Movie Playback Performance

Due to my wife's illness and a desire to get the review published quickly, I used a simple but stressful test to determine movie playback performance - a 320x240 Cinepak QuickTime movie stretched to full screen in 1024x768, thousands color mode. The movie was loaded into RAM to prevent the CDROM drive's performance from affecting the scores.

Be aware that Quicktime will not use the hardware scaling/acceleration features of your card if you scale the movie up an exact 2X factor. For exact 2X movie size playback, software scaling only will be used. Also note that some cards (i.e. ATI) only accelerate Quicktime movies that use the CinePak and Indeo codecs. In the past these two codecs have been the most popular, but with Quicktime 3.0 now released other codecs like Sorensen may become more popular due to their compact file sizes. Since Quicktime 3.0 is fairly new, I still use version 2.5. This allows comparisons to previous results as well since those tests were run with that version.

The results of the frames played and max framerate tests in MacBench 4.0 using the above parameters are shown below:

MacBench tests: 320x240 movie stretched to 1024x768 (full screen) MB max frame rate tests

As shown above, the ProRez performed well, and image quality seemed good. I rated movie playback based on this admittedly limited test a 9.

The next page has details on the software controls and hardware features.
