SUMMARY Effect Oldfilm not working here. I’m using Xubuntu 22.04.2 LTS and kdenlive 23.04.2. I can add the effect to the video clip but nothing changes. STEPS TO REPRODUCE 1. Open Kdenlive 2. Add a video clip to timeline 3. Add Oldfilm effect to the video 4. Preview the timeline, without changes to the clip OBSERVED RESULT No changes to the clip EXPECTED RESULT Effect appyed to the clip SOFTWARE/OS VERSIONS Linux: Xubuntu 22.04.2 LTS Kdenlive: 23.04.2 ADDITIONAL INFORMATION I'm using the ppa install. Tried to reinstall kdenlive, kdenlive-data and melt and the problem persists, even when removed config files. When I remove the ppa version and install the version in Xubuntu repository (old version) the effect works.

Running the oldfilm filter from the command line (melt <video.mp4> -filter oldfilm) works OK Running other MLT filters from within kdenlive (e.g. greyscale) works OK
I can confirm this for 23.04.2 under Linux (appimage and ppa install) also for the dust effect. Both oldfilm and dust work in 22.12.2
Thanks for the report and input. This bug seems to be happening inside MLT. These effects don't work when applied to an MLT chain, but work on MLT producers (MLT recently introduced chain containers for video clips). I will investigate and give feedback asap.
I just opened an MLT issue to track the problem: https://github.com/mltframework/mlt/issues/927
