However, 100 seems to equate to no compression, and the mpeg encoder does not understand the resulting video info. Hence, quality = 99).<br \/>\nConvert Quicktime file to MPEG-I:<br \/>\nExecute binary found in the mpegtools\/bin directory, i.e.:<\/p>\n<pre>mpeg2enc infile.mov -q 5 -o outfile.mpg<\/pre>\n<p>(the q 5 [= quality 5] setting seems to give the best appearance\/playback performance compromise)<br \/>\nmpegtools also allows the encoding of MPEG-II video files, so there&#8217;s no reason that we can&#8217;t output a 640 (or 720) width QuickTime file from personalStudio  and convert to MPEG-II.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>With the release of mpegtools by Marcus Lundblad, it is now possible to create an MPEG file from within BeOS, including video material edited in personalStudio. &#8222;mpegtools&#8220; is able to work with the Pegasus codec optionally used by personalStudio on analog export, so this should be the output codec used.
