Bug ID: 474802 Summary: All rotation effects cause black borders Classification: Applications Product: kdenlive Version: 23.08.1 Platform: Other OS: Other Status: REPORTED Severity: normal Priority: NOR Component: Effects & Transitions Assignee: j...@kdenlive.org Reporter: krzes...@gmail.com Target Milestone: --- SUMMARY *** If you, for example, accidentally record a video in portrait mode while holding the smartphone horizontally, Kdenlive won't be able to fix it: The "Rotate" and "Rotate and Shear" effects crop the video for some reason upon rotating, as well as leave it zoomed out with black borders. The Transform effect rotates it properly, but still leaves it zoomed out with black borders around, forcing you to zoom in by about 178% to make the video fit the project. I suspect this zooming could be lossy. There needs to be a proper way to rotate videos. *** STEPS TO REPRODUCE 1. Import a portrait video to the timeline (for example 720x1280) 2. Make sure your project has the right resolution (1280x720 in this case) 3. Try to use "Rotate", "Rotate and Shear" and "Transform" to rotate the video 90 degrees. OBSERVED RESULT "Rotate" and "Rotate and Shear" result in the video being cropped AND having black borders. "Transform" results in just black borders. EXPECTED RESULT No black borders, no cropped sides. SOFTWARE/OS VERSIONS Windows: 10 22H2 19045 ADDITIONAL INFORMATION Some of the Rotate and Shear tool's options seems to be redundant on top of the Rotate tool.
