Parallax and Nested Zooms

[Michelle3431243914db]

Hi, I am a Vtuber and spend a lot of time moving elements in my video to make a 3D zoom composed of multiple objects. As you can already tell, every time I do a cinematic zoom, moving every element relative to the zoom becomes quite laborious. My question is: Is there a way to link the Scale function of various clips using a determined ratio? See the example below and the ratios of how different elements change with each zoom step:

• Character - Zoom step, scale increases +10%
• Chair - Zoom step, scale increases +5%
• Background - Zoom step, scale increases +1%
• For other videos I have a mic and an iPad - Zoom step, the scale increases by 15%

See the gif below to explain how it looks in one of my vids:

To dimension how laborious it is, I had to manually animate each 'Zoom in' for the character, chair, and background twice per zoom, that is, keying 10 different scale changes for 3 seconds of the video! I'm open to learning any way I can automate this (even if it requires scripting)

you can save Effect Presets, then drag and drop whenever/wherever you need them:

Create and save an effect preset

1. In a Timeline, select the clip that uses one or more effects with the settings that you want to save as a preset.
2. In the Effect Controls panel, select one or more effects you want to save. Ctrl-click (Windows), or Command-click (Mac OS) effects to select more than one.
3. Click the panel menu icon to the upper right of the Effect Controls panel to open the panel menu.
4. Choose Save Preset
5. In the Save Preset dialog box, specify a name for your preset. If desired, enter a description.
6. Select one of the following preset types. These types specify how Premiere Pro handles keyframes when you apply a preset to a target clip.

    

   Scale

   Scales the source keyframes proportionally to the length of the target clip. This action deletes any existing keyframes on the target clip.

    

   Anchor To In Point

   Retains the original distance from the clip In point to the first effect keyframe. If the first keyframe is 1 sec. from the In point of the source clip, this option adds the keyframe at 1 sec. from the In point of the target clip. This option also adds all other keyframes relative to that position, without any scaling.

    

   Anchor To Out Point

   Retains the original distance from the clip Out point to the last effect keyframe. If the last keyframe is 1 sec. from the Out point of the source clip, this option adds the keyframe at 1 sec. from the Out point of the target clip. This option also adds all other keyframes relative to that position, without any scaling.

7. Click OK.

Premiere Pro saves the selected effects, including their keyframes, to the new preset.
