Hello Everybody,
I've got an issue when trying to playback a high-quality 1080i MPEG-2 content using QuickTime on my dual-GPU Macbook Pro.
OK, this format has become playable after installation of QuickTime MPEG-2 playback component, but deinterlacing quality is not even close to a one found in Boot Camp (I run Snow Leopard and Windows 7 via Boot Camp). Since this is the same hardware deinterlacer of Geforce 9600M GT GPU, I'm wondering why the quality is so poor in Snow Leopard... Basically, not all artefacts of interlacing are removed, that resuls in quite an ugly output... My investigation shows that in Windows 7 a perfect quality of HW deinterlacer is not available when Balanced or Power Saver power management profile is used. It's available only if High Performance power profile is selected, thus GPU is allowed to work at 500/1600 MHz (Core/RAM). However, by selecting High Performance in Snow Leopard's Energy Saver Preference Pane, no there no improvement of deinterlacing quality.
As a sample clip, I would recommend this one (in fact, very beautiful one - filmed using one of the world's finest digital cameras): http://uploading.com/files/fdad32a9/Spain3_orig.mpg
A lot of odd lines (traces of interlacing) are clearly visible in this clip, e.g. when a girl walks (at the beginning of this clip).
Just any kind of advice is highly appreciated.
