I've been trying to create a smooth Ken Burns effect with Pan and Zoom. Sometimes it works fine. Other times, especially with small objects like tree branches, it flickers very badly and is uncomfortable to watch. It's been suggested that I add some blurring effect to ease the problem. This only works to a limited extent, with the end result being that the flickering is now blurry too. Is there another way of creating Ken Burns in Kdenlive? I've tried using composite transitions and it's not much better.
