DVCII and pal to ntsc from vhs with avisynth

[Kilyan]

Hi!

I have to author an ntsc dvd from ntsc dvds and a vhs tape. My vhs player is pal , no way to get ntsc signal from it. The cover of the tape doesn't mention if it is pal or ntsc. I can capture only in pal format from the player with my Dazzle Video Creator II.
The problem is that the dvd I am authoring must be in ntsc.
The following stat is from bitrateviewer from the cap:

Num. of picture read: 226
Stream type: MPEG-2 MP@ML CBR
Resolution: 720*576
Aspect ratio: 4:3 Generic
Framerate: 25.00
Nom. bitrate: 9000000 Bit/Sec
VBV buffer size: 137
Constrained param. flag: No
Chroma format: 4:2:0
DCT precision: 8
Pic. structure: Frame
Field topfirst: Yes
DCT type: Field
Quantscale: Nonlinear
Scan type: ZigZag
Frame type: Interlaced
Scene change detection: FOUND
Variable GOP pattern: NOT FOUND
Notes:

So I have to convert to ntsc. I noticed that for slow motion parts I have no problem using the following script:

-------
LoadPlugin("C:\Program Files\AviSynth2\plugins\MPEG2DEC.dll")
mpeg2source("H:\l_VHS_PAL\1.d2v")
BicubicResize(720,430,0,0.6,24,48,672,480)
AddBorders(0,17,0,33)
AssumeFPS(23.976)
ResampleAudio(44100)
---------

But when I look at the fast clips I captured, I see the interlace (in virtualdub for example). The problem is that, if I use this script for these clips I get a very thick sort of interlace in NTSC.
I think experts here know what I'm explaining.

The interlace in Pal is not a problem because you cannot see it on the tv, but the ntsc version for the fast clips is a crap. So if you have a script that works for the tv it's fine.

So If you have a script for that please help!!!!

(I've been thinking and trying things out for 3 days, very very bored...)

Well... I am no expert, but amateur I shall say.... but I think what you can do (as I am most of my time doing conversions from PAL to NTSC and NTSC DVDs) is convert the video from PAL to NTSC with this app: MainConcept MPEG Encoder, it is exceedingly fast and good; after doing that, use GOOD OLD SLOW TmpegEnc to Deinterlace, nothining else but deinterlace, go to Load and Load DVD (NTSC) and click on setting then open the Advanced tab and check Deinterlace and double click it; check the preview in that moment to see which deinterlace method is best for your movie: there are like 4 with various variants: Even Field, Odd Field, Double, Even-Odd Field.

Since you are just deinterlacing it will be fast, but not too much as Mainconcept's

Also please note that while using TMPEGEnc, if you are doing a deinterlacing from VHS, you would also like to Clean it up using Noise Reduction: also check it and double click it and play around with the settings until you get good results NOTE: I don't know what Still Picture Range or Time Axis are for, however, playing around I noticed that when you put Range all the way up, it will look like a Van Gogh picture

just remember to stick to one fps set (wether 29.97 or 23.9)

I would rather use 29, and the audio that comes with the VHS I also transform it with MainConcept at the same time the video is, so there is no off-sync... you can also see no difference between the PAL and the NTSC version whatsoever (yes I have a trained ear and a trained eye, as far as I can tell)

I'll try out your way!

Thanks
