Whyagaintango: /* Exporting your Movie */ cleaned up save movie as mpeg

== 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→Save Movie As→MPEG
*File→Save Movie As→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''').
<source lang="bash">
setenv /my/long/path/to/freemol-trunk/freemol
cd freemol-trunk/src/mpeg_encode
</source>
(Ignore all other directories inside directory '''src'''. These were unnecessary, at least for me. No need make install).
<source lang="bash">
./configure
make
</source>
Add these two lines
<source lang="bash">
FREEMOL=/my/long/path/to/freemol-trunk/freemol
export FREEMOL
</source>
to your pymol script. 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.
