What is your operating system?
What is your Shotcut version (see Help > About Shotcut)?
Can you repeat the problem? If so, what are the steps?
Chroma key, used for green screen, work only for 2 seconds, then the mask disappear and show the green…
I’ve used the filter some years ago. Now it works bad on same video
Can you check?
SC v23.06.14 can you try on
I’ve tried. Same bad results…
At the beginning it’s a chroma key, then it’s full green…
I thought maybe it was due to the version… More advanced users will help.
Not a bug. You do not have anything to blend with after 2 seconds. Before the two seconds there was a video. What do you want to see in the transparent areas after 2 seconds? You need to put that in on a lower track.
The reason why Chroma key seems to stops working after 2 seconds is because the timeline under your greenscreen clip becomes empty.
I thought a black background, but it’s my fault. Now it is working
