KVCD: Confused with overscan settings
GripFit( width=352, height=480, overscan=0)
The film is full screen, but I also need information on 16:9. How do I set overscan for: 16:9 ntsc film ? 4:3 ? This is an avs I'm testing with SKVCD: LoadPlugin("d:\videoutil\MPEG2DEC.dll") LoadPlugin("d:\videoutil\LegalClip.dll") LoadPlugin("d:\videoutil\Sampler.dll") LoadPlugin("d:\videoutil\DustV5.dll") #LoadPlugin("d:\videoutil\TemporalCleanerOld.dll") LoadPlugin("d:\videoutil\GripFit_Preview.dll") LoadPlugin("d:\videoutil\Convolution3d.dll") LoadPlugin("D:\Videoutil\Decomblegacy.dll") mpeg2source("D:\snow_white\snowwhite.d2v") telecide() decimate() LegalClip() GripCrop(352,480, overscan=0) GripSize() FaeryDust() #SpaceDust() Convolution3D(preset="movieHQ") GripBorders() LegalClip() ConvertTorgb24 (I have ATI drivers and must use) trim(Round((Framecount/2)-((Framecount/10)/2)),Round((Framecount/2)+((Framecount/10)/2))) Sampler(length=24) |
if you increase the overscan, you are making the picture more central on a tv screen (I think, correct me if I'm wrong). so you don't miss any of the action going on in a movie.

@ Kwag & andybno1
thank you friends, now is clear! :D and overscan seems fantastic! :wink: copy from Kwag's post: "Consumer TV sets use overscan to prevent black vertical bands from appearing due to variations in the horizontal deflection circuitry of TV sets. Overscan causes a loss of an average of five percent of the image on each side of the tube. So when you set overscan blocks to 1 or 2, you're encoding less film area and making the image smaller. When you play it back on your TV, it will be expanded flush with the edges and you won't loose image on the sides Overscan 0 doesn't do any resize. 1 = 8 lines on each side, and 2 = 16 lines on each side. -kwag" :wink: |
