Check out the smooth slow-motion video playback found on Sharp's newest smartphones
Sharp has three handsets that will trick your phone into thinking that it has captured video at 2100fps. When you record at that speed and then play it back at a slower rate, the result is a slow motion effect. The smoothest looking slow motion comes at a playback speed of 60fps or 120fps. But at those speeds you can't slow the original footage down as much as you would like. But Sharp has developed a solution that produces the optimal number of frames for smooth slow-mo.

By adding extra copies of some of the frames and using some additional post-processing magic, Sharp is able to allow owners of just announced models like the Sharp Aquos Zeta, Sharp Aquos Xx and Sharp Aquos Serie, to wow and amaze their friends with slow motion like you see in the video at the bottom of this story.

The three handsets record 210fps at a resolution of 854 x 480, or 120fps at 1920 x 1080. By copying 10 frames for each one captured by the camera, Sharp can produce video at 2100fps (in FWVGA) or at 1200fps (in FHD). All three models will soon be available from Japanese carriers like DoCoMo, SofBank and KDDI.

At a press conference in Tokyo yesterday, Sharp unveiled the three phones along with a lightweight 7-inch Android powered slate called the Sharp Aquos Pad SH-05G. Weighing in at only 213 grams, the slate offers an IGZO display with a resolution of 1200 x 1920 and a 3900mAh battery. With an 8MP camera that faces outward, the 8mm thick tablet will be available from DoCoMo in July.

Despite holding the press conference and introducing the three new phones, there is talk that Sharp is looking to exit the smartphone business and would do so if it could find a buyer.

Even 1080p @ 120 fps is amazing.

you honestly call that "smooth"....? maybe its my internet connection... but this is no where near as smooth as my 240fps ip6.

Video is 480p thats why

Title says "check out smooth slow mo.." Comment says "you..call that smooth?" Put the two together. Not rocket science.

But its 2100fps so how can 240fps be smoother than 2100fps?

don't be stupid, it's like retina being clearer than QHD.

Your failed sense of sarcasm also provides me with more reason to believe you live under a rock

its youtube! youtube only has videos at @30fps or at 60 max.

It's your connection. It was totally smooth on my end.

oh ok. totally credible coming from you, lololol.

yes i'm sure it your connection. Because youtube video would drop the fps if there is connection problem. LOL

LOL so youtube video with slow internet connection could just look less smooth? smh, you should know if it buffering problem or not, no need to go as far to compare it with your mighty iphone.

Mad??

Is it just me and crappy eyes, or is the video not in focus?

When you do software interpolation of 120fps into 1200fps your going to "blur" 90% of frames to morph them into the next real frame. Assuming that is what they're doing. Makes for a smooth but not so accurate slow-mo because most of what you see is interpolated.

It would probably look much sharper if the object they shot maintained its shape the whole time, or at least had high contrast edges so that it was easier to track the speed and direction of each pixel.

If it's true they're looking for a buyer I really hope so this is Samsung. Devices from sharp are gorgeous, but lack the global distribution that Sammy could provide. As for the tech, both have made a different aproach, is valid and work for them.

I imagine Google could build this type of image calculation into the VP9 codec to "render" additional interpolated frames when desired in order to slow down motion. I assume it's already doing vectorization pixel tracking.

That honestly doesn't look very good.

wow that's amazing really

This looks cool, but I think they're missing the point of slowing down an object being affected by another force - I like making slo-mo videos to watch how the object actually interact when they break or bounce or erupt etc - it's to see what our eyes cannot... This is like watching CGI - really cool, but u know its fake.

Here is better video in 1200fps shot https://www.youtube.com/watch?v=WRUH8JiLcQk

The video is at 360p, this probably isn't the video quality the original is. If they're showing a 2100 fps in a 30 fps *360p* you have to expect a sh*tload of quality will be lost. They use a sort of overlay technique, of go to their sharps web page to see if they have a more accurate video. Also, let's assume our phone's are able to run 1200/260 fps to begin with.

but if it only repeats the same shots that's totally lame!
