Is there some specific way of encoding videos so that YouTube does not change their framerate back to 30fps? I'm trying to upload 60fps videos but YT automatically changes them to 30fps after processing.
Here are some examples of 60fps videos on YouTube:
I've tried lots of different codecs, resolutions, bitrates, containers, but still cannot get the right configuration.
I hope someone can help me with this!
Thanks in advance.

Have you tried uploading 60 fps flv file? Downloading one of the files then uploading it yourself?

Youtube re-encodes everything at a limited bitrate, so it will destroy the quality . It's supposed to.
sorry double post

The examples above are all old, before the changes at youtube
Also notice they are all tiny like 320x240 and less than a few MB
Damn, oh well.
If you hunt around for videos with occasional comb artifacts visible and then play them at the lowest YouTube quality available, sometimes they jump to 60fps. If you reduce the quality of some of the video samples posted (as in if it says 360p, try 240p), they are in fact still 60fps on YouTube. I think their conversion process is frame rate at high quality, interpolated field rate at low quality? 60fps at low quality doesn't seem to work with progressive video. Maybe there's still some magic trick..

You can see the 60fps effect by using one of the usual tricks to download to disk, then view in VLC, with "Linear" deinterlacer.
This takes advantage of the (stupid!) situation where you can go insane with megapixels, but not even SDTV with frame rate.
Frankly I don't see why YouTube is pursuing the pipe-dream of 4K and 8K video. Nobody has computer screens that high.
On the other hand, long after the first "HQ" feature, YouTube still doesn't truly support Standard Definition, either 60Hz 480i or 480p, or 50Hz 576i or 576p.
Info about YT at 60fps from TAS video site:
Enable YouTube's html5 player(required)
-Select a browser that supports html5 video(chrome, opera, ie9, safari)
Watch the below videos at 2x speed!

Yes the sound breaks, but as a quick 60fps hack what do you guys think?
