Urgent - editing circles within circles

It looks like this:

Change your active camera drop down to "active camera" or "camera 1," you're looking at a different view.

[PCC]

Thanks. Zoom is presumably what I want? Increasing the zoom pixels doesn't appear to be making an impact.

Hadn't set Point of Interest or Position, working now.

[PCC]

For the beginning frame, I can set the zoom to 5493532 pixels, but when I change it to 5493533 it disappears completely. It only goes as far as this:

You want to use the Track Z camera tool to move in for a more natural feel, not the zoom under camera options. Cycle to it using "c" and use the mouse to move in or out.

[PCC]

Hmm, I have the Track Z tool up but using the mouse to move in and out isn't working, it's just not doing anything.

It lets me squash and skew with the other tools, but zooming, nope.

[smrpix]

Even when this (yellowed) tool is the mouse icon?

[PCC]

Yep, nothing. Lol what motion is it - clicking or moving the mouse or clicking or dragging or what?

Must have been some weird glitch, cos I closed and opened AE and it's working now!

[PCC]

I can get both keyframes correct, but not at the same time. I'm trying to make it go from just inside the black circle all the way to 0% scale, but for some reason, everything in between the two frames is blank.

[smrpix]

Make sure you're not pushing the camera through the virtual plane, leaving keyframes with bezier interpolation can cause this to happen unintentionally.

[PCC]

Eeek, what do you mean?

[smrpix]

It means it's time to hit the books, grasshopper.

Here's what I handed in for the deadline.

I think I changed the keyframes to continuous bezier, which gives the slow down effect before each new ring comes into view. Want to sort that ideally.

[budwzr]

That came out nice. Did I get a credit? "Musical Director"?

I can definitely see that as some kind of lead-in to something larger than life. It begs a snappy quote at the end.

I don't know what Adobe means by "bezier", but it is a curve whose shape defines what occurs between its start/end points.

[PCC]

Ha, no sorry, no credit this time!

So... I still don't know what to do with the curves and the interpolation. I'm trying to remove that slow down completely, so it never lingers on one point and is a single continuous zoom out.

Bezier means a curve - there are handles that control the in and out velocities . It might slow down or speed up coming in or out of a keyframe. The rate of change isn't constant . Linear interpolation means a straight line between keyframes. So if the distances between points and keyframes were equidistant, that would give you perfect straight motion without slowing down or speeding up . ie. The time taken between points A=>B=>C=>D=>E...etc... would be identical . You would only need 2 keyframes in that scenario. But if the distance between layers isn't equidistant, the speed will not appear to be the same between layers, because even though the speed is the same, but the distance between layers isn't

In real life, very few things have perfect linear motion. Objects in real life tend to ease into motion, and slow down before coming to a stop . Linear motion tends to looks very mechanical or fake

So did they like your project ? A+ ?

Not sure yet, I'll let you know when I do.

What does altering the "Keyframe Velocity" do?

[PCC]

It seems to have been fixed just by changing all the keyframes to Auto Bezier.

[poisondeathray]

What does altering the "Keyframe Velocity" do?

It's not a "keyframe velocity" . They are position keyframes . The "empty" points between the keyframes are determined by the keyframe interpolation and shape of the graph

Velocity or average speed is just (change in distance) / (change in time)

It's basic math. For example, lets say the z-axis . If you have a position keyframe for an object at position zero, at time zero ; and another keyframe at position 1000 at time two seconds, and the interpolation between those keyframes is set to linear, the speed would be change in position / change in time

speed = (1000-0) / (2-0) = 500 units/second

It seems to have been fixed just by changing all the keyframes to Auto Bezier.

Maybe you lucked out

You can read more about keyframes when you have more time ; there are lots of free tutorials and online resources

Keyframe Velocity was an option in AE. I understand what you mean.

Hopefully, I'm rendering it now.

Thanks for all the help everyone, got it exactly as I wanted in the end!

OK. Glad I could solve your problem
