Hello, I have a strange problem with slow motion. I record 1080p 60fps video and I often do 0,5x speed of and export movie in 1080p and 30fps. One year ago there wasn’t any problems, slow motion was perfect, but 2 months ago I’ve started to see a lot of lags.
60fps + 0,5x speed = 30fps slow motion.
I have 19.01.27 version. You can clearly see this problem for example in this car test from my Youtube channel (scroll to 0:31). Every movie from my channel I made in Shotcut with Samsung Galaxy S7.
Funny thing: In Shotcut 16.11.02 everything works fine.
Sorry for my English if you found any mistakes.
