Jagged Edges

[Rod]

I am using HC14 beta to encode a PAL interlaced -> NTSC DVD conversion. The edges of moving objects are jagged. How do I correct this?

The AVS script I used was:

LoadPlugin("C:\PROGRA~1\DVD2SVCD\AVISYN~1.5PL\Mpeg2dec\dgdecode.DLL")
LoadPlugin("C:\PROGRA~1\DVD2SVCD\AVISYN~1.5PL\INVERS~1\decomb.dll")
MPEG2Source("I:\PAL\PAL.D2V")
Telecide(order=1)
LanczosResize(720,480)
ConvertToYV12()

I used Pulldown after to convert to 29.97.
The file was encoded at 4400 at best quality.

I am experimenting with Tdeint instead of Telecide but I would like some advice on what parameters to use or better a sample script.

You have to know for sure whether your PAL video is really interlaced or just field shifted in order to decide between field matching (Telecide) or deinterlacing (TDeint, KernelDeint, FieldDeinterlace, TomsMoComp, etc.). If it is really interlaced, you don't want Telecide, you want a deinterlacer.

And, of course, pulldown will make it combed again (some of the frames), intentionally! If you don't understand why, you need to learn some fundamentals.

Inspect the video for combing before applying pulldown.

I ran VirtualDub without any filters and the motion although jerky, showed no lines through the frames. The motion in the frames would continuously step forward.
I tried both Tdeint and Telecide both of which appeared to make a smooth M2V 25 fps file but when I ran Pulldown, there was significant combing. See picture
This is a German DVD.
Any suggestions?

As I said, pulldown intentionally produces interlaced frames; that's how it works. But it is not a problem because the DVD will be played on an interlaced device, i.e., an NTSC television. Millions of commercial DVDs work just like that.

Here is the field pattern before pulldown:

A B C D
A B C D

and here it is after pulldown:

A A B C D
A B C C D

As you can see, two of the frames are now interlaced.
