Premiere Pro: Is there a way to "lock" keyframes to a clip

i hope i might not be late for this but i got the solution , but first here is an example first . lets say  i have clip for 24 frame  and i in and out effect for first 1 frame ( in ) and 5 the frame ( out ), i made a preset of it but then i have to use the same present on 42 frame clip which is double of the original . now apllying the clip would increase the lenght of the original key frame which was 1stframe (in) 5th ( out ) frame but now it will become 1 st frame ( in ) and 10 th frame ( out ) . if you want your preset to work the same duration as always regardless of the clip duration , whenever saving the preset , change the type to anchor to left . the duration of key frames always remain the same . for more info you can watch this video

Since everyone provided valuable options to approach this much easirer, I would assume that you are working with keyframes for a specific purpose.

@Justin Taylor-Hyper Brew was thinking in the right direction when he mentioned presets, However choosing "Scale" will cause your keyframes to stretch on longer clips and your fade-in and fade-out will become longer.

Instead, you should create 2 seperate presets one for the fade in only with "Anchor to in point" and the other for the fade out only with "Anchor to out point. Both presets should be applied

Hi!

you design one of the text clips as you want, then mark and copy it by ctrl+c, mark all the other text layers and  choose 'paste attributes' (you can also assign a shortcut key for it).

In the dialoge box, choose the parameters you would like to copy and notice you check 'scale attributes times' (the first parameter)!

That should fit your animation to the length of the clip (by the relative precentage of the length of the original animation from the length of the original clip).

Good luck 🙂

These answers don't fit my need, but I have the same question. I have a massive panoramic image that I'm using as a motion graphic in a square video.  I'm using keyframes as a step-by-step process through the image.  I want to adjust the intro to the motion graphic and need to push it back several frames.  However, if I do, I will lose my keyframes.  I have 40+ at this point on the clip.  How do I lock these in place, so that I can adjust other clips in my sequence without losing my keyframes?  I can't afford to lose them at this point.

I found this link helpful. before watching this I didn't know about the responsive design-text feature in Premiere pro https://www.youtube.com/watch?v=Si3xljs7GYI

As you have discovered, keyframes do not change when the clip that hosts them has a duration change.

The easiest way to do what you want is to build your graphic with Essential Graphics and use the "Responsive Design -Time" feature of Essential Graphics:

which will let you set Intro and Outro durations that will remain constant even when the overall duration of the clip changes.

Alt drag text box from the timeline into a in depended text box on the timeline.

You have 3 options for this.

1. Transitions: Instead of opacity keyframes, add cross-dissolve transitions to the start and end of the clip, now when you stretch your text they will stay the same length.

2. Preset: Once you're done animating your fade with keyframes, right click the opacity effect and "Save Preset". Under settings choose "Scale". Now when you apply your preset to a new clip, it will scale the keyframes to the duration of the clip.

3. Essential Graphics Templates: You can basically set up protected in/out regions on text templates. Premiere Gal has a good tutorial on this.

Hope that helps.
