Quite a new user.When filming in 4K what is better, 24fps or 60 fps? Is the differnce noticeable? Is there a big difference in file size?

Hi there. Thank you for reaching out. A 60fps video takes more frames per second, it shows more detail and more texture than the other frames, while the 24fps is used for standard videos, the lower the frame rate, the longer the shutter is open, and the lighter you can get into the camera. You can check out the difference between the two frame rate using the videos online for your future use. Thank you for your continued support!

Hi ! 60 fps is better. The higher fps, the smoother the picture or video will be. While the file size is also larger. If you're shooting fast moving objects, the differnce would be noticeable, whereas not. To be honest, shooting at 24fps is sufficient for most everyday filming.
