Bernd <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|REPORTED |RESOLVED CC| |[email protected] Resolution|--- |REMIND --- Comment #2 from Bernd <[email protected]> --- The filter boxblur is currently set to accept a max value of 540 for the luma_radius parameter. I guess this is due to 1920x1080 being the most commonly used (default) dimensions for projects. According to the ffmpeg (avfilter) documentation, the value for luma_radius must be >= 0 and <= min(width, height)/2, meaning that of the two values for width and height the smaller one is divided by 2 for the max value. For 1920x1080 that would be 540. Unfortunately, there is no way to express that limit in the XML file used to define the effect/filter. So, if you are using this effect on a project with less than 1080 pixels wide, simply keep the slider below 50% of the width. Closing this a RESOLVED - REMIND to see if MR 794 (https://invent.kde.org/multimedia/kdenlive/-/merge_requests/794) may allow this in the future. -- You are receiving this mail because: You are watching all bug changes.
