== Exporting your Movie ==
This wiki already has lots of information on how to convert your PyMOL movie to another format.  Check out [[Making_Movies|those]] [[Software_Codecs|pages]].

Once you've setup your movie as in any of the previous examples, you have a couple options for making a movie.

'''Export from PyMOL''': Newer PyMOLs support 
*File&rarr;Save Movie As&rarr;MPEG
*File&rarr;Save Movie As&rarr;PNG Images
from the menu.

'''mpeg''': This needs a bit of work. The following instructions work with trunk (1.2r2pre). Compile pymol trunk. 

Checkout [http://freemol.org freemol] source from 
<source lang="bash">
svn co svn://bioinformatics.org/svnroot/freemol/trunk freemol-trunk
</source>
This creates a directory called '''freemol-trunk'''. 
Inside '''freemol-trunk''' is a directory called '''freemol'''.
Now you need to setenv (or export) a variable called FREEMOL pointing to the above folder - '''freemol''').
In TCSH and related C-shells:
<source lang="text">
setenv FREEMOL /my/long/path/to/freemol-trunk/freemol
cd freemol-trunk/src/mpeg_encode
</source>
or in bash:
<source lang="bash">
export FREEMOL=/my/long/path/to/freemol-trunk/freemol
cd freemol-trunk/src/mpeg_encode
</source>

And then 
<source lang="bash">
cd freemol-trunk/src/mpeg_encode
</source>
(Ignore all other directories inside directory '''src'''. These were unnecessary, at least for me.)
<source lang="bash">
./configure
make
make install
</source>
Add these two lines
<source lang="bash">
FREEMOL=/my/long/path/to/freemol-trunk/freemol
export FREEMOL
</source>
to your pymol script (''i.e.'' /sw/bin/pymol). Launch pymol and '''Save Movie as MPEG''' should work now. No need of any complicated codecs.

'''mpng''': You can still use the good old [[mpng]] option to save all your frames to disk.  You can then compile them into a MPEG (see below).

'''Old Style''': One of the older scripting styles was to make minor changes and dump PNGs.  This is essentially obviated with PyMOL's new movie-making functionality.  The '''old style''' was to simply call cmd.png every time you made a scene change.

Hints:
* Movie not ray traced?  Make sure you set ray_trace_frames to 1.

=== Codecs ===
See [[Software_Codecs]] for information on how to stitch together movies from PNGs and optimize them for great crisp-looking movies.
