I am editing a video with footage from three cameras. Two are 25fps and the third one is 50fps, so I set the project fps to 25 and I have a Speed control effect strip on the 50fps footage, set to Multiply 2. The video strip and the Speed control speed are in a meta.

As the footage is long, the camera split it into multiple file. So I have three movie+speed metas one after the other. I put these all in a meta, to have a single video strip to work on for that camera.

When I select the meta-meta and hit K to cut (trimming the beginning of it), Blender crashes.
