Overscan (what does that means ?)

[cd090580]

Hi,
I always rip my dvd's / tv captures to svcd and I never used Overscan.
Now, I've downloaded FitCD to calculate the bitrate and to test the capabilities. I noticed that FitCd uses 8 pixels Overscan all around the picture.

What's the utility of Overscan ??

When I resize a 4:3 dvd (full screen) to svcd I neveradd overscan (is it better to add it or simply do a direct resize).

When I resier I do it like this in avisynth (my DVD is in PAL format):

LanczosResize(480,576)

Who can explain me this in simple terms ?

Thanks.

A TV always leave the edges of the picture outside of the visible area - this is called overscan. To compensate, you can ad some black borders around the image.

OK, But if I watch my video on my computer, these black borders will be visible or the player will remove them automatically ???

Visible. Some few players can zoom.
