quick way to add a disolve i.e. opacity
I’ve used AE since v3 and I’ll admit I’m a skim user, i.e. I barely use most of the power of AE. But I got to get work done ya know. I find myself doing a lot of opacity 0 to 100 or vice versa keyframes. (auto dealer commercials) What’s a quick short cut I can do to add a 10 frame opacity change without going through the motions of inserting those two keyframes and changing the value. I’m sure there’s an easier way. thanks.

You have a couple of options that I know of –there may be others. You can use keyboard shortcuts to make it faster. Select desired layer, hit “i” to go to the in point. Hit Alt + Shift + T to set an opacity keyframe. Set the percentage to “0”. Hit Cmd + Shift + Arrow to shift 10 frames down the timeline. Hit Alt + Shift + T to set another opacity keyframe. Done.
Or, when you are done doing that, you can select the opacity parameter and go to Animation > Save Animation Preset and save the fade as “10 frame fade up” or something like that. Then whenever you need a fade up you can drag your preset into the comp window or onto your layer. Make sure your timeline indicator is at the position you want the fade to start.

there are 3 easy ways i can think of…
if you just need to sequence several clips or images and have the ready to go (clips trimmed, image cropped etc) bring them into ae, then drag them all on the make comp icon, choose single comp, still duration (if needed), sequence layers, 10 frame overlap and dissolve front layer. make sure when you select your clips/image, you select them in the order you want them to appear.
you can do a very similar thing if the images/clips are already in a comp by trimming each layer to the length needed (they don’t need to be the same length), then select each layer in the order that you want them to appear, then choose animation>keyframe assistant>sequence layers and choose overlap, duration, and dissolve front to layer.
if neither of those options work for you, you can use an expression like this for opacity:
timeToFrames(time-inPoint)*10once you have that set for one layer you can choose edit>copy expression only, then select any other layers that you want and choose edit>paste. even better may be to create an animation preset… select the opacity property for the layer that has the expression, then choose animation>save animation preset. now you can apply it any time you need it to any selected layers from effects & presets panel (just start typing the name, like ’10 frame dissolve’ and it will pop up).

Just discovered one more way. There is actually a “Fade In+Out” effect. It allows you to set the # of frames for the fade.

I’m missing the part where I can set how many frames to fade out.
I’m trying to set a preset to fade out to Opacity 0 during the last 7 frames.
I’ve tried doing this in the time line and saving the Animation preset but it didn’t do anything when I tried it again
