Hi Christoph, Thanks for trying out the new Timeline panel. I received reports this issue but forgot to track and add for yesterday's patch; I'll make sure that the PNG frame export is consistent with the timeline for the next patch release.
As for the 30 global frames vs 60 composition frames you see, this is another difference from PyMOL2's movie maker, which perhaps could be made a little bit more clear in the documentation. In the previous movie maker version, the number of frames exported from a movie was intimately tied to molecular state whereas in PyMOL 3, each composition's length is set independent of multistate objects. The composition FPS is currently locked at 60fps for now, but this will eventually be customizable per composition soon. Best, Jarrett J.
