JustPlay deserves a spot on this list of Mac MP4 player apps to consider in 2021. Why? Well, while it’s not a free app, after using it for a while, you’ll be able to see why many consider the small price to be insignificant, compared to the value you get from this app. It can deliver high quality 4K and 8K resolutions with ease - thanks to its hardware acceleration and under-the-hood processing power. It also comes with a ton of highly-desirable features like offering many viewing options, deinterlacing for older videos, and on-the-fly picture tuning for color, sharpness, brightness, and more.
- Deinterlacing feature to smooth out older videos
- Intuitive Touch Bar support
