Oasiz idea. Enable YouTube's html5 player(required) -Download a browser that supports html5 video(chrome, opera, ie9, safari) Watch the below videos at 2x speed! Gunstar Heroes Super Mario World Super Metroid Alisia Dragoon Reference: Super Mario World Super Metroid Yes the sound breaks, but as a quick 60fps hack what do you guys think? Edit: PC games look pretty: http://www.youtube.com/watch?v=AhamPScmrLQ

I must admit, this looks damn good if we don't take the sound into consideration.

Unfortunately it doesn't work as intended here: speed changing controls don't change anything. I'm on Opera 10.60 beta, got the same result on Chrome at work. I'm wondering what exactly is wrong.

Maybe my computer just sucks at playing video, but the reference videos looked smoother to me than the 2x ones o_O

It should be about 60fps. The difference is pretty big once you see it. I seriously wonder if there are any ways to get around the sound issue.. Maybe do a custom player page that gets/streams the video feed from YT somehow. Save the video at 50% speed (no drops) and audio at 100%. Then use the custom player to load the video data + speed it up and audio straight.. And somehow mathematically count how to keep the audio track in sync with the video. That way YT would store the bulk content and some custom player hack would play it back with "60fps". Doesn't HTML5 kinda make it easier to "grab" the video as it doesn't use flash in between and relies on the browser to do the dirty work? Nice to see that my idea gathered some interest.

When i let the video load all the way first the 60hz play works flawlessly. If the video loads slower than 2x playback speed it sort of craps out when it nears the end of the loaded part. Using Chrome on win7 and modest hardware, and I must say that looked awesome. Oasiz I dont think an external hack is needed. Just some analysis: The audio doesn't sound incredibly different to me, just has some beating and slight but fast and consistently spaced chops to it. It also sounds exactly the same to me on multiple playbacks (I did not confirm this by recording and analyzing it up close though). It is relevant for anyone who can play the videso at 2x speed to report if this is also the case for them, or if each experience is widely different sounding. I'm not sure how to describe it but listen at normal speed to the slowed-down video. one particular example is the SMW keyhole entrance, how its a long smooth tone. If you open that in an audio program and timestretch it to normal speed it will be translated nicely. But the player is not doing a timestretch. It may be that the "correct" sound of the video can be created by taking the original audio at normal speed, splitting it every 1/59.97th second (one video-frame-length) and inserting a frame-length of silence after every split (or a duplicate of the split part), then overlaying this onto the half-speed 30fps video. In other words, taking ABCDEFG and turning it into A_B_C_D_E_F_G or AABBCCDDEEFFGG. I don't know enough about emulators or audio formats to know the specifics of how the tones in these half-speed videos were generated, but I suspect that's not exactly how the half-speed audio was made. Stretching out a sample or simply extending it smoothly results in something that sounds good played normally, but I mention all this because the sound, replayed at 2x, sounds to me like samples are being regularly dropped with some pattern... and the choppiness comes from newly-juxtaposed sample points not matching up. If you'll imagine a sine wave playing that has a period of X samples, removing 1/60th of a second or 1/30th of a second of samples from the sound to turn into double-speed might leave you with a splice at which the sine wave isn't at the same amplitude where the splice meets, and you get that clicking or beating sound. You're familiar with how this happens if you ever threw a sample into a slicer and chopped it into small parts and noticed clicks at the start and end of each slice. My apologies if this is bad information or not what's happening :( I am excited about your idea and felt the need to share this observation. I am hopeful that it is just a matter of figuring out exactly how the audio signal is being modified when you run the player at 2x speed; if this is done by a predictable and regular dropping of samples; if it happens the same in all browsers.

