============
Hey Benny!

The below video, GH010002.MP4, is a 4k 30fps h264 that required I set threads
to at least 2 to mplayer in order to play error free.  The mp4 called
GH010003.MP4 is a 1080p at 30fps and played fine without the threads switch. 
They were both made with a borrowed "GoPro Hero 8 Black".  It has a waterproof
case and I hope to have footage soon starring sharks of The Stuart Channel,
which as luck would have it is withing spitting distance from where I am
currently sitting.  Please stay tuned for further details ... maybe ... we'll
see what happens.

Anyhow 4k movies are doable but are very heavy byte-wise and from what I see
today 1080p still wins.  My neighbour argues that a 48" or greater monitor will
probably start showing the difference.
