<DIV dir=ltr><FONT face=Arial size=2>In the PC based powerpoint, the codec for mpeg is not the same code for windows!</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>they seemed to diverge many years ago and the PPT decoder is pretty limited; </FONT></DIV>

<P><FONT size=2>Hi Markus,<BR><BR> First I'd suggest that the best supported movie format on the Mac is<BR>Quicktime, so you should use the Chimera movie command option "mformat<BR>mov", or leave the mformat option out since quicktime is the default.<BR><BR> As Damir mentioned sometimes movies play on one screen but not a<BR>second one when two displays are used at the same time. I haven't seen<BR>that on a Mac but have on Linux. I would not expect this to be<BR>dependent on the movie format, but it is possible that some formats<BR>allow simultaneous display at two screen resolutions while others don't.<BR> It would be worth testing some other movie not made in Chimera in<BR>powerpoint in the same presentation to see if it is a specific problem<BR>to the Chimera movie.<BR><BR> To get higher resolution you want to record the movie with a larger<BR>Chimera window. If you are going to play the movie full screen in a<BR>presentation than you need to record it with a large Chimera window so<BR>it does not have to be blown up too much which would make it blocky.<BR>The Chimera supersample option is just a way to smooth the appearance --<BR>it doesn't increase the resolution. The movie encoding bit rate also<BR>does not increase the resolution -- it simply reduces the artifacts<BR>introduced by compression such as halos around objects.<BR><BR> Tom<BR>_______________________________________________<BR>Chimera-users mailing list<BR>Chimera-users@cgl.ucsf.edu<BR><A href="http://www.cgl.ucsf.edu/mailman/listinfo/chimera-users">http://www.cgl.ucsf.edu/mailman/listinfo/chimera-users</A><BR></FONT></P></DIV></BODY></HTML>
