Bug ID: 403944 Summary: Stabilizing 30fps clips in 60fps project problems Product: kdenlive Version: 18.12.1 Platform: MS Windows OS: MS Windows Status: REPORTED Severity: normal Priority: NOR Component: Effects & Transitions Assignee: vpi...@kde.org Reporter: czart.and...@gmail.com Target Milestone: --- SUMMARY In some specific cases stabilization does not produce good results if a 30fps videoclip is stabilized in a 60fps project. The problem occurs when something on the video moves from the opposite directions (for example when you're moving form left to right, and a car moves from right to left). (Link to an example is attached.) STEPS TO REPRODUCE 1. Create a 60fps project. 2. Import a 30fps video to the project bin. 3. Stabilize the video, then add it to the timeline, then render the project. OBSERVED RESULT The moving objects are strange on the stabililized video when something on the video moves from the opposite directions (for example when you're moving form left to right, and a car moves from right to left). (Link to an example is attached.) EXPECTED RESULT If the 30fps video is stabilized in a 30fps project, the result is a well stabilized video. SOFTWARE/OS VERSIONS Windows: MacOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION Well, you might ask why would I stabilize a 30fps video in a 60fps project. I shoot lots of videos with an actioncamera, and when I have light I use 60fps, but at night I use 30 fps. When I edit the videos, the final video will be a 60fps video, so I use both 30fps and 60fps videos in my project. One possible solution would be to stabilize, and render the 30fps videos in a 30fps project one by one, but as I shoot lots of short clips, that would take lots of time. (My workaround is that I use a script in a linux virtual machine to stabilize my videos automatically one after an another using ffmpeg, which doesn't change the framerate. Then I add the stabilized videos to kdenlive.) Here is a videoclip for demonstration: (the tuktuk and the second taxi looks really strange) https://drive.google.com/open?id=1Ro5ZC93Fg9xrcN60poHketisCzFm6Cg1 -- You are receiving this mail because: You are watching all bug changes.
