Download YouTube videos. Video formats are listed at the top of the watch page. Video links are tagged so that they can be downloaded easily.
If it's High Frame Rate, I will put "4K (HDR)". But let me know if you see a video without. Maybe the detection method has changed.
I finally understood what you meant! :smiley:
You mean to show the FPS in the tag label for the video thumbnail links. Got it.
Good idea, but then for all resolutions with 60fps, as there are:
HD 720p60, HD 1440p60, 4K 2160p60, 5K 2880p60 and 8K 4320p60.
In v2, the frame rate is now shown in the video tag if it is >= 45 FPS.
Cool, but what is 3K ?! :o 
1440p maybe?
And u1080p ?! :| 
And what is 2k? I think rather maybe 2048x1080 ? 
I found this: thepowerpointblog.com/hd-2k-4k-resolution/
Because 3K is not an official "K" resolution - instead of for example 4K, 5K and 8K (and future 16K (15360 x 8640)).
3K is not official, but in general, x K is a nice shorthand for x,000 horizontal pixels.
Can you also show fps along with resolution on the top left corder?
like 4K@60 or 4K60p instead of 4K
