Hi Maria, Ok, so the bug is not fixed in Chimera version 1.2304. I made a note of that in our bug database. Here is a suggestion from the original bug report that solved the problem in that case: Edit the file in you Chimera 1.2304 distribution chimera/share/MovieRecorder/RecorderHandler.py using any text editor to change line 97 from image = chimera.viewer.pilImages() to width, height = chimera.viewer.windowSize image = chimera.viewer.pilImages(width, height, supersample = 1, opacity = False) Make sure to use the same indentation as the original code since this is important in the Python language. Then restart Chimera and try movie recorder again. Let me know if that fixes the problem. Tom
