I've searched for this and I don't think it's possible, but I have to ask.

I use a bunch of stills as filler in places and I often put some kind of in point and out point transition. Since they're used as fillers, sometimes I have to stretch or shrink their time. Easy enough, but the @#$& keyframes don't move. So, I kill time dragging the keyframes back to their new location. I don't want a time stretch since I'm not looking for a relative recalculation of the key frames. I'm simply making them longer or shorter.

Is there a way to move an out or in point and have the keyframes move?

Now, I usually trim the outpoint and move the layer to the right place since moving it keeps the in point keyframes in place.

Who says you have to do a time stretch for the entire clip?

Use Time Remapping to lengthen & shorten the static sections of the clips, getting them to the proper duration. It takes a little planning, but you easily can do it.

you could use stretch (either form the timeline stretch property column or layer>time>time stretch) to change the duration, which will also stretch the timing of the transition.

or you could use an expression to trigger the transition based on the in and out points of the layer. something like this would work for opacity:

dur = 2; // duration of transition in seconds
if (time > outPoint-dur){
100 * (outPoint - time) / dur
}else{
100 * (time - inPoint) / dur
}

just set the duration you want for the fade in/out and the expression will accommodate any layer duration (well, it probably needs to be long enough for both the fade in and out)

sorry, i should have read your post more carefully, you don't want stretch....

Hi Dave & Kevin,

Your're right. Stretch affects the fade-in and out proportionally. I'd want to keep the 2 second fade regardless. Which, of course, I'd wouldn't trim the layer so much as to make the fades cross over.

It's just that I was editing a screen capture of a software demo that I put a lot of stills in and was cursing all the keyframes I had to move :)

The expression idea would work moving forward. Or create preset...
