+I was having stuttering problems playing some mp4 files (e.g. 4K 4:2:2 10-bit AVC) in windows on vlc and windows media player. The files played back smoothly in Davinci Resolve so it was a codec issue. I had disabled Windows Store so the default way of installing the codec wouldn't work for me.

 The second problem is that windows will not generate thumbnails for these codecs natively,
 [[https://www.videohelp.com/software/Icaros|Icaros]] is the standard solution for thumbnails.
 I installed [[https://codecguide.com/download_kl.htm|K-lite Codec Pack]] which includes Icaros.
