In my tutorials, I have a rounded rectangular window built with three clips: webcam recordings of me talking on a green screen, the second clip for the background replacement and a png mask that gives the shape. It is a very common way for presenting tutorials. I would like to scale and move the rounded rectangle window around the screen using Transform effect. Is there a more efficient way of doing it besides moving one clip and repeatedly copy the transform to each other?

if i want to do that in the fast way (right now) is to use 2 different projects... the first with the rounded+clips at fullscreen...with green borders/angles..
from this create a rendering for example roundedbubble.mp4

on the second project place the rendering and move it everywhere with compositions/effects and a chromakey.

when you have to do changes ... just open first project and make changes looking at the times...

i know that this reduce quality of the "bubble" but if the "bubble" is not at full screen (but reduced) maybe can be ignored...
and if you don't want to use a seconday greenscreen with chromakey.. just create a complete custom shape using rotoscoping...

on my PC setup i have 2 screens (vertical layout) and i can have 2 Kdenlive sessions opened at the same time to work on similar things, to refersh the main project (to apply changes made on redering of first one) just save and reopen it... this reload roundedbubble.mp4

an example with rotoscoping: http://www.wcn.it/rotoscoping.jpg

(i know that this is a bit tricky... but right now i don't have any other idea)

I could also recommend using a composite and transform transition on your bottom clip, with whatever moves you need to make, and another composite between the top 2 clips, which you won't change. The second composite will apply to the 2nd track and move in the same way as the first composite does (i hope it's clear, i can clarify if needed)

Could you please clarify ? I could not get the point.

Hi! I made an image to show you: https://ibb.co/mG2VXWV
You should probably play around to really understand it though

Thank you. It is clear now.