I have a quick and dirty method for syncing the audio whenever it desyncs. I just open the same video in a second tab and mute one of them. If the audio and video diverge again, I just do a little strategic pausing until the difference isn't noticeable. Works like a charm every time. Same procedure should apply here (you just need to mute the 60 fps video and open a 30 fps version in another tab).

http://www.youtube.com/watch?v=mcQxYId7GuM You mean like that DRybes? It should exclude 50% of the sound there, no "stretching". This is actually the video I originally posted that got the ball rolling, but the sound is even worse than the timestretched one I think. I am optimistic though that there might be some "magic number" that makes things sound even better. Sound for the sample clips does have slight choppiness to it, it is still there though. And yeah, that manual "open in tabs" way is another solution, the custom streamer solution would just make things tons easier as you'd just have to load one URL and it could autoplay etc.. :p But I guess youtube would block such things rather quickly.

This seems like overkill. We have downloadable encodes at 60fps already. The bad thing is you need a fast pc/internet in order to view the html5 properly at 2xspeed. The good news is once you have html5 enabled its much easier to view than a downloadable encode. Is it as good? No. But I would take 60fps/choppy sound over 30fps any day. More bad news of course is embedding or even viewing these n someones channel does not display the speed control.

Sucks that youtube can't allow 60 FPS videos. There are a lot of gaming videos on youtube, so it would be greatly appreciated. I guess they want to save space on their servers, but I think there are other ways that could be done, like suggesting people not to upload duplicate videos (similar to how Yahoo Answers reduces duplicate questions), or maybe having lossless encoding for low color content (TASes and emulator recordings), so that people don't have to encode them at 1080p for best quality. These 60 FPS hacks will probably also take more space than normal 60 FPS videos would.

Yea, I really like 60fps. But I had to switch it back to non-html5 because in html5 it can't load Original quality and I want it more than a couple of 60fps vids. (I'm using IE9 x64 Win7 x64)

I did my ownl trial run out of curiosity for this method. I have a preference for fighting and racing games so sharing 60fps videos has become a concern. http://www.youtube.com/watch?v=22UWCfFsRwY&html5=True Having to timestretch the sound for the purposes of the player makes it break somewhat if you listen closely (more noticeable with BGM playing) but it's not too bad. We really ought to push actual 60fps support on Youtube at the 480p and below levels at least.

how do I make YT vids go 2× speed? is HTML5 supposed to make that option appear? I’ve entered it, but still can’t see it

No audio and low quality, but you get the idea: http://www.youtube.com/watch?v=QK5VAiSzxFA&html5=True Edit: Here's a "45 fps" test (click 1.5x instead of 2.0x): http://www.youtube.com/watch?v=TryY-Bi4zIU&html5=True

Youtube apparently now officially supports 60fps video. This should make things a lot easier here, although a lot of the videos will need to be re-uploaded!

I was checking with "stats for nerds" with the 3 demo videos and none of them hit 60fps for me... unless i was too early then... hmm

Yup. It doesn't 60fps yet. Link to video That's a 1920x1080 video flickering between black and white every frame for 60fps. image proof:

Top is Windows bottom is MPC-HC (Media Player Center - Home Cinema) Also note the very first frame It's black. It goes black, white, black, white, black, white ... cont. And I was getting some fun sensations in my eyes...

https://www.youtube.com/watch?v=7SRTEXSpcyI right now, and looking at the Titanfall video, it seems like 60 fps is only available if you're loading the DASH streams (fmt 136, 137, 247, 248) 136 mp4 1280x720 137 mp4 1920x1080 247 webm 720p 248 webm 1080p on https://www.youtube.com/account_playback , selecting "I have a slow connection. Never play higher-quality video" will default to fmt 18 (mp4 360p) or 243 (webm 360p) I don't know if they will change 480p, 360p, 240p, or non-DASH formats to allow 60 fps YouTube's DASH has separate audio and video streams, and multiple segments of video that must be requested individually, YouTube's player will automatically switch resolutions in the middle of playback depending on how far the grey bar gets ahead of the red bar, or if the red bar completely gobbles up the grey bar.

This will not only be glorious when they enable support for more frame rates but also probably a detriment. It could mean my internet connection will no longer be suitable for watching 720p videos as more and more people upload 60fps videos and Youtube starts feeding me 60fps footage...
