Hi Gene, Use the Movie Recorder dialog Movie Options pane and increase the "bit rate" from the default 2000 Kbits/s to say 6000 Kbits/s. If you are using the "movie" command use the option "bitrate 6000". Another option that will improve the quality is to turn on supersampling (3x3) in the Movie Recorder Frame Options panel, or use "supersample 3" with the movie command. This will create an image 3 times larger for each frame and then smooth it down to the size of the Chimera window. That eliminates jagged edges. More details are in the Chimera manual. http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/recorder/recorder.h... http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/movie.html Raytracing will give a glossy appearance with better lighting highlights and with shadows but the appearance can be somewhat different then what you see on screen.
