I am trying to caputre a camera during a show, and replay it afterwards. Or actually, I am trying to capture single images every 3 seconds and then replay it as a movie.

Isadora crashes randomly while capturing the images (sometimes earlier, sometimes later).
I replaced the idea of single images and tried capturing the camera as a movie. Isadora crashes in the moment I stop the recording.

The movie itself is playable afterwards. So I guess there is a conflict in adding it to the project, while others things are running. I tried capturing a little bit without anything else going on, and it didn't crash.

Any idea what else I can do or try to find the conflict and/or avoid it?

Thank you.
