In general, the Intel graphics (OpenGL) drivers are buggy and you
would be better off using a computer with NVIDIA or AMD/ATI
graphics. However, the recent (less than a year old or so) Intel
drivers are considerably less buggy than the previous ones, so the
problem might be fixed by updating your graphics driver (as long as
you don't have Intel GMA 500 graphics, which you don't). This is
the recommended solution because it can fix a whole slew of graphics
bugs.<br>
<br>
If updating the graphics driver doesn't work, a workaround would be
to turn on 1x1 supersampling in the Movie Recorder tool (in Frame
Options) -- that uses the Save Image code path, but slows down
recording images. If you are recording movies using a command
script, that is not a problem, it just takes longer. But if you are
recording movies interactively, it is.<br>
<br>
If you still have problems after trying the above solutions, please
submit a bug using chimera's Help / Report a Bug dialog.<br>

<p class="MsoNormal">My movie seems to render, and the movie
file is created, but when I open the file and play it, it’s
just a blank (all black) video. When I examined the captured
frames, they’re also all blank black frames. If I choose “Save
image”, it saves it just fine, so I guess the image capturing
algorithm for movies is different the one for saving the
images.<o:p></o:p></p>
