RAW footage is the most high-quality source material you can get and thus it is the to-go option of professionals who would have opted to edit and fine-tune the footage anyway.
You cannot properly view RAW footage without specific software, however, which is why Video Asset Management has become an industry standard. With cloud-based VAMs, you can view RAW files wherever you have Internet connection without relying on having a computer with proper software laying around at all times.
