3DPiP Question

[Sheeba]

Hi...

In 3dP in P, I would like the clip to arc up seamlessly as I make it spin from one key frame position to another. How do I do this? When I add a keyframe between to make it arc up....the clip stops there before moving on to the next keyframe.

I am not sure what you doing with the keyframes. For it to stop somewhere there has to be at least two keyframes that hold the same settings.

Could you make a screen capture of the 3DPIP window and share it with us? :)

The Arc movement will be tricky...
If you want the arc to happen between point A and B before moving to point C,
you must first locate Point A, then point B.
then move back on the timeline to establish points A1, A2, A3, etc before arriving at point B.

Unfortunately Edius does not use Spline movements with 3DPnP, so it may ultimately not work super-smoothly, but in 5 minutes, you'll know.

Rusty, are you sure about that one ? ...

3d PinP does have spline, but nothing advanced (eg. like After Effects velocity curves)...so doing a smooth arc is possible, but one that will not look "professional".

My (kinda) Bad

Interpolation is splined, but not movement.

Sorry for the confusion.

****! I thought I got you! :)

Still worth knowing though.

Thanks for comments. I took a picture of my screen but can't figure out how to get it onto this reply.
Here's what I have. Video of mountains. I want a 3d p in p to start at 0 scale behind the mountains. That's my A position. Then I set up B position....wanting the 3D p in P to spin up and over the mountain and end up about scale 60 in front of mountain...then it dissolves out after a few seconds. I could not get the 3D p in p to go up and over the mountain as it spun to position B. If I put a position keyframe between A and B to make it go up as it went to position B...it stopped there before continuing on to B. I want it to arc... but not to stop as it moves to position B.
I ended up not putting position A behind the mountain...but off screen to the upper left. But I wanted an arc over the mountain!

Also...I don't understand the spline stuff you're talking about.

Linear keyframes will be short sharp and exact. Like the ones you are using.

Spline keyframes will be smoother and will "undershoot" or "overshoot" its target befor reaching it. Basically, spline movement will smooth out the sharp corners and make an "arc" to some degree....but you don't have any controll over these splines in Edius. i.e. you can't controll how much "undershoot" or "overshoot" occurs.

As an example, try this:

1 Apply 3dPiP
2 keep size at 80
3 place a keyframe for position to the lower left of the screen
4 move forward 1 second
5 place a keyframe for position to the top middle of the screen
6 move forward 1 second
7 place a keyframe for position to the lower right of the screen
8 select all the keyframes and click the "linear" movement button (the diagnal looking strait line button) *note* The line inbetween all the keyframes should be broken. If not, click on each keyframe individually and then click linear button.

8 press play

NOW select all the keyframes and click the "spline" button to the right of the "linear" button. The far right one of the three.

Notice how the video gets slung arround, like its on an elastic path? and is smoother?

Thats what we mean :)

compare the two and notice the difference.

Thanks for tutorial. I understand spline and linear now. So the bottom line is I can make a little arch effect with the spline, but it's limited?

Exactly :)
