I suppose in some of those sports videos like basketball, volleyball, baseball, soccer... any of the sports that use round playing objects. You might be able use it there somewhere? On the music side, maybe a spinning CD/DVD, long playing 33 1/3 vinyl albums? Gambling stuff... Wheel of Fortune, roulette wheel? There is Probably lots more.

Excellent use Tom! It was very smooth too. The other example I gave in Vol. 1 was a grandfather clock, the little pendulum swinging deal, which I called a bell for some reason! Actually, you could use the same kind of effect in Vol. 1 for Bell, but I said it in relation to clock. Glad to see I now have the wheels turning in people heads, no pun intended!

Okay, you asked for it.

This is the first tutorial I've ever done in my life so please bear with my simplicity/stupidity :-)

First thing I did a search for a picture of a clock on the Internet where I can get as much of a "straight on"/square view as possible.

I then ended up cutting out both the big hand and the little hand. I only use the big hand in this example. I then cleaned up the face clock with no hands.

The sample file runs 100 seconds... 10 seconds of the spinning clock and 45 seconds each of the important screens.

I only use 2 layers... face clock with the layers extracted and the big hand. The face clock with the layers extracted has absolutely no motion or adjustments. It sits square in the middle of the screen in "fit to frame" mode. Screen capture wasn't included because really nothing to show. It is the bottom layer.

The top layer is the big hand. The first really big issue here is to try to find the center of rotation which is off center. In my instance, it was approximately at 43 x 41. I found out by trial and error... no magic at all involved. Just a PITA to have to fool with it. Basically you're trying to get it as close to dead center of the clock face below.

The other areas of importance, I have highlighted with a red arrow on this slide.

The next slide is the screen of the rotation modifier. It is the sawtooth wave as Rick illustrated in his tutorial. You can speed up/slow down the speed of rotation by adjusting the frequency. You will note my other settings... similar to Rick's.

With a little more effort, one could add the little hand... obviously with a significantly slower rotation.

From my perspective the practical ways to use something like this in a video are as follows:

1. Some videos that I've done require illustrating the concept of "passage of time" in pictures. I would use a very high spinning clock to demonstrate this concept.

2. There may be others where you want to document a specific time passage... say, 8:00 PM -11:00 PM (a wedding rehearsal party, etc.) It would work nice there.

It's interesting to note in this example that the use of a modifier is critical to it's success. Others have noted that you could do all of this just using keyframes/multiple frames which is true. But, and this is the BIG BUT, the location of the off-center rotation becomes absolutely critical. You must be dead on with this because it doesn't take too long before the big hand flies off the center of rotation in a noticeable fashion using the multiple frames/keyframes approach.. I didn't realize this until a couple of hours ago when I was playing with it. So the choice is yours... drive yourself crazy trying to find the exact point of the off-center rotation or use modifiers and get reasonably close.

So there you have it... I'm not sure I can explain it any better because I barely understand what I'm doing in the first place.

Hi Rick,

Well that didn't work either, I think my Producer is broken when it comes to that modifier!! cheers Jan

Vol. 4 is going to cover it. Stay tuned! My work is suffering as my mind is wandering through all this stuff! :roll:

I think Rick must've put a spell on me in the last couple of days :-) Here's another idea for using modifiers. This time it is the X -Zoom and Y-Zoom. Size your heart.png file accordingly. There is absolutely no motion from start to end, BUT you need to:

Set both your X-Zoom modifier and your Y-Zoom modifier to

Amount based on function = Sine Wave

Frequency = 2.0

Amplitude = 10.0

Phase = 0

and finally, slide timing to whatever you want. I used 10 seconds.

This one should work for a Valentine's Day video :-)

Another concept that I discovered this morning from watching Rick's tutorials. You will notice that most of his examples involve a single slide. It crossed my mind that after you've created some sort of modifier effect in a single slide it can then be converted into a Slide Style. It works! The original image in your modifier slide you created is not retained as part of the slide style which means that you can apply the modifier effects to any single slide you wish.

In working with the Vol. 4 tutorial (in production), your right, I gave you bad stuff. I thought it should have been that simple. Ultimately it is but it's also a bit twisted. Once I show it to you then you should be well on your way.

It's funny, you would think that would be the easy one. I have understood all the other stuff and once I get the movement one I am going to do a show. I can see so many uses for this actually and you are an absolute doll to do all these tutorials!! off to the day job......cheers Jan

Funny that some one mentioned clocks. Had been thinking of this one myself. If you could put one in a slide to show the passing of time.

Anyway, found a clock photo with a pendulum on the internet. Moved the pendulum to a seperate file and add a second hand.

The pendulum swings via a modifier to the rotation. Sine wave.

The second hand was a little tricky. Of course I could rotate it smoothly, but I wanted to apply a certain jerkyness to the appearance, so it would appear normally.

Anyway, here is my take on a clock.

I also applied a Hue modifier in attempt to change the background color in time with the clock in order to add drama.

Great use of modifiers in the clock! The background should have switched right on the tick, which made me wonder if you set it that way and then it went out of sync when you uploaded it. I mention this because I had a problem with a recent show done in version 4. Uploaded it twice, and twice it was out of sync. I gave up and made it into an EXE, which had perfect timing.

Modifiers are like having a shiny new toy, aren't they?

Nice job Cliff

Did you happen to make the movement in the second hand a function of the movement of the big hand? That is, for every 360° that the big hand moves, the little hand moves 360/60 = 6°. I think that should be doable although I haven't tried it yet.
