Thank you for your reply.
I assume that if a footage is shot in 60fps then it should play back in 60fps real time, not in slow motion right? But the files I received are from the card itself directly from the camera. There are no conversions or modifications made on the footage yet. I just preview them and they appear to be in slow motion.
Director: claims footage was shot in 60fps Arri Alexa.
Editor: reports the footage is slow motion in 30fps.
I don’t know if there is something wrong or DOP mistake on camera settings.
