Created attachment 150145 [details] This archive contains .pdf report and 3 images SUMMARY The report title already says, what is the problem. But TLDR - Kdenlive's effect "Transform" (and composition), when scaling down the picture, does not take in consideration all the pixels. It takes in consideration only the "closest pixel/s". This leads to crippled image quality, because majority of pixels are ignored. This should not happen and has been in Kdenlive for a very very long time. In attachment I have added a .pdf report and the image files, which were used in the test. I made a .pdf report, because in order to describe the problem in detail, you have to read and look at the comparison pictures. STEPS TO REPRODUCE 1. Read the .pdf report pls 2. Read the .pdf report pls 3. Read the .pdf report pls OBSERVED RESULT Image with destroyed quality EXPECTED RESULT Image without destroyed quality SOFTWARE/OS VERSIONS Ubuntu 22.04
Good news. The issue has been fixed in kdenlive-22.08.2 . I tested and the issue still exists in kdenlive-22.08.1. So, it means the issue was solved in the last version.
