Greasy Fork is available in English.
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.
It is already supported — automatically — although it is not obvious.
If you hover over the 720p or 1080p M4V, you will see the itag is 299/298 (1080p/720p) instead of the usual 137/136 (1080p/720p).
Note that only the 1080p/720p M4V is 60fps. The 720p MP4 (itag 22) and 480p M4V (itag 135) remains as 30fps.
I have downloaded the above video at 1080p to confirm that it is indeed 60fps.
Lastly, the M4V is a DASH video file, so you need to download the M4A audio file and mux them yourself.
The 60fps videos are now marked as M4V (HFR) in version 1.71, = High Frame Rate, so hopefully it is more clear.
New format 1080/60p 720/60p
Good job, thanks for update it.
Would you can give it support to "60fps youtube videos"?
This is one of them:
