4.12.5 sequencer stucks

Hi all
I’ve created a medium complex scene.
I did set up 5 cameras and created 5 cuts + dissolve
When I try to save the jpg sequence Unreal stucks and does nothing, cursor disappears, I can’t stop the render, I have to kill the app.

regards

Do you see your animation? If not, it’s possible the sequence isn’t playing and therefore doesn’t know when to stop. Do you have autoplay on for the level sequence actor that corresponds to your sequence? Or are you playing the sequence through blueprint?
