Pal DV 4:3 convert to 16:9 using tmpgenc plus

[SerbianBoss]

I read in dvdlab pro manual how to change from 4:3 picture to 16:9.

Here is how to set the encoding in TMPGenc Plus software encoder:

Start with an NTSC DVD template which creates 720x480 MPEG-2 video. On the Video setting screen, select Aspect ratio 16:9 Display. This will set the flag to be 16:9 so that the DVD player knows that it has to stretch the image. In the Advanced tab in settings, set the Video arrange method to Full Screen (no matter what it will stretch the image to full screen) and then in the filters below select Clip frame. Double-click on it and in the Clip frame tab set Top 60 and Bottom 60. The "Size after clipping" value should now should read 720x360 pixels

Because i am in Europe(PAL) does i need to clip frame to 72 top and 72 bottom instead 60?

And second question how to do the same proces in CCE.

thanks

Hi-

Because i am in Europe(PAL) does i need to clip frame to 72 top and 72 bottom instead 60?

Yes.

And second question how to do the same proces in CCE.

I thought you were handy with AviSynth:

Crop(0,72,0,-72)
Lanczos4Resize(720,576)

And encode in CCE for 16:9.

DV, you say? Interlaced? So, maybe:

LeakKernelBob(Order=1)#if TFF
Crop(0,72,0,-72)
Lanczos4Resize(720,576)
SeparateFields()
SelectEvery(4,0,3)#if TFF
Weave()
ConvertToYUY2(Interlaced=True)

thanks for answer.

With these

Crop(0,72,0,-72)
Lanczos4Resize(720,576)

video is little jerky.

But with second script its all ok.I in CCE select 16:9 aspect ratio.Does something more is need in CCE to select?

I am curios, why in second script we doing reinterlance?(because we dont use any noise filter)?

[manono]

Yes, when encoding interlaced in CCE, you select Alternate Scanning (not Zigzag) and uncheck the Progressive Frame box. If you're in a PAL area, you don't have to worry about GOP lengths.

Why reinterlace? Because the source is interlaced. Before reinterlacing, the framerate is 50fps progressive.

[SerbianBoss]

Yes it would be 50fps if i just doing deinterlance.

But if i
Crop(0,72,0,-72)
Lanczos4Resize(720,576)

source isnt have 50fps right?

[manono]

Yes, that's right, and although I'm no expert on this, never working with DV, and not many interlaced sources at all, you have to be very careful when resizing interlaced sources. There are other ways to handle resizing interlaced sources. I just showed you the one I use. But you know this already, and you also know some of the other ways I think, so I'm not sure why you're asking again. You already know how to filter (denoise) interlaced sources. Resizing is just another kind of filter. By doing this:

Crop(0,72,0,-72)
Lanczos4Resize(720,576)

you destroy the field structure.
