Re: Help! Svp - Sony bravia - motionflow
but it decreases smoothness from 60 to 48 (which is massive)
This is debatable - when I last tested it, 24fps --to-> 48Hz was smoother but 24fps --to-> 60Hz felt "faster".
However, 25fps really doesn't go into 60Hz mathematically well at all (2.4x? eww) , so I still very much recommend using 50Hz for that.
Nevertheless, one key factor is that doing 2x interpolation is less CPU-heavy than doing 2.5x interpolation, so you will also have more headroom to increase the SVP settings and thereby making up the difference with regards to that above-mentioned "faster feeling" that you'd find with 60Hz.
The TV and video card I'll leave it at 60hz
MPC-HC has an automatic resolution / refresh rate changer that can be set to automatically use a specific refresh rate (such as 50Hz) for a specified frame rate range (such as 24.5fps to 27fps). For example, I use the following settings (though you'd probably want to use 1080p rather than 720p unless 99.99% of the videos you watch are 720p at max)
