How was this slow motion done

I don't know if you have seen the video I'm going to refer to but it's a youtube video of someone demonstrating the various FOV of the Hero 2. However this is not a FOV question. In that video, he was demonstrating slow motion, by showing some juggling. The video was playing at normal speed and he said, "now this is slow motion" and the video switched to slow-motion without stopping the video or pressing any buttons. It was a seemless transition to slow motion from normal speed.

I know this was done in video editing software. But I'm not sure how this is done. Or if it required some special video software.

The way I can invision this being done is to film the entire juggling, at 120fps (4x). Then when you play it back at 30fps, it's 1/4 speed. However that would produce an entire video in slow-motion and not one in which the first part was normal speed and the second part was slow-motion.

Since this was done in one video, I suspect the software used had some way of playing the source at 120fps and recording the output at 30fps, for the first part of the video and then for the 2nd part of the video (the slow motion part), the source was played at 30fps and recorded to the same file as 30fps. This would give the effect.

1) Would this effect require some special software?
2) Does most video editing software have this capability?
3) If you know of software that does this, what would that software be?

Here is the video:
Any idea how he switched from normal speed to slow-motion without any glitches or obvious splicing (in fact, I doubt this was two seperate videos. It was too seamless).

I'm not going out to buy a $1500 package so I"m hoping this is a common video technique, that lower priced software might have. I've been looking at the Corel VideoStudio Pro X5, but my trial has expired so I can't see if it will do this.

Any idea how this was done? Here is the video:

Hi, i think I know what your

Hi, i think I know what your trying to ask..

Baically the clip of him juggling is playing, then it switches to slow motion smoothly?

Is an extremley easy technique. I use Cyberlink Power Director 10, about 60 quid.

You place the clip you want on the time line. Play it and as soon as it gets to the part you want to slow-mo, pause it. Then 'split it'. It will then cut it half, then you simply click on 'power tools' and slow it down to the desired speed. Hope this helps

I tried the "split" and it

I tried the "split" and it works exactly as you say. And it's very easy. I have the trial version of Director 10 and a registered version of Corel Video Studio Pro X5. I'm trying to decide if I want to register Director 10 also. Both are high rated programs. I'm using Corel, because that's what I've been using since they acquired PSP.

Thanks for the advice.

you can do that in sony vegas

you can do that in sony vegas pro with the event-velocity (tutorial: http://www.youtube.com/watch?v=mnZHKXolqC4( or in after effects with twixtor (with keyframing the speed) or with the time-reverse-layer!
