Assuming you mean Vs. Recorder videos, you can go to the Global Terminal in Jubilife City, where you can find Battle Videos by popularity, Pokémon, battle location, or trainer residence. You can also record your own at the Battle Frontier or in the Colosseum.
the vs recorder only records battles that you have with your friends (or enemies!). When you do a linked battle, it should record automatically.
IT IS POSSIBLE! GO TO YOUTUBE AND SEARCH "THE RISING FIGHTING SPIRIT RECORDER" AND THEY HAVE LOTS OF VIDEOS WITH PEOPLE PLAYING IT ON THE RECORDER.

The most common use for a camera with a video recorder function is to take spur of the moment videos. This is especially true for people that enjoy taking videos of disasters.
