Bug ID: 427458 Summary: rotoscoping issue with Movit library Product: kdenlive Version: 20.08.1 Platform: Ubuntu Packages OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: Effects & Transitions Assignee: vpi...@kde.org Reporter: d2r...@126.com Target Milestone: --- SUMMARY rotoscoping issue with Movit library STEPS TO REPRODUCE 1. Setting - Configure Kdenlive - Playback - enable GPU processing 2. after reboot, use rotoscoping to map. 3. does not work.(likely due to movit.overlay) OBSERVED RESULT rotoscoping does not work. However, other GPU feature working as normal. EXPECTED RESULT rotoscoping creates a "masking" effect, so parts of the visual in the layer under appears in the preview, and the final video. SOFTWARE/OS VERSIONS Windows: N/A macOS: N/A Linux/KDE Plasma: Linuxfx(5.6.15-windowsfx-10-generic) based on Ubuntu Focal(20.04LTS) (available in About System) Kdelive Version: 20.08.1 via Ubuntu PPA KDE Plasma Version: 5:104ubuntu4 KDE Frameworks Version: 5.68 Qt Version: 5.12.8 ADDITIONAL INFORMATION This issue is likely due to the movit.overlay function as converting the project back to CPU only fixes the problem. However, this workaround often comes with huge performance drawbacks. SUGGESTION 1. adding a "rotoscoping(GPU)" function and make "Rotoscoping" a CPU-only function. 2. try fixing movit.overlay implemntation?(I am not a good coder, so please forgive me.) -- You are receiving this mail because: You are watching all bug changes.
