I have posted a demo video clip of Youtube’s new 60 fps support.
To play at 60 fps, you must select 720p or 1080p viewing modes and use the Chrome browser and the HTML5 video player. The Flash player (used in many other browsers, by default) does not appear to support 60 fps and just stops working.
However, if you wish to watch 3D clips on Youtube, then you probably still want to use the Flash-based video player – but it appears we probably will not be watching 60 fps in 3D. It’s possible as we can always upload side-by-side 3D videos in 60 fps mode, but the HTML5 player will display them in their original side-by-side format – you may have to manually switch your TV or monitor to side-by-side 3D mode in that case, in order to watch in 3D.
Youtube has been experimenting with 60 fps for a while, but only with selected users. Today, 60 fps is now live for everyone.
YouTube now supports 60fps playback, and video games look amazing | The Verge.
I saw a prototype of this technology in 2013 – its awesome! Add glasses free 3D viewing to your Apple iPad:
Leveraging many years of 3D industry experience, Ooyavah has created a glasses-free 3D viewing solution for the world’s most popular tablet – the Apple iPad.
from Ooyavah. The product itself is named Pryzma.

It combines a state of the art lenticular lens overlay, on the Apple iPad screen, with use of the iPad’s camera to track your eyes in real time, automatically adjusting the screen’s content to deliver true and accurate glasses free 3D viewing your left and right eyes.
The Nikon 1 cameras – J1, J2, J3, J4, V1, V2, and V3 – use a “1 inch” sensor that is about the same size as “Super 16mm” film. The small’ish sensor is ideal for working with old 16mm lenses (I have one) or with various c-mount lenses. Ideally, the c-mount lens should provide a “1 inch” coverage. However, the photos below were shot using a Tamron 4-12mm f/1.2 lens having a 1/2 inch coverage. Except when zoomed in, in which case it covers the full frame with a very tiny amount of vignetting.
These macro photos amazed me – shot on an inexpensive Nikon 1 J2 with a CCTV c-mount lens! You can click on the photos for larger version, although these were uploaded at about half the horizontal resolution. The extremely narrow depth of field is pretty neat for a small sensor camera using an inexpensive wide angle lens!
The c-mount lenses I have used are often quite soft when the aperture is fully opened. Stopping the aperture down a bit improves sharpness. They also tend to have softness in the corners, or vignetting. This particular lens is very good for these close macro shots – the edge softness is obviously not a problem as it is supposed to be out of focus! But I would not recommend this lens for general purpose shooting of non-close subjects. I also have a Computer 12.5-75mm f/1.2 lens. This is useful mostly in full zoom (75mm end) but at f/1.2 it is very soft. Stopping it down to f/2 to f/4 greatly improves the image quality – and with the telephoto effect, does a good job for creating certain types of narrow depth of field. I would not use it as a general purpose lens, however.
I recently noticed that many of the “channels” I subscribe to on Youtube have made no updates for 9 months, a year or more. I just went through and deleted 30% of my subscribed channels because they are no longer posting videos to Youtube.
Wow. That’s quite a few. And it is worse than it looks because I kept subscriptions to several channels as bookmarks to some of their past videos – but many have not posted anything new in a year or more.
Youtube is definitely changing and it seems to be in the very early phase of turning into a new fangled Cable TV-like content distribution system. Youtube is resembling a Pareto distribution where a relatively few content providers account for the majority of views.
