I've been searching for a website that will host 60FPS or faster videoclips. The current popular ones, Youtube, Vimeo etc, all encode the videos to 30 FPS.
So far, the only solutions i've found are: Stream the video at 60FPS to a twitch.tv recording. Provide a direct link to the original file (FTP etc). Host my own webserver with a video website.
None of these are really optimal IMHO.
If anybody know of a website ala youtube that will allow a 60FPS or faster recording to be streamed at the original FPS, please write.
Thank you.

Slow your video to half speed (make sure pitch compensation is disabled so your audio won't be distorted), upload to youtube at 30fps, play back on youtube using html5 player at 2x speed. I believe you can set it to play at 2x by default in an embed, not sure though. That's just the first solution that came to mind, not sure how practical, it definitely works though.

It's not an optimal solution, and from the tests i've done, youtube drops frames when you do that.
Thank you for your suggestion though.

I'd like to know too, i record 120fps for Osu now (gotta have dat awesome frame-by-frame and slowmo) and it looks awful when slowed to 30

I doubt there are any out there. You are basically asking for double the bandwidth+
Would be nice though

Assuming people scale bitrate with framerate, yea.
Plenty of people make 10mbit 1920x1080 video's, and you can make a nice 120fps video with only 1-2mbit. >30fps is not impossible to do without a ton of data, there's little reason to go over 60 for realtime >video playback<

Isn't there some software that can make smooth looking 30 fps out of 120 fps by using the extra frames to calculate some kind of motion blur?

So everything gets encoded to 30fps youtube video bitrate... so when you double the fps you should be doubling the bitrate, right? I uploaded raw fraps video to get the highest quality possible and youtube encoded these down to a 111MB mp4 file for 1080p.

Not necessarily.. most formats don't actually store the entire image of each frame (some formats will store key-frames to help with seeking faster), instead just storing what changes between frames.

Oh god, somebody bring me my axe
Seriously though, no. It's an issue of not having enough data points - it's exposed really nastily in the osu replay/spectate engine. You lose a lot of cursor movement, and for example, an oval drawn as fast as possible is shown as a triangle, because you don't have as much data on the cursor movement
Osu is by far the worst game i've seen to expose this, you can interpolate data (for example if you have a ball moving across a flat background at 30fps, you can interpolate it to 60 pretty nicely), but not when you are missing key parts of the data, that is most of the point of the higher framerate in the first place
And in terms of bandwidth: 960x540, 120fps will use less data then 1920x1080, 30fps. It's really hard to work with something silly like 1920x1080, 120fps (though, that's less data than 4k@30hz) and it's kinda pointless having an ENCODED VIDEO played back at a higher framerate than the hz of your screen (a game see's a lot of benefit, but encoded video is a different matter) but i 100% think 60fps on any resolution should be embraced, no excuse not to
edit: Ah crap i actually read the post wrong. You're talking about cutting 120fps to 30, not 30 to 120. Same issue, you can't really condense 12 datapoints into 3 in any meaningful and good way

There is, but the intended result of using that technique is different than what people look for with 30->60fps.

Maybe there's a paid service for this then? As in, i pay to upload, but everybody can view them.
