While recording the video it just stops in 15 pro max, camera glitch? Video glitch?

I am worried since my iphone 15 pro max whenever i try to shoot, not always but once or twice everyday, video pauses and doesn’t record i need to reshoot the video again in order to capture the video. Is it normal? Or it’s just me? Because when i was buying the phone I didn’t find problem with camera issues, but facing first hand kinda scares me. HELP!!
