Monitors runs at 60Hz so 30 fps is much better for watching videos than 25 pfs. In the case of 30 fps each frame remains 2 refresh cycles on the screen. In the case of 25 fps some frames remain on the screen 2 refresh cycles while the others 3 refresh cycles. This causes constantly change of speed of video playback - several times a second. For example the website InTheCrack.com use 30 fps in their 4K videos and it is very fluent on 60Hz 4K monitor.
Just set Video to NTSC model (30 fps) in the camera settings instead of PAL model (25 fps).
