Movie Data Conversion Test 2

Last Change: 29/Oct/2010

Time to convert 11.4 seconds of half-size-PAL MJPEG-A to quarter-size MJPEG-A with mediaconvert (minutes and seconds).

As of 05/Aug/09 I am using the command line dmconvert to run this test, to attain better accuracy. Over time I'll rerun the test on all systems in the same way. Old data are those without the sub-second timings. The conversion command used is:

  timex dmconvert -vf qt -p audio -p video,rate=25,size=184x144,comp=qt_mjpega,il=odd,squal=0.95,tqual=0.75

Note that if a result seems oddly out of order (eg. R5K/200 O2), it's usually because the OS version is different, ie. changes made to dmconvert/mediaconvert can affect performance. Disk speed may also be relevant, though whenever possible I run the test using a Seagate ST336704LCV 36GB 10K. Eventually I'll rerun all the tests to use the same type of disk.
