You can create a new slider panel with the "coordset slider" command and specify the playback speed of the recorded movie file, for example,</div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>coordset slider #1 movieFramerate 5</div><div><br></div><div>The default frame rate for the recorded movie if none is specified is 25.

If you record with that setting slower speed it will play back at slower speed. That speed control says how many rendered graphics frames are show for each MD time. So if you set it to 10 then it will run 10 times slower than the default value where it is set to 1. When the movie is recorded with the record button it always sets the playback speed as 25 frames per second in the .mp4 file. But the same MD time is repeated for 10 frames so it runs slower. You may think that will produce a bigger movie file, but it does not, because of the H264 compression used for the movie.</div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>Tom</div><div><br><div><br><blockquote type="cite"><div>On Jan 12, 2023, at 12:10 PM, Visvaldas K. via ChimeraX-users <chimerax-users@cgl.ucsf.edu> wrote:</div><br class="Apple-interchange-newline"><div><div><div class="yahoo-style-wrap" style="font-family:Helvetica Neue, Helvetica, Arial, sans-serif;font-size:16px;"><div dir="ltr" data-setdir="false">Dear all,</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Is there a way to change frame rate when I hit that red "record" button when playing MD trajectory? <br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">I could do "movie record", <span><span>but then it becomes interactive</span></span> (I hit triangle "play", and then "<span>movie encode /Users/visvaldas/Desktop/movie.mp4 framerate 5"), so <span><span>inadvertently</span></span> can record some undesired frames.<br></span></div><div dir="ltr" data-setdir="false"><span><br></span></div><div dir="ltr" data-setdir="false"><span>Of course I probably can reduce framerate using external programs, but how to that non-interactively in ChimeraX?<br></span></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Best regards,</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Vis<br></div></div></div>_______________________________________________<br>ChimeraX-users mailing list<br>ChimeraX-users@cgl.ucsf.edu<br>Manage subscription:<br>https://www.rbvi.ucsf.edu/mailman/listinfo/chimerax-users<br></div></blockquote></div><br></div></div>_______________________________________________<br>ChimeraX-users mailing list<br>ChimeraX-users@cgl.ucsf.edu<br>Manage subscription:<br>https://www.rbvi.ucsf.edu/mailman/listinfo/chimerax-users<br></div></blockquote></div><br></div></body></html>
