[QUOTE="frenzy, post: 374905, member: 73633"] Post a screenshot because as you see nobody understands "grainy" in the same way. We have a grainy=blurry and a grainy= interlaced-like. To me grainy=noisy but you could also mean blocky. Anyway with a VHS rip you won't get the same quality as with a DVD or even a TV transmission. VHS res. is 480x330 while DVDs as you probably know is 720x576. Another parameter is deinterlacing as was mentioned. Probably TVix is using some internal processing which you would have to simulate on your pc or is a really bad encoder (most probable).In any case try to use ffdshow and activate these filters in this order: [B]Resize[/B]: Specify Horizontal size: 1280 or 1920 (depending on your processor power [B]not [/B]your screen) [B]Resize Settings[/B]:[I]Lanczos, 4 taps and Luma sharpen .15, Luma blur .50[/I] [B]Noise[/B]: Luma noise 3, Chroma noise 3, mplayer noise, every other slider to far left (0) [B]Sharpen[/B]: [I]XSharpen[/I], [I]threshold 150[/I], [I]strength [/I]between 15 and 30.
