</a><br><br><br><br><br><br>It's not nuvexport that does the actual exporting. Nuvexport just runs<br>ffmpeg, transcode, or mencoder (whichever you choose). Also, since you can<br>change the quality settings to your liking, exporting times can vary with
<br>all 3 programs. To give you an example, I use transcode, export to xvid with<br>quality 8 setting, and I am able to export a 1 hour recording (42-45 minutes<br>total when there are no commercials) in about 35 minutes. I have a core 2
<br>duo running at 2.4ghz. Transcode will utilize both cores, mencoder will not<br>(can't remember about ffmpeg).<br><br>If I was to export to dvd (instead of xvid), it would probably be way faster<br>(10-15 minutes or so) because there is not much compressing going on. Also,
<br>I don't use multipass, if I did, it would take twice as long to export each<br>recording.<br><br>-Hope that helps<br>-Steve<br><br><br>_______________________________________________<br>mythtv-users mailing list<br>

I wonder, which one gives better results? Transcode, ffmpeg or mencoder?<br>I am assuming the same size file as an end result.<br clear="all"><br>-- <br>------------------------------<br> /\_/\ <br> |O O| <a href="mailto:pepebuho@pananet.com">
