View Full Version : super slo-mo clips from the AJKC -- hardware specs?

By now, many of you have probably watched and enjoyed the super slo-mo videos from last month's AJKC. One of my faves happens to be this ippon by Uchimura.

It got me thinking, what kind of hardware do you need to produce these super cool, super slo-mo videos? I mean, you gotta have that super slo-mo camera running the whole time, right? And I assume it's captured digitally. Gotta be some mondo big files we're talking about. Do they dump them onto a monster hard drive as they're being captured? And what kind of cameras are we talking about anyway?

Also, the fact that the ZNKR uploaded these super slo-mo clips for the first time this year (with the exception of that super slo-mo documentary from last year) leads me to think there may have been some technological breakthrough that allows for this -- or at least makes it practically feasible now. Inquiring minds want to know.

The video comments say that it was shot using a Casio EX-F1.

I happen to have one of those cameras, although I haven't used it to show slow-mo of shiai. So happens that the shiai movies that I posted to youtube last year (?) were shot with it, but at full speed. Space is a problem, but there is a mode on the camera where you can switch between 30 fps (normal) and 300 fps by turning a ring on the lens barrel. So, you can shoot the whole time and slow-mo only the action. That'll help a little with the space, anyway. Somehow those movies look slower to me than 300 fps, but it could just be my imagination. Like I said, I don't have any experience shooting slow-mo video of shiai yet so maybe my judgement is off.

Most video editing software should allow you to add slowmotion. Of course, the quality would still depend on the quality of the camera used.

Sure, but these are super slo-mo videos, which have to be shot at a higher frame rate to begin with.

I see, my bad ^^"

Also Video-editing software uses a form of interpolation to create the slo motion "effect." :)

Yeah, but it looks like crap. These videos are shot at high speed, no doubt about it.

LOL that what i meant to say, but was too chickenshit to say it ^_^ +rep to you

that link that video that showed Teremoto beating Takanbe by a fraction of a second...anyone know what camera speed that was shot at? It must have been more than 300 fps.

A quick search for that camera and its spec sheet noted that it would shoot at 300, 600, and 1200 FPS. Thats fast, but the faster it shoots the smaller the picture is, as in raster to raster size. THat looks like it was 300 fps . I downloaded the clip and sped up a ten secon section by 1000 percent. and it rendered out to about 1 second. Usual video at 30 frames a second should make that about right. I am pretty sure, man i suck at math. Regardless those are awesome shots.
