I downloaded a youtube video with 4K 30fps and 4K 60fps resolutions. The 30fps can play smoothly in the latest VLC player but not the 60fps. Is the Macbook not capable of playing 4K 60fps smoothly or are there any settings I can tweak to improve or even other players that can do the job?

HEVC file? Try IINA, or if it’s in QuickTime format, try QuickTime.

4K 60 Hz HEVC (even 10-bit) should work fine but vlc isn’t the best player for this. Also, there are a few files out there that have problems.

Do you have a link to a file we could try?

It is a MKV file with VP9 codec which I downloaded from youtube using 4K Video Downloader.

I tried IINA. It is better. At least the video is not distorted at some point compared to VLC but it is still not smooth.

Oh. VP9 is not hardware accelerated on macOS. Too bad, cuz the Mac hardware itself supports VP9 hardware decode. Apple just refuses to implement it, probably because Apple originally wanted VP9 to die.

OTOH, this 10-bit 4K 60 Hz HEVC plays beautifully on the 2017 MacBook.

This file will bring a 2015 Core i7 iMac and a 2016 Core i7 MacBook Pro to their knees, but the lowly 2017 MacBook plays it just fine.

By the way, is IINA currently the best video player out there for Mac? Is it less resource intensive than VLC? I kind of like IINA UI but have been using VLC for a long time.
