Description Marlon Rebello Viana 2020-09-29 02:57:36 UTC

SUMMARY
In preview mode all is fine, but when I use any rendering mode, kdenlive just bug all transitions and effects in exported video, sometimes transitions are delayed or overlap. I can't render because this




STEPS TO REPRODUCE
1. put many images in "chain" during miliseconds in timeline with some effects(just someting fast)
2. render in any mode.

OBSERVED RESULT
The images will not in same order put in preview in render and some effects will not work correctly (just opacity or fade in / fade out effect)

EXPECTED RESULT
- Effects Work
- Transitions work
- order of images not be altered 
This works in render not just in preview

It could be that you use a couple of effects. Please disable parallel processing before you render. Then click on more options and pull the encoder speed slider to the far right with threads 0 to have a quick rendering.

Please confirm if parallel processing was the issue
