Re-Sizing

[Master Yoda]

I was told to add one of these lines to res size the extras on a dvd..

NTSC
for progressive sources
LanczosResize(352,480,8,0,704,480)

if your source is interlaced then
SeparateFields()LanczosResize(352,240,8,0,704,240).Weave()


for PAL progressive
LanczosResize(352,576,0,0,720,576)

interlaced
SeparateFields()LanczosResize(352,288,0,0,720,288).Weave()

if you want to convert lower field first to top field first then
DoubleWeave().SelectOdd().SeparateFields()
LanczosResize(352,288,0,0,720,288).Weave()

But i read somewhere else that you can use ..

BicubicResize(352,480,0,0.50)

So what should i use, dont wanna be using anything to advanced....

BicubicResize(352,480,0,0.50)
Is for NTSC, so you don't need that. Is your pal-dvd interlaced or progressive?

[Master Yoda]

Well most pal stuff is progressive.But i would like to know how to do it for both pal progressive and interlaced.
I would also like to know how to resize ntsc matirial as i have a couple of R1 titles.

Resizing of interlaced is discutable. Simple methode with separate field... will loose and distorse details in some cases.
Better is to make Smoothdeinterlace with double framerate as output. Then resize and restore interlaced frames if want interlaced output.
Of course it's much slower. And still not perfect.

Of course that before starting all this you must determine is NTSC just Telecined FILM or real interlaced video. In case of FILM inverse telecine (or Force Film in DVD2AVI) must be performed before resize.

[Master Yoda]

All this just to resize... i thought it would be just a simple bicubicresize like i used when i done my pal svcds.

I rather not deinterlace, just leave it as it is.Plus most pal stuff is progressive.

[ppera2]

Interlace causes many complications. Therefore people which makes video spots and adverts often shot progressive videos with FILM cameras or special video cameras.
