problem with rendering level sequence to video

I’m using the level sequence to create a video, and I came across an issue while rendering the sequence to video.

I have created the CineCameraActor track and the Camera Cuts track (see sshot), and the rendering works ok except for one detail… If I move the mouse while rendering, the camera rotates and this rotation ends up in the rendered video. Also, when the render starts, the camera doesn’t have the same angle as the start angle in the level sequence.

How can I fix this?

P.S. The checkboxes “Allow movement” and “Allow turning” in the “Render Movie Settings” are unchecked (see sshot), which suggests that moving the mouse shouldn’t move rotate the camera while rendering. Could this be a bug?

Yeah, I believe it’s a bug. There’s a similar issue we fixed for the upcoming 4.18 release. I just tested it there and I’m not able to move the camera with those checkboxes unchecked (correct behavior).
