SUMMARY
Hello,
for the past few versions, there's been an issue with Composite & Transform,
when using multiple tracks with compositions between them and zooming in or
out. It might also be a problem with an interaction with Transform? I'm not
sure when it started, and i'm not sure if it's a Windows only issue or not, and
I tried to do some testing on both Linux and Windows but ran into issues with
versions not launching.
I'm sure there's other situations where you can see the problem, but here is
what i've been making (you can see the same thing in my last tuto
https://www.youtube.com/watch?v=v8OekPfbri0)
STEPS TO REPRODUCE
1. Take an image or make a title clip with a big square, we'll call that Image
2. Add a color clip on v1, and Image on v2 and v3
3. Add Transform at 80% on Image on v3
4. Transform at 83% and Brightness at max on Image on v2
5. Add Composite and transform between all tracks
6. On the one between v1 and v2, change the last frame to 90%
OBSERVED RESULT
The image is shaky during the zooming out
EXPECTED RESULT
It should be smooth
ADDITIONAL INFORMATION
I attached videos on different versions of kdenlive, I tried to install older
Windows versions but for some reasons they wouldn't work, so I used the
appimages on my VM. And I tried the latest appimage but it wouldn't launch, so
my information is not very scientific since multiple parameters are changing,
but I tried my best.
SO it seems i can only add one video, so here's a drive :
