SUMMARY Firstly masking a section of a clip appears to be a challenge without producing it this way. In order to blur a logo, a copy of a clip on one track was copied to a second higher track. A Box Blur was applied along with an Alpha Mask. The preview window displays the correct output, however when rendering the video it is as if the track is not there. STEPS TO REPRODUCE 1. Load a clip to V1 2. Copy the same clip to V2 3. Apply a box blur and rectangular alpha mask to clip on V2 and observe in preview 4. Render the video (Using WebM codec) and observe blur is not present OBSERVED RESULT See points 3 and 4 above. Blur on track present in preview, but is not present in the final render EXPECTED RESULT Blur on track should be present on both preview and final render. Hope you can shed some light on this matter SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
