I have lots of 4k videos that I took on my GoPro recently. They play perfectly on the GoPro itself and on my iPhone 7. But, when I downloaded them to my laptop via SD card and play them using Quicktime or VLC, they are very choppy.
I tried downgrading the video quality to 1080p using some free online tool, but the result was very blurry. I would like to retain the 4k definition if possible.
I've also tried connecting my laptop to a 4k television via HDMI, but the videos were still choppy.
My laptop is a 2015 Macbook Pro with Retina Display, 8GB RAM, 2.7 GHz Intel Core i5 processor, and 250GB SSD.
Any idea how I can resolve this?
