My 2017 retina 5k iMac with 40GB of RAM and 4TB of SSD internal HD and minimum 30Mbps broadband connection can't play the Youtube 60fps version smoothly at 4k. It was shot at 4k60 and uploaded in two versions: 4k60 and 4k30. I uploaded a short clip of my son's girlfriend's chihuahua. Not here to argue any points.Ĭlick to expand.I've done some more testing this morning (GMT) but need some volunteers with different platforms/more horsepower than me to check my findings. Hope this info helps someone, and if I am not accurate in any statements, feel free to correct. Is it "better"? Depends on your preference and what you are shooting, and what your definition of "better" is. There is math involved to determine the rate of yaw to keep things smooth, and I am lazy when I fly, so I like the higher framerate of 60. Drone footage usually yaws a lot, so at the lower framerate, you need to be really slow when yawing to keep it sharp. I am not a video expert, but did shoot video commercially for many years - mostly theater work, along with being a semi-pro fotog. Longer exposure time for each frame with the ND filter, means more info to the sensor, better quality. The video with the ND filter will look way, WAY better, way more saturated than the video shot on auto shutter. You can shoot two videos in sunlight.both at 30fps, one video without an ND filter the other with, slowing the shutter speed to 2x frame rate with the correct ND filter. Here is another thing to think about.ND filters that slow shutter speed by limiting the amount of light to the sensor. The advantage of 60 is you end up with more to work with in post as long as you keep the shutter speed higher than the frame rate. You may notice a slight "stutter" in the video at 30 vs 60, but the advantage of 30 is higher quality and motion blur. Your shutter speed MUST be faster than your frame rate otherwise you get blank frames and duplicate frames in your final video. But.I think you will need to look really close to find the difference. Remember that.Ĭomparing the same scene shot at 30 vs 60 will more than likely look slightly better at 30. Framerate goes hand in hand with shutter speed. ![]() The slower the framerate, the more info/data the sensor can gather, hence the better the image quality, since there is more info. Frame rate is the # of pictures taken per second, shutter speed is the amount of exposure time per picture.
