I see the side move on the YouTube video. Do you have added these pictures direct to the timeline and you have not used the function “Add Image Sequence”. Correct? If you delete all clips except the first 4 ones -> does this shift still happens? If yes, can you upload the first 4 pictures so we can test. Watching the video again and it seems all pictures have this issue. After the transition the picture get slightly shifted to one side and before the next transition the picture gets slightly shifted to the other side. Can you upload a screenshot of you timeline and show me which transition settings do you use? Created attachment 154121 [details]

All pictures are added to Project Bin and then dragged to timeline. Basically: 1. Add pictures to timeline. 2. Overlap "old" and "New" versions of the same picture by 3 seconds and different pictures by 2 seconds. 3. Add standard "Wipe" effect by dragging purple dot. I have tried the Luma transition with same result. There are other "Then and Now" videos on my YouTube channel which show the shift. I haven't got the original timeline for this video, but I have recreated it with the first 4 pictures as you requested and the shift shows. The 4 files are attached (hopefully). I have attached a screen shot of the new test timeline. This is probably an issue in MLT's transition. I will try to investigate Created attachment 154142 [details]
Timeline_Same-Track-transition
Thank you for the pictures. Even with same-track-transition the slightly left/right shift is visible (even on the project monitor while playback).
I see this same issue on every transition on a Slackware64-15.0 Linux system using Kdenlive 21.12.1. Can someone please test this in the latest versions (24.12.3) to see whether this rather old bug still exists? Changing the severity doesn't help. I tested on Windows with the picture here available. Neither on 24.12.3 nor on master I can see the slightly left/right shift of the picture when a transition is attached. Setup same as attachment 154142 [details].
I close this bug. If it still appears in the latest version, please feel free to re-open it and update the affected version number.

bug using the wipe effect between two images
I still see the issue after re-rendering the project where I first noticed it.
I just upgraded to v24.12.3 (Flatpak) on a Slackware64 15.0 Linux system.
Here is the output from a test project where there's a "wipe" transition between two images: you can notice that the first image slightly tilts left as soon as the effect kicks in (around t=3s) and then tilts right as soon as it finishes (around t=5s).
I can attach the entire test project, if needed.
