<p>3 revisions</p> <p><b>New page</b></p><div>== Codecs ==<br /> <br /> I've made movies with the DivX codec and those, in my experience, make the best movies. They take a while to encode, and are large, but have the best output quality.<br /> <br /> ===Mplayer/Mencoder===<br /> I used '''mencoder''' to make a movie. The best encoding command line was,<br /> &lt;pre&gt;<br /> mencoder -mc 0 -noskip -skiplimit 0 -ovc lavc -lavcopts \<br /> codec=mpeg4:vhq:trell:mbd=2:vmax_b_frames=1:v4mv:vb_strategy=0:vlelim=0:vcelim=0:cmp=6:subcmp=6:precmp=6:predia=3:dia=3:vme=4:vqscale=1 \<br /> mf://*.png -mf type=png:fps=18 -o output.avi<br /> &lt;/pre&gt;<br /> <br /> This gave me an 18 frame-per-second divx/mpeg4 movie with superb quality. The movie is large and is at [http://vertrees.org/~tree/movie Arrestin Vs Rhodopsin (DivX)]. The input are all the files ending in &quot;.png&quot; in the current directory; the output is output.avi, the movie. The three lines are actually on long one; concatenate them at the black slashes '''\'''.<br /> <br /> === Quicktime ===<br /> Recent attention to transparencies and QuickTime show that one typically wants to set<br /> set ray_opaque_background, off<br /> to tell PyMol to stop using Alpha-channel for transparencies and switch to blending.<br /> <br /> If you're having transparency problems this could be a fix.<br /> <br /> [[Category:Third_Party_Software|Software CODECS]]<br /> [[Category:Movies]]</div>
