I never thought 60 fps was possible

Something I found strange about a recent Mother 3 translation update on youtube http://youtube.com/watch?v=ABczoJJQS34&feature=related
...It was the fact that 60 frames per second was somehow encoded. I thought that doing so was impossible with codecs (especially on youtube, saying as they often down convert to make it playable). Am I wrong to assume it's not possible? If so, what codec(s) do you use to do that?

Obviously, since you just proved that it IS possible.

PLEASE reread what you've typed before you hit the post button, so you don't end up looking like you don't know your ass from a hole in the ground because you worded a legitimate question stupidly.

I don't know where you heard that, but US Digital Broadcasts (which use form of MPEG2 ) can output in 720p (and 1080i) if they want provided the media is capable. My point is that 720p is equal to 1280px by 720px at 60 refreshes per second or what you thought was impossible, is possible. Not to mention 1080p video on BluRay or Digital Media Files.

you can record in x fps and playback at y.

Indeed.

ATSC actually spec'ed 1080p as well, but it can't be broadcast at more than 30 FPS due to bandwidth restrictions on the channels.

Of course, 1080p/60 is still an actual part of the spec, unlike progressive-scan NTSC.

what I should have said is, "i thought it wasn't possible to encode in 60 fps, so, how the crap do people encode it that way" Sorry for not clarifying that better.

it's possible to encode in any fps you like even 160.

How do you see that?

As being very smooth and not 24/30 fps.

funkyass · Post by **funkyass** » Fri Jul 11, 2008 5:03 am

based on what?

Oh, I think you mean that youtube had encoded some videos on 60 fps, when usually it seems to reduce it to economize filesize.

leilei · Post by **leilei** » Fri Jul 11, 2008 7:57 am

youtube doesn't touch direct .flv uploads, so the uploader who did it encoded it to flv himself

That might explain why it's 60 fps...
