Chroma keys clitches when rendering

Hi,

I am trying to create a title video for one of my project. When I am rendering the video, I can see a brief appearance of the green background every now and then in the footage. And when I play the completed video, I get this annoying flickering effect from the green showing through at random moments - and it's happening a lot within the clip. In other words, there are many instances where only the green screen track is visible (no background track) during the rendering and the finished video - if that makes any sense. And like I mentioned, these issues are not visible when the project is played in the preview.

I tried to redo everything from scratch, but the problem does persist.

Thanks for your help.

Here what it looks like.

Two possibilities.

-- Your green screen is not quite keyed properly, or

-- You need to turn off GPU rendering for this project.

This usually takes care of most problems.
