Awesome, thx for the detailed answer. I had tried the second method but I had missed the last step and couldn't see the effect. Now it works, this will save me a lot of time!

<p>I am trying to animate a series of drawings. I have 10 drawings of 10 states of an object and I would like to have a crossfade between each states and this repeated for about 2 min back and forth.</p>

<p>I am using After effects and I have imported the image sequence, made a composition (30fps, 2 min long) changed the time remapping so each drawing is displayed during 15 frames (0.5 seconds). </p>

# repeat crossfade in a sequence of images

(Asked by: username_0 on 2015-02-22)

I am trying to animate a series of drawings. I have 10 drawings of 10 states of an object and I would like to have a crossfade between each states and this repeated for about 2 min back and forth.

I am using After effects and I have imported the image sequence, made a composition (30fps, 2 min long) changed the time remapping so each drawing is displayed during 15 frames (0.5 seconds).

My issue is that the change between drawings snaps and I need a crossfade between them. The other option I can think of to is create a composition with all the drawings and manualy create key images for opacity but this is going to be very long as it has to go on for 2 minutes.

Is there a way to crossfade each drawing into the next one in Affter effects?

There's always more than one way to do things in AE:

**Method1**

Import the drawings as separate source files, rather than as an image sequence (in the import dialog uncheck the image sequence checkbox). Once you've got all your images imported select them all and drag them into a new composition.

They will appear as a stack of layers with only the top layer visible, but don't fret. Next step is to trim them to the length you need. The easiest way to do this is to select them all and move the playhead to the last frame you want (frame 15 in your case) and hit `alt/option``]` which is the shortcut for trimming the end of a layer.

Now right click one of the selected layers and from the contextual menu choose **Keyframe Assistant > Sequence Layers…**. To get a crossfade you need to check the overlap box, and use the **Dissolve Front Layer** transition (I have never been able to work out why you would *ever* use the **Dissolve front and back layers** option, because it means that halfway through both layers will be 50% transparent, meaning that the background will show through). You might have to go back and add extra frames to your layers to allow for the overlap, so if you want a 5 frame overlap on a 15 frame layer you'll need to make it 20 frames.

**Method 2**

Do what you're doing, but make sure that frame blending is turned on for your image sequences. It's the little filmstrip icon in the switches column (you may have to hit `f4` to toggle the visibility.
