Bouncy Ball Sing Along
Hi,
I need to create a ‘Disney’ sing along type video where a bouncy ball follows along song lyrics at the bottom of the screen…
Is there a smart way to do this?
I’m thinking I will precomp the lyrics line by line and have them scroll up behind a mask, then do the ball as a second comp..Any ideas???

I can tell you that using audio preview (numpad .) and setting layer markers (numpad *) is a great way to mark out where the ‘ball’ should be bouncing on the text. The timing is more than half the fight!

I tried your suggestion, but I dont see any markers appearing.. is there a way to enable them? Pressing * on the numpad didn’t seem to do anything…
thanks.

Oh, silly me, you need to have the layer that you’re adding the markers to selected.

Got it!
Thanks!!

This is how I’ve done it:
Make a null bounce up and down one – at the sp[eed you want it to bounce.
– Add a looping expression to the null’s position property: loopOut(type=”cycle”)
– Make the ball layer a child of the null.
– Animate the ball from Left to right. position it so that when the null comes down, the ball is on the text.

Well if your tempo changes you can use a new ball and null.
I saw someone do an expression that used a Sine formula – it made things go in one direction and then the opposite at whatever speed you wanted – you could probably use that in conjunction with an expression control slider to increase or decrease the tempo – but that’s a bit beyond my personal skillset.

By the way, Dave – I mean to say – GOOD POINT!

frequency = 1;
amplitude = 10;amplitude * Math.sin(time * frequency * 2 * Math.PI);
This will give you values oscillating between
amplitudeand-amplitude,frequencytimes per second. You could definitely attach the frequency to a slider.However, in my experience doing sing-a-longs I expect that there are generally too many changes in tempo to hit the lyrics accurately with this method. Feel free to give it a shot though =)

I read that a bit too quickly the first time, missing one letter of the last word. I thought you meant that it was too big for your frying pan. LOL.

here’s a thread with a few other methods from several months ago….
in my response to the post i had included an expression that would generate the movement, but used keyframes for hit/bounce position and timing, so the frequency was completely adjustable for every word…
