World First YouTube 60fps footage © 2011

(or)

YouTube Goes Nuts with 2160i

(cross converted from 1080p60)

For now, it's just 15 seconds:

How to view 60fps:

1. Download the 4K version
2. Play in VLC using "Linear" deinterlacing filter.
3. Set size to "half" or play full-screen.

VLC being VLC, you'll have to muck around with getting playback to kickoff again once you've forced deinterlacing to activate.

In the next few weeks I'll be uploading the rest of the footage.

This will push the new upload limit of 20GB.

It will create a 4K download of 40GB though …

YouTube's own encodings are typically twice the file size and half the quality.
