keyframe fill

[Mike Clasby]

No not really. You can do it but not in one step (as far as I know). Just curious as to why you would want to do that. Do you want all of the keyframes? Why?

Do you want only a few of the “tween” keyframes, you can do that. Just move to where in the timeline you want the “tween” keyframes and click on the “Add or Remove Keyframe at Current Time” box, the place that has the check mark when you are on a keyframe.

Anyway you could add a keyframe at all the “tweens”, by starting at the first keyframe, hitting “Page Down”, then clicking on that box, “Page Down” + click on box, etc, etc…

If you can make your animation with an expression you can convert those to keyframes at every frame with Animation>Keyframe Assistant>Convert Expression to Keyframes.

thanks for the answer, but yeah when I’m working with cams if I’m focus on something and them move the time line and put the focus of the cam in another place the first key frame seen to take the cam out of its first focus project, i thought it because of the motion of the 2nd key the camera position it self in a better way to move to the 2nd key frame.. so i want to add all the key frame in between to change each little by little until the camera animation move to the 2nd point with out losing the focus of the first.
but i guess manual job will have to do.

OK, I don’t fully understand what you’re trying to do, but that’s me because I don’t use AE cameras that much, but I did think of a way to get all those keyframes relatively easily.

Make a new Solid (I used 30×30), “P” reveals Position, Alt click the Solid’s Position Stopwatch, then pickwhip (looks like “@”, middle little box when you add expression) to the Camera’s Position, to get an expression like this:

thisComp.layer(“Camera 1”).position

This just tells the solid to use the camera’s position as it’s position. If we convert that expression to keyframes, we have what you want.

Now, highlight that expression, the “Position” next to the equal sign, and then, Animation>Keyframes Assistant>Convert Expression to Keyframes. Now you have all the keyframes for that move and you can Copy/paste them back into the camera’s position if you want them there.

——————————–

Here are two methods to keep the “Focus Distance” of the camera the same as the distance from the camera to the object it’s looking at. Is that what your trying to do?

I think the second method, Dan’s is more Universal, works for all cases, but I haven’t really checked them out in a project.

1) Andrew’s “Create a 3D Room with Cool Title”, camera focus stuff starting at 5 1/2 minutes:

2) Here is another way, more accurate in some instances:

hey mike thats a great tip, but my real problem was that i wasn’t using the point of interest so the can can move easily. i was just using position.
but i be using that tip you just gave me.
