https://bugs.kde.org/show_bug.cgi?id=501245 --- Comment #11 from [email protected] --- “Average blur” must be placed ABOVE the “Transform effect.” This information was missing. That's a temporary solution. -- You are receiving this mail because: You are watching all bug changes.

The issue you are seeing is because I made some changes to the Transform effect to fix shakiness when doing slow zooms. Zooming was not smooth because the rescaling was done with a pixel precison level, so sometimes you could see some "hicups" in the zoom. Original bug is here: https://bugs.kde.org/show_bug.cgi?id=497435 The scaling is now done at a sub pixel precision, which means that if you have an image with a resolution higher than displayed, on small moves you can see some pattern changes. The workaround is to apply a very light blur effect to your image to reduce the patterns, which should give you the expected result. Try for example to add an "average blur" with the default parameters (x=1, y=0) and you should have smooth zooming with no noise. -- You are receiving this mail because: You are watching all bug changes.

As soon as the “transform effect” is active in the current version (24.12.2), the image starts to “glitter”.

The zoom with the Transform effect is smooth and only with very little banding. But the zoom with the PaZ effect is quite ugly with lots of banding and jerkiness in the movement. I tried with 30fps and 60fps and the results are the same. BTW, in your video, there is some banding in the PaZ version (see the knee pads of the front man). But it is a lot less than the Transform version. Still, I am wondering why my PaZ version is so much worse than yours ... -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=501245 [email protected] changed: What|Removed |Added Status|NEEDSINFO |REPORTED Resolution|WAITINGFORINFO |--- --- Comment #4 from [email protected] --- I had to compress the video a lot to get it below 4,000 KB (render quality “35”). The “Position & Zoom” then doesn't look quite so bad. However, both effects have their own problems. At least everything looks disastrous in the preview. I can't explain the reverse behavior between the two effects in your case. The reported error is very specific 🤷♂️. I had wondered why the complete video suddenly came to 280 MB after the update to 24.12.2 (instead of 160 MB as before). Until I realized that it was specifically due to this image. When rendering, the file size suddenly shot up in certain places and then it continued slowly (with the “Ministry” image). -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=501245 --- Comment #5 from Bernd --- A few more tests: * Original video (as linked here) is 3.8MB * My first render (using the Generic profile MP4-H264/AAC) with default project settings (using Full HD profile HD 1080p 60fps) is 47.3MB * Transform has banding but is otherwise good, PaZ is horrible * Next test with the same project and render profile but selecting Lanczos for interpolation * File size is 37.9MB * Transform still has some bending, PaZ looks really good (except for some strange noise at the left edge) * Another test with Lanczos and a Vignette effect drops the file size to 27.7MB (go figure) The image file with all t.he dots doesn't lend itself well for zooms or other transformations but with the right interpolation good results can be achieved. The noise on the left edge can be obscured by using a vignette effect (need to adjust the parameters a bit, though). -- You are receiving this mail because: You are watching all bug changes.
