Hi!I have a quesion to LCD TV owners. Most of the new LCD TVs have a "motion compensation" feature. Is it deinterlacing the picture? I'm going to buy Sony40", to connect to PC via DVI/HDMI with 720p or 1080p and run VDR with vdr-xine. Now Im using nvidia xxmc and the deinterlace is ugly. With LCD TV it'll be visible much more, so I need better deinterlacing - so I'm wondering if TV hw motion compensation will do it...
TVs de-interlace would matter with interlaced output but I suppose field/frame accurate scaled and original way interlaced e.g. 1080i output is not possible with Nvidia and X.org. I'm using progressive 1080p50 output for 576i50 DVB-T/S video. Libxine handles de-interlacing, and Xv driver in Xorg the scaling with graphics hardware. The magic spell from xinelibout config is
xineliboutput.Video.DeinterlaceOptions = method=Greedy,cheap_mode=0,pulldown=none,framerate_mode=full,judder_correction=0, use_progressive_frame_flag=1,chroma_filter=1,enabled=1
The result is IMHO pretty good with a 50 Hz X.org mode where syncronization to vertical refresh is usually close to perfect. De-interlacing consumes more CPU than 576i MPEG-2 video decoding.
Advertised techniques for frame rate interpolation to 100/120 Hz perhaps matter more for typical Blu-Ray low rate 24p videos than 50/60p progressive video from PC. I haven't seen those in action so I'm only guessing.
