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.)
Hi, thanks for your report, movit is still very experimental, so expect weird behavior...
Hi! Please note that MOVIT has been experimental so far and was not well maintained. Due to lots of issue we recently disabled it. See https://invent.kde.org/multimedia/kdenlive/-/commit/41b74bd282e8a96be3b75f423f8101fa506d858d In the long run there are plans to add a GPU again either with enhanced MOVIT or a new system, there is no eta yet. Thanks again for your report!
