Adding Video Transition moves keyframe

I don't think this is a bug so much but I need to figure out how this can be fixed.

I am putting together a slideshow and I am doing the "ken burns" type of of effect. So, The picture is in there at 3 seconds. I create keyframes at the beginning and end of the picture showing movement or zoom.

Then after I have them strung together, I select them all and "ctrl-d" to apply the default Cross-Disolve transition.

At that point the keyframes jump in several frames. Then I have to go to each photo and select with the mouse and move them to the edges! It is SO SLOW. And I have like 200 photos to do this with. I have pictures before and after. How can I prevent these keyframes from shifting when I apply the transition?

The reason I do not do key frames after the transition is because the picture is not visible at the beginning and end due to the transition.

So, really, the problem for you is that PP does not move the keyframes, just the opposite of the thread title. And it would be a bit presumptuous for PP to move your keyframes.

While this is the correct answer. it doesn't help me when I have 400+ images in a slideshow and I have to slide the darn keyframes to the edges on each picture. It is slow and annoying. I don't recall ever having to do this with previous versions but the last two years I have had to do this. It is frustrating.

Add the transition first then keyframe on the edge of the transition so you can see what you are doing, then move the keyframe to the end of the transition.

And even further, the clip/picture is extended by the length of your transitions. So, if you use a default transition of 1 second, on a 5 second clip, you've keyframed your clips for 5 seconds but your clip now is really 6 seconds long when you apply (add) the transition, but you put the keyframes 5 seconds apart. I hope that's clear? 🙂

On further looking at it. PP is not moving your keyframes. It's just an indication that your pictures have handles (extra frames) to get it to the end of the transition. You can see the slightly shaded line to indicate the clip/picture you are on.

Yes, that is sort of what I realized last night that it wasn't necessarily moving the keys. When I apply the disolve first, I cannot see the photo when I'm attempting to set the start and finish since I am at the end or near the end of the dissolve when doing it. So, I end up setting the start and finish inside and them moving them to the edges anyway just like if I did it in reverse order.

I guess there is no way to really deal with this. I'm surprised nobody else has complained or perhaps even noticed that it make slideshows look bad.

I see the same thing. I suggest you change your workflow so you apply the dissolves first then create the keyframes.

So then you can set the keyframes after you add the dissolves.

Anyway, PP is just giving you handles so your dissolve has behind frames so the dissolve works. Notice the difference between the keyframes between dissolves and the one with the fade up from black (first one)

Not sure I understand what you mean. This is my process:

Select picture, click in effects panel and tap "home" (I believe, my keyboard here at work is different) and it pops to the beginning of the picture.
I set the zoom and position.
I click 'end' and that pops to the end and I set the zoom and position.
I move on to the next picture and so on.
Then I select the series of pictures and "ctrl-d" to apply "Cross Dissolve". Then the keyframes appear as my original post's keyframes.png.

If I play the slideshow from this point, what happens is during the transition, the movement of the photos stops so there is this strange stopping that happens as the transition happens between the two photos. It looks jankie.

So, then I have to visit each photo and drag the key frames to the edges as shown in the keyframes2.png file. Then when I play the slideshow, it is smooth.

<<the picture is not visible>> Is it a fade in/out to black? Or a dissolve to the next picture?

It is disolve to the next picture.
