Youtube started having 30fps video only stream with higher bitrate than 60fps stream for whatever reason thus affecting bestvideo selection. This can always be overridden with format selection string so this issue is created for information purposes.

Both have higher bitrate.

These:

303          webm       1920x1080  1080p60 5104k , vp9, 60fps, video only, 392.57MiB
299          mp4        1920x1080  1080p60 5974k , avc1.64002a, 60fps, video only, 479.71MiB

have lower bitrate than

137          mp4        1920x1080  1080p 10637k , avc1.640028, 30fps, video only, 602.33MiB

thus making 137 to be selected as best.

And why do you think that's wrong?

[satnatantas]

I never said that. I think that it is weird choice by Youtube. I bet that there will be other people scratching their heads about why 60fps is not downloaded.

I suggest a warning in console for example.
