This issue is known. The speed effect is still not stable even in the latest version 18.08.3 (use the AppImage). Maybe it’s a bit better. In the upcoming refactoring release the speed effect is completely new written. Use the speed effect with care.
Thank you for fast answer. Thank you for information that "speed" is the problem. I will render a extra clip, e.g. myclip-speed150percent.mp4 and will re-integrate it to the project. I can live with that bug. Thank you to all KDE programmers, developers, .. It's a wonderful software! Drawing strokes with head in "Add title clip" would be helpful, and inserting pics by drag&drop. The rest is nearly perfect! I'll make a donation again!
Thank you for the feedback. I don’t understand really what you mean by “Drawing strokes with head". Yes, drag/drop picture into the title clip would be nice. Please open a new “Bug” for these 2 items and declare the Importance as wishlist.
"arrows" - I meant that! = strokes + head :)) sorry, my bad english . OK I make a report and markt it as wishlist. Thank you so much!
The speed effect is solved with version 19.04.0. We close this bug. If it still appears in the latest version, please feel free to re-open it and update the affected version number.
