Hi developer, I made a 120fps video using Flowframes and tried to play it using Potplayer and HereSphere. The video is fine in Potplayer but audio and video are out of sync when playing in HereSphere. Any possible solution?

I doubt the Quest 2's mobile processor can handle decoding 120fps videos on time, especially at high resolutions. Basically, the Quest 2 can't decode the video fast enough, and it's causing the video to get out of sync with the audio. You could try lowering the video bitrate, or lowering HereSphere's resolution setting and disabling HereSphere's autofocus to improve performance.
