Hi @lior_s99
you will always have cross-platform headaches with in-game recordings because the support of codecs is not universal across all operating systems and hardware. MP4 is the most supported so maybe it works on every single device (but I have no experience recording video inside a Nintendo or PS4 game).
Have you thought of scripting a Recorder Controller using Unity Recorder? See this thread .
I assume you’re trying to do something like record a regular 2D (not 360) video of the VR pawn, as if the avatar were taking a selfie. In this case, position your camera in the scene and use the above thread as a tip to start recording.
Cheers
** EDIT: just realized that Unity Recorder does not work (yet) in standalone builds, so this might not be the right solution for you.
