Hi
Is there a trick to rendering chroma key into a video? In Kdenlive I am able to play the chroma keyed animated video inside kdenlive but when I render it it just shows a blank white screen over top of my video.

I changed the format to WebM(from MP4) and improved the quality and now it rendered it correctly. Not sure which of the two made the difference though

can you provide more informations? do you have a small video to reproduce the issue ?
