Questions on recording movies for use in PowerPoint
Hi We have just installed Chimera on a MacPro running OS X 10.4. I would like to be able to record simple movies of rotating peptides for use in PowerPoint ( 2003) presentations. I have been able to record and insert the avi format into PowerPoint and the movie does play correctly. But I am noticing a considerable loss in resolution as compared to the original molecule in Chimera. Is there some adjustment I should be making in Movie Recorder to improve the image resolution? Should I be running POV-Ray on these files? Thanks for any suggestions. Gene (Eugene Coats)
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.

Hi Tom, Thanks for the suggestions. The changes in settings you suggested improved things considerably.
