Created attachment 175643 [details] Ramping saturation before setting effect zone SUMMARY Setting an effect zone to an effect that has keyframes creates inconsistencies in rendering and maybe in the saved project file. STEPS TO REPRODUCE 1. Put a (eg. red) color clip in a new sequence. 2. Add a saturation effect to it ; set several keyframes to ramp saturation level from 1 to max. 3. Add a zone to the effect which starts at roughly the middle of the clip. 4. Run the clip in the preview monitor. OBSERVED RESULT Before entering the effect zone, the color is not affected by the saturation effect. Upon entering the zone, saturation drops to 1 then ramps up. EXPECTED RESULT Before entering the effect zone, the color is not affected by the saturation effect. Upon entering the zone, saturation drops to whatever value the interpolation between keyframes gives at this point, which, if the effect zone starts at the middle, is not at all 1. SOFTWARE/OS VERSIONS Operating System: Kubuntu 24.04 KDE Plasma Version: 5.27.11 KDE Frameworks Version: 5.115.0 Qt Version: 5.15.13 Kernel Version: 6.8.0-48-generic (64-bit) Graphics Platform: offscreen Processors: 8 × Intel® Xeon® CPU E3-1245 v5 @ 3.50GHz Memory: 31.2 Gio of RAM Graphics Processor: NVIDIA GeForce GTX 1650/PCIe/SSE2 ADDITIONAL INFORMATION Tested with appimage 24.11.70. It seems saving the project after the effect zone was set also does strange things to the file. See attachments.
