animating 200 fotos at once

[Simon Bonner]

It depends what you want to do, but there are two tools you might make use of. One possibility is to import a folder of your images as an image sequence. Then each image will be one frame. With a bit of maths you could then time remap the layer so that each images lasts longer than a single frame. Another thing you could do is set the still duration to 2 seconds, import your images, then place them all into a comp. Then use the sequence layers function. I could explain how this works, but it’s probably (well, definitely) easier for you to check your help files for “To arrange layers as a sequence”.

Sequence layers with the Animation>Keyframe Assistant, and add two expressions.

Here you go:

1) Add the layers to your comp.

2) Trim to the desired length by going down the timeline (2 Sec?) and selecting all, then, Alt ].

3) Select the layers (top down if you want the top one first), then, Animation>Keyframe Assistant>Sequence Layers, then uncheck the “Overlap”. That should sequence them (see “A”, below if you want the layers to overlap)

4) Add the following expression to the layer’s Scale (Copy the Expression, Alt-Click the Scale Stopwatch, Paste):

ScaleInTime = 0.5; // fade in time (seconds)
minScale = 90;
maxScale = 100;

s = linear(time,inPoint,inPoint + ScaleInTime,minScale,maxScale);
[s,s]

Set ScaleinTimem, inScale, maxScale to whatever you want.

5) Now add this expression (we’re almost home) to the layer’s Opacity (T reveals, Alt Click the Opacity Stopwatch this time):

fadeOutTime = 0.5; // fade in time (seconds)
linear(time,outPoint – fadeOutTime,outPoint,100,0)

OK, that’s for one layer, So select both expressions, then Edit>Copy Expression only.

Now select all 199 other layers and Paste.

Or can also make an animation preset out of the opacity and scale expressions for mass application.

That should do it.

“A” – If by “Is there a way to push every still by 2 seconds further than the last?” you meant to literally overlap by 2 sec, try dragging all 200 onto the “Create A New Composition Button” (in the Project Window, between the garbage can and the folder) then you get a dialog box with lots of options for sequencing and other stuff. You can then use that as a precomp, or change the comp settings as need (Ctrl K).

Next week you should be able to do a mass swap, by selecting the 200 layers in the timeline, then Alt-Drag the 200 new photos from the Project Window onto them.

Hmmm… That part sounds too easy.

Enjoy.
